Re: unexpected behavior of FlowPanel's insert method
I realized I didn't need the two elements that came after the content.
So I tried add instead of insert as you suggested, but I still get the same
behavior.

Sure. I used the Showcase sample as a template. They have a tree where
the tree items map to different content widgets.
I've created two Maps: one for history tokens and one for link texts.
Here are the two listeners that use them to figure out what screen to
display:
final HistoryListener historyListener = new HistoryListener() {
public void onHistoryChanged(String historyToken) {
Composite screen = exchangerTokens.get(historyToken);
app.setCurrScreen(screen);
}
};
History.addHistoryListener(historyListener);
app.setListener(new ApplicationListener() {
public void onHyperlinkClicked(Hyperlink link) {
Composite content = exchangerScreenLinks.get(link.getText());
if (content != null !content.equals(app.getCurrScreen())) {
History.newItem(getCurrScreenToken(content));
}
}
});
And here's the setCurrScreen method that calls insert();
public void setCurrScreen(Widget content) {
int currScreenIndex = mainInnerPanel.getWidgetIndex(currScreen);
if (currScreenIndex -1) {
// the screen widget referenced by currScreen was found in
the container
mainInnerPanel.remove(currScreenIndex);
mainInnerPanel.insert(content, currScreenIndex);
}
else {
// the container had not yet been populated
mainInnerPanel.insert(content, 1);
}
currScreen = content;

Hi,
I'm trying to give the impression of navigating through a site by
updating a component contained in a FlowPanel.
Each time I call myPanel.insert(myComponent, index), the contents of
myComponent are repeated. I have some screenshots from running the
debugger in Eclipse if anyone thinks they can help.
In this case, myComponent wraps another FlowPanel. After inserting
into myPanel, the id of myComponent, the FlowPanel it wraps, and the
WidgetCollection inside the FlowPanel are the same. But the id of the
Widget array inside the WidgetCollection changes, and now contains the
duplicated contents.
I don't understand how the object being passed to insert() could be
modified like this.
Thanks
Giles

My application needs to inject some javascript code at runtime (the
code is provided at runtime and can not be inserted in the html page
or loaded using a 'dynamic' script file). The only way I found to do
that is to create an HTML widget. The results are highly dependant on
the browser :
- with Firefox all works pretty well
- with Safari and IE7 it doesn't work at all (javascript code is not
executed). Using Safari development inspector I can see the javascript
code in the DOM, but it's not interpreted by the browser.
So is it really possible to inject javascript using an HTML widget ?
if yes, how ? if no, is there any other way to do it ?
Thanks a lot,

Re: Best image preloading practice?
Thanks for your help. I know this isnt an issue many would come accross, allthough I thought there might be general methods for sensible progressive loading of large content. I should have been a bit more specific with the way the app works, however, as it really does completely rule-out using image bundles for these images. This app is effectively like a game-engine, taking script-files, html and images from directorys on the sever. I'm not constructing the game myself, but rather the method used to create it. The upside of this is its very reusable, the downside is that all images have to be changable on the fly by other people in the team with no-codeing knowledge. Cutting and pasteing images together and clipping them on the client isnt really workable for this. Heck, I really dont have much to do with the game story/puzzle side.I dont speak dutch! :P I guess in some case you could almost picture the game as a gallery application, with the images in a sequence and the goal is for the user to look/comment at one picture while the others are loading. Its not quite the case that the game is so dividable into levels. While it does have chapters which require specific images, theres other images that load at different times, and to some extent the game can be non-liner. Its perfectly possible to make a traditional text-adventure game in this engine, for instance. I have created, however, a master list of images and the most likely order they are needed in. I would have thought the best approach might be to download the images as required for each level as the player advances through the game, and I would think displaying a Loading area... type message after they have completed a level is a traditional approach for games, especially giving them something to read whilst they are waiting. hmz.. Whats wrong with just loading it in the background as they are playing? By the time they done the first few puzzles, really thats enough time for the whole game to have downloaded. Surely todays machines are easily powerfull enough to handel downloading in the background while other stuff is going on? My goal is really to have waiting down to nearly zero, aside from a few seconds at the start. Is it a ram issue? A cpu one? I think in total we are only talking about 20MB of images here, 30MB at most. I'm thinking there should be a way to load continiously in the background, but not to burden the browser with too many call's at once. Cheers, Darkflame On Feb 4, 7:51 pm, gregor greg.power...@googlemail.com wrote: I'm not sure this a best practice issue as such - I think you may have more of an edge case here. I've tried your game (although I can't understand what to do after first screen), but what happens is that the browser is slogging away downloading data (presumably your images) which gives gutter messages and hour glasses etc. This is very distracting, but if you had to wait for the whole lot to download before the game started you'd probably get bored and go somewhere else. I would have thought the best approach might be to download the images as required for each level as the player advances through the game, and I would think displaying a Loading area... type message after they have completed a level is a traditional approach for games, especially giving them something to read whilst they are waiting. This approach is not so well served by GWT because AFAIK you can only have one ImageBundle per module and in any case it is downloaded on initial page load. You may find this thread interesting: http://groups.google.com/group/Google-Web-Toolkit/browse_thread/threa... In it Bruce Johnson comments: 4) History is the answer to apps that are too big. If you combine the points from #2 and #3 above, hopefully it makes sense that whenever you fear your app is becoming too big for a single page, all you need to do is split it into multiple pages such that each page has a unique module with a unique entry point. History smooths all the page junction points, and the compiler is smart enough to eliminate code you don't use from each page's entry point(s). Which would appear to answer the one ImageBundle per module issue and provide convenient inter-level load points. However I would also read what Reinier has to say about it as he also knows what he's talking about. It would certainly complicate your program. Failing that, you could consider handling image strips yourself. You assemble a single composite image manually of all images required for a single level in some convenient extraction grid. Then you use an Image object for this composite image, but before you give it the URL, you attach a LoadListener to it - this is so can tell when its finished loading in your code and control the loading message and the UI during level load procedure and kick off extracting the individual image parts etc. It's a bit tricky to extract bits of one image to create

Call event after an other
Hi! If I have following problem: I enter some text in a textbox. Now I click on a button to save data to a database. With leaving the edit ists onChange- event is called, but the onClick- event of the button is called too at same the time. Saving is faster than onChange. I tried to handle the onClick after other events have done their work by using a DeferedCommand. But is doesn't work. Saving is allways faster than the onChange. Is there a way to control the handling-order of events? Thank you! -Danny --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Script error in IE 7 in web mode
I have a GWT application that runs OK in hosted mode. When I compile it, it gives a script error on Internet Explorer 7. The compile version runs correctly in Firfox, Chrome and Safari. I've turned on script debugging in IE7 and it gives me the following message (translated from Dutch) -- Line : 2 Character : 23530 Error : Exception activated but not handled Code: 0 - Can anyone point me to some documentation how I can further investigate what's wrong. The application is quite big, so it's not so easy to isolate the piece of code where it goes wrong.

Re: Best image preloading practice?
I'm not sure I can be of much more help on this myself, since I have never written anything like this, and I have not come across any specific posts about it I can recall - maybe some members have, so you can hope A few ideas/comments in-line: On Feb 5, 11:42 am, darkflame darkfl...@gmail.com wrote: Thanks for your help. I know this isnt an issue many would come accross, allthough I thought there might be general methods for sensible progressive loading of large content. This question does come up quite a lot and has been answered including in the link I gave you (where it comes from the horses mouth). The fundamental issue is that the GWT compiler performs serious optimization at compile time to reduce javascript file size. To do that it produces a single js file at compile time and does not support the idea of loading the application in chunks unless you do the multiple module with separate entry point thing. You can read the thread and others for technical details. I should have been a bit more specific with the way the app works, however, as it really does completely rule-out using image bundles for these images. This app is effectively like a game-engine, taking script-files, html and images from directorys on the sever. I'm not constructing the game myself, but rather the method used to create it. The upside of this is its very reusable, the downside is that all images have to be changable on the fly by other people in the team with no-codeing knowledge. Cutting and pasteing images together and clipping them on the client isnt really workable for this. Heck, I really dont have much to do with the game story/puzzle side.I dont speak dutch! :P I guess in some case you could almost picture the game as a gallery application, with the images in a sequence and the goal is for the user to look/comment at one picture while the others are loading. Its not quite the case that the game is so dividable into levels. While it does have chapters which require specific images, theres other images that load at different times, and to some extent the game can be non-liner. Its perfectly possible to make a traditional text-adventure game in this engine, for instance. I have created, however, a master list of images and the most likely order they are needed in. Another classic approach is the maze design (I think this is how trad text adventures where generally done). You have rooms with doors (or walls) connecting to other rooms. You have the maze defined in a data structure on the server, and when player gets to a room (i.e. a location), you download each of the rooms they can move to next which are specified as properties of the doors. Each room has its associated script file and images etc. I think this is fairly common and you will probably find ready made code examples around the web. The Gang of Four use it as example in introduction to creational patterns chapter in the famous book. The big issue is how many separate images are required for each location. If its basically only one, its easy. You fetch the location scripts and data for each adjoining room over GWT RPC (very quick) which includes image ID's. Then you fetch the room image for the room they go to (again very quick if images are 100-200Kb etc). If several images, you have a multiple HTTP call problem which you really want to avoid. That's the idea behind the composite image strip. Much faster. It's what good image galleries do with thumbs for example. I would have thought the best approach might be to download the images as required for each level as the player advances through the game, and I would think displaying a Loading area... type message after they have completed a level is a traditional approach for games, especially giving them something to read whilst they are waiting. hmz.. Whats wrong with just loading it in the background as they are playing? By the time they done the first few puzzles, really thats enough time for the whole game to have downloaded. Surely todays machines are easily powerfull enough to handel downloading in the background while other stuff is going on? My goal is really to have waiting down to nearly zero, aside from a few seconds at the start. As I mentioned having the browser download the images via simple URL to image location is distracting for the player as the browser reports progress all the time. If you use your own file download servlet called repeatedly you avoid that problem, it does happen invisibly in background. Use standard HttpServlet and feed its URL + image ID param into Image object constructors. Lots of examples for this in group and around net. Is it a ram issue? A cpu one? I think in total we are only talking about 20MB of images here, 30MB at most. You are thinking of loading 20MB of images into the DHTML DOM of you application. The DOM is maintained by the browser, and it is not designed to deal with 20MB documents (big e.g.
Re: Get remaining height of a panel or window
It sounds as though you are calling getOffsetHeight before the display has been fully rendered. A solution is to put your sizing algorithms inside a DeferredCommand. That way panel A should have been rendered already, and now it will have its height property set.

Re: View remaining content of a full ocuupied window after resizing
Hi Aragorn, Enabling scrolling in Window class should give you main window scroll bars. Resizing the browser window can be difficult to get right, it depends on your application. If all your widgets are sized relatively in percentage terms then sometimes it works out OK automatically. If not you can attach a WindowResizeListener to your EntryPoint class and kick off resizing algorithms from the onWIndowResize(..) method. regards gregor On Feb 5, 1:09 pm, aragorn sagar5...@gmail.com wrote: I have created a webpage which fits itself to the size of the browser window at start.

Hi. I have a problem forgwt-fabridge. I think it may be a critical
issue forgwt-fabridge.
If a swf widget is added into a panel, and then add the panel into a
container. And then remove the panel from the container, and then add
the panel back into the container. Then the Null pointer error will
occur at onInitialization()caused by the swf widget. I did a test using
the FABridgeDemo. In the FABridgeDemo, I added a button for removing the
swf widget.
When start the program, first click the Add new SWF, and everything is
ok. Then click the Remove SWF, then the swf is removed. Then click the
Add new SWF again, then an error will happen.
I have tried many ways, the only way to make it work is to create the
swf widge again and using a different name if the widget has been
removed. For example:
java.util.Date date = new java.util.Date();
swfWidget = new
SWFABridgeWidget(app.swf,400,400,example+date.getTime());
But it is not good at all. And the behavior is not the same as other
regular gwt widgets. For other widgets, after they are put in a panel.
Then you can add/drop this panel into/from a container many times
without re-create the inside widgets.
I am really frustrated about this problem. Based on user's selection we
will add different panels into a container for display. It is really
painful if we have to create the swf widgets again if the panel has been
dropped from the container once.
I don't know whether the following code in
pl.rmalinowski.gwt2swf.client.ui.SWFWidge causes problem or not.
protected void onUnload() {
// GWT.log(onUnload, null);
getElement().removeChild(DOM.getFirstChild(getElement()));
isSWFInjected = false;
super.onUnload();
}
The statement: getElement().removeChild(DOM.getFirstChild(getElement()))
removes the child from the widget. Thus after a swfwidget is removed
from a panel, and then add the swf back, no child there.
Following is the code in com.google.gwt.user.client.ui.ComplexPanel
@Override
public boolean remove(Widget w) {
// Validate.
if (w.getParent() != this) {
return false;
}
// Orphan.
orphan(w);
// Physical detach.
Element elem = w.getElement();
DOM.removeChild(DOM.getParent(elem), elem);
// Logical detach.
getChildren().remove(w);
return true;
}
It sounds to me that the different between two programs is that in
ComplexPanel, it removes the widget's element only, but in SWFWidge, it
removes the child of the widget's element.
Thank you very much!

Re: ScrollPanel maxWidth or maxHeight?
Hi Alex, I think you have to explicitly specify the height of a ScollPanel in pixels to get the scroll bars to kick in, and that will set the height of the panel from the word go. If what you mean is that you want a panel to start at a minimum size, then grow as things are added to it, but then to stop growing and go into scroll mode at a certain point, I do not think that is realistically possible since there is no event you can listen for that would tell you when the panel had grown to a given height. You can listen for the browser window changing, but not for an individual panel. I suppose one approach might be to set up a timer to check the current height at intervals and take appropriate action when it hit the limit, but this sounds very inefficient. regards gregor On Feb 5, 9:29 am, alex.d alex.dukhov...@googlemail.com wrote: Hi folks, I'm trying to impelement a scrollpanel that becomes bigger (height) to the certain size (maxHeight) when populating it with data.

the panels as above. Any ideas or suggestions for a work around?

How GWT/Ajax Image viewer/editor
Can someone guide me as to how one would go about to build a very very simple multi-page image (TIFF) viewer/editor using GWT. The interface would be similar to Adobe Reader with page thumbnails on the left and the actual page image on the right. Additionally, the actions allowed on this multi-page TIFF image would be rotate, delete one or more of the embedded pages. What I have so far is that I think: 1) The GWT DockPanel can be used to display the Actions Menu bar on the top (NORTH), thumbnails Vertical panel on the left (WEST) and ScrollPanel with Image in the center (CENTER) 2) The rotation of images can be done using GWT-RPC and Java Advanced Imaging (JAI) API on the server side.

Re: IE 7.0 Issue with ScrollPanel
Hi All,
I finally found a solution to this and it appears to work everywhere. The
problem was definitely assocated with the ScrollPanel. Instead of directly
add the scroll panel to my dock panel, I made a composite widget that
contained a tree on a scroll panel on a vertical panel. I call initWidget
only on the vertical panel. When I do the resizing, I adjust the size of
the scroll panel. This works on all my target browsers.
Thanks,

Hi All,
I have a small application that works great in FireFox and Safari but every

error. The following is JavaScript code contains the error:

var shortcutHeight;

this$static.scrollPanel.element.style['height'] = shortcutHeight + 'px';

It fails when shortcutHeight is set. I can associate this with the
following lines of GWT java code:
public void onWindowResized(int width, int height) {
int shortcutHeight = height - scrollPanel.getAbsoluteTop() - 8;
if (shortcutHeight 1) {
shortcutHeight = 1;
}
scrollPanel.setHeight(shortcutHeight + px);
objectDetail.adjustSize(width, height);
}
The line
int shortcutHeight = height - scrollPanel.getAbsoluteTop() - 8;
appears to be the problem. The variable scrollPanel is of type
ScrollPanel. It contains a Tree. If I remove the scroll panel and just
display and resize the tree it works but I now longer have scrolling and the
tree falls off the screen. I read somewhere that you should be careful when
you attempt to resize widgets and that sometimes it works and other times it
does not depending on how the widget is rendered. Is this the source of the
problem?
My real goal is to layout an application like the a mail application (from
the GWT Tutorial) with the left hand side containing a scrolling tree
control. To support this I create a ScrollPanel and add my tree. I then
set the height when the window is resized. This creates the desired effect
on all platforms except IE. Any suggestions on how I can support this?
Thanks,

Re: Script error in IE 7 in web mode
Hi Danny, I had a similar problem when I was parsing an XML document. In my case, I was a little careless about trapping errors and casting classes. As it turned out Safari and Firefox ignored the errors while IE generated an error. I was able to identify the offending lines of code and rewrote them and made sure that I caught all the errors.

Calling Embedded Object's Methods from GWT
Hello,
I'm working on a system which Integrates an embedded object in a GWT
application.
Part of the HTML page I have the following content:
object style=position: absolute; left: 296px; top: 140px
width=400 height=300 classid=clsid:02BF25D5-8C17-4B23-BC80-
D3488ABDDC6B codebase=http://www.apple.com/qtactivex/qtplugin.cab;
id=qtmovie_object style=behavior:url
(#qt_event_source);
param name=src value=http://www.ics.uci.edu/~ronen/rak_demo/
Welcome.mov
param name=autoplay value=false
param name=postdomevents value=true
/object
Then from GWT I call the different methods of this object for example:
public static native int getSmilDuration() /*-{
var obj = $doc.getElementById('qtmovie_object');
if (obj!=null)
return parseInt(obj.GetDuration()/obj.GetTimeScale());
else
return 1; // added to avoid cases where null is access or
division by zero.
}-*/;
This works well in IE. However, it will not work on Firefox or
Safari.
I get the following error on Firefox (there is another native function
which calls obj.Stop():
Error: edu_uci_ics_client_StreamViewer_SMILStop___obj_0.Stop is not a
function
Source File:
http://128.195.185.30:/edu.uci.ics.StreamViewer/537510C75B4C3BD5CE0E2BC9A9E96FA9.cache.html

And some cryptic error on Safari:
undefined
http://128.195.185.30:/edu.uci.ics.StreamViewer/2647FE5FEBC5958D96D8CF4F49CF5E2D.cache.html

Any ideas???

Re: getting members of the outer class
I try to suggest you something, but I hope not to give a trivial
suggestion to you...
Are you sure that you call MediaStation.getXMLContent() after the
callback returns? For what I can read in your code, you send the
callback in the try / catch block, then the next statement that is
executed is return MediaStation.result. So you may not have finished
the callback execution at that point. Anyway this is a way of using a
getter function in conjunction with a request that I have never seen before.

If the data insertion call is happening from some UI action then in the onSuccess of insertion call you can tell the tree to update itself.

Hi,
I'm trying to give the impression of navigating through a site by
updating a component contained in a FlowPanel.
Each time I call myPanel.insert(myComponent, index), the contents of
myComponent are repeated. I have some screenshots from running the
debugger in Eclipse if anyone thinks they can help.
In this case, myComponent wraps another FlowPanel. After inserting
into myPanel, the id of myComponent, the FlowPanel it wraps, and the
WidgetCollection inside the FlowPanel are the same. But the id of
the
Widget array inside the WidgetCollection changes, and now contains
the
duplicated contents.
I don't understand how the object being passed to insert() could be
modified like this.
Thanks

Re: ScrollPanel maxWidth or maxHeight?
Oh, in your use case, Alex, you do have an event - adding an item to the panel. Just check the height after new item added and set the height of the ScrollPanel in pixels if max value reached I would think answers. I have looked in vain for a general method to get ScrollPanels to resize and generally behave by themselves. I think the reason is that individual divs/table cells etc do not generate events when their size changes. ScrollPanel is basically a div with an overflow setting. I have supposed this is because there can be hundreds if not thousands of boxes on a page, so if they all emitted an event every time they changed their width/heights the browser's event queue would be brought to its knees.

Re: getting members of the outer class
I'll try, hoping to be helpful! A lot of code decision depends on
exactly what you want to do with this code. I do some assumption now:
1- you need to load at some kind of startup your variable 'result '
2- you need to read the content of the 'result' variable later in the code.
I would do something as follows for what concerns MediaStation class:
public class MediaStation{
private static String result = nothing;
public static String getXMLContent(String path){
return MediaStation.result;
}
public static void loadResultVariable() {
RequestBuilder requestBuilder = new
RequestBuilder(RequestBuilder.GET, path);
try {
requestBuilder.sendRequest(null, new RequestCallback() {
public void onError(Request request, Throwable
exception) {
MediaStation.requestFailed(exception);
}
public void onResponseReceived(Request request,
Response response) {
MediaStation.result = response.getText();
}
});
} catch (RequestException ex) {
MediaStation.requestFailed(ex);
}
}
}
(I have not tried to compile this code, please consider there may be errors)
Then from outside this class I would call loadResultVariable() at the
beginning, that is when your code is initializing. Then you can use
easily getXMLContent, but after having ensured that the server request
has already finished.
Note that there are many other issues that can arise due to callbacks,
issues that can be addressed in many ways, but I suppose you can get a
lot of info about them.

how to access objects from another frame?
His, Read some posts in the group and still wondering if implementing such a scenario would be possible with GWT: A web page is served which contains two frames - one for presenting the stuff and the other one to constantly make requests to the server (a timer) and maintain latest of data (lots of objects, so only the new data is added / removed and not everything at once). Is there a way for one frame to get a reference to the other where the current data resides? The obvious benefit would be that when user clicks a link and goes to a different page the data is still in the other frame and there is no need to load everything over again. Has someone maybe already done that or experienced a similar challenge? That's my view on the problem. But maybe there can be another way to retain pieces of working logic and current data without frames when a user jumps to physically distinct html page.

Re: Hosted Mode not refreshing
I figured this out and I'm sad to say it was user error *sigh*.

Re: getting members of the outer class
like you already said, it is indeed a problem that the callback
request isn't finished in the time the value is returned. i'll figure
this out now.
thanks for your patience!

I'll try, hoping to be helpful! A lot of code decision depends on
exactly what you want to do with this code. I do some assumption now:
1- you need to load at some kind of startup your variable 'result '
2- you need to read the content of the 'result' variable later in the code.
I would do something as follows for what concerns MediaStation class:
public class MediaStation{
private static String result = nothing;
public static String getXMLContent(String path){
return MediaStation.result;
}
public static void loadResultVariable() {
RequestBuilder requestBuilder = new
RequestBuilder(RequestBuilder.GET, path);
try {
requestBuilder.sendRequest(null, new RequestCallback() {
public void onError(Request request, Throwable
exception) {
MediaStation.requestFailed(exception);
}
public void onResponseReceived(Request request,
Response response) {
MediaStation.result = response.getText();
}
});
} catch (RequestException ex) {
MediaStation.requestFailed(ex);
}
}}
(I have not tried to compile this code, please consider there may be errors)
Then from outside this class I would call loadResultVariable() at the
beginning, that is when your code is initializing. Then you can use
easily getXMLContent, but after having ensured that the server request
has already finished.
Note that there are many other issues that can arise due to callbacks,
issues that can be addressed in many ways, but I suppose you can get a
lot of info about them.

Are you sure that you call MediaStation.getXMLContent() after the
callback returns? For what I can read in your code, you send the
callback in the try / catch block, then the next statement that is
executed is return MediaStation.result. So you may not have finished
the callback execution at that point. Anyway this is a way of using a
getter function in conjunction with a request that I have never seen
before.

Re: how to access objects from another frame?
If you can accept browser's plugins in your project, take a look at Google Gears. With this, you can take a better control of locally stored data and much more ... http://gears.google.com/ 2009/2/5 asdf_asdf denis.ergashb...@gmail.com His, Read some posts in the group and still wondering if implementing such a scenario would be possible with GWT: A web page is served which contains two frames - one for presenting the stuff and the other one to constantly make requests to the server (a timer) and maintain latest of data (lots of objects, so only the new data is added / removed and not everything at once). Is there a way for one frame to get a reference to the other where the current data resides? The obvious benefit would be that when user clicks a link and goes to a different page the data is still in the other frame and there is no need to load everything over again. Has someone maybe already done that or experienced a similar challenge? That's my view on the problem. But maybe there can be another way to retain pieces of working logic and current data without frames when a user jumps to physically distinct html page.

Re: Best image preloading practice?
I'm not sure I can be of much more help on this myself, since I have never written anything like this, and I have not come across any specific posts about it I can recall - maybe some members have, so you can hope... Thats ok, anythings welcome :) The fundamental issue is that the GWT compiler performs serious optimization at compile time to reduce javascript file size. To do that it produces a single js file at compile time and does not support the idea of loading the application in chunks unless you do the multiple module with separate entry point thing. You can read the thread and others for technical details. No,no thats ok, I'm not interested in loading the app in chunks, just the images. Everything else can stay. Another classic approach is the maze ... The big issue is how many separate images are required for each location. The maze design is good, and I could certainly extract the possible- routes from my script controll. Allthough its impossible to say how many images there could be really. If there was 3 or 4 possible routes from a point, each leading to a location (which might have a picture or might not), and a few items in each location (each item might have a picture, or even a few), it quickly adds up. The maze seems to be a good optimisation, nethertheless, but there would still need to be a loading-system within it. . If you use your own file download servlet called repeatedly you avoid that problem, it does happen invisibly in background. Use standard HttpServlet and feed its URL + image ID param into Image object constructors. Lots of examples for this in group and around net. Ah, this sounds quite usefull to hide the loading, allthough I'll have to read up. I assume this is how, say, GoogleMaps does it? You are thinking of loading 20MB of images into the DHTML DOM of you application Am I? Does the DOM keep them there even when not displayed? These images certainly wouldnt be displayed all at once. 1 or 2 at a time at most. I figured I was just giving them a chance to be put in the browsers cache :-/ Sure, some users might have a heavily restricted cache, or even off, but I think they are in the gross minority. (and if they have no image cache, then they probably are used to waiting for images loading anyway). But the vaste majority of players should happily be able to load 20-30MB onto their hard disk for the course of the game. They are deliberately designed to make downloading huge chunks of binary data difficult, especially transparently, and they are not expecting to have to display 20MB worth of images at once. Again, not at once. Surely a staggered download they wouldnt have a problem with? Emulating, say, what it would expect from a user browseing DeviantArt? If you leave it to the browser, it makes one Http call per image and you cannot guarantee the order they will be fetched. I Yes, I noticed this already. Its interesting, as I expected it to be in a first-come-first-served base's, but I guess theres some optimisation within a timeframe. I do wonder though what the limit of this is and if its the same per browser. (I mean, if I loaded no more then 1 image every 10 seconds, it would probably do it in the order I asked, but not if I asked for one to be prefetched every 10ms) This is more a curiousity though. . The point of the composite image strip is to fetch several images in one request since they come in a single binary file. Yes, I understand the point of them, and I think image bundles are a great idea. (In fact, online in general, theres probably a lot of wasted bandwidth used on little UI elements on webpages..like 5kb gifs etc) In this specific case though they arnt approperate.

Help with GWT
I am working in a port of a very large Java application to PHP. The required path was to modify the Java2Javascript compiler to produce PHP code instead of JavaScript. Right now I have found: JavaToJavaScriptCompiler: I understand that this is the main class. JavaToJavaScriptMap.java: My hope was to see the actual map of java keywords etc to the javascript equivalents. In other words I am confused. If you could help me to: 1. Find the relevant classes for building and stand alone java to javascript translator. 2. Is there a stand alone version that only takes a java project (or file) and just output the JavaScript file? 3. Can the GWT save the java AST to a file? Note: I understand this is not a PHP forum, so the PHP problem is mine. The questions refers to stage one: understanding and compiling a clean Java to Javascript translators.

Re: Script running slow error in IE
Make use of DeferredCommand when performing intense UI updates. The drop downs could be lazy loaded as when the user clicks on them the content gets loaded from the server. I hope that leads you into the right direction to fix your problem. I believe there is an incremental DeferredCommand which you could try when adding items to a drop down box. If the error occurs when you remove the form then you could try setting the visibility to hidden and try to use the deferred command to itterate through it to remove the widgets from memory afterwards.

Re: Can we load an html file and add it as a Widget?
Just use the RequestBuilder class and do a get request for your html file. Create the html panel and use DOM to set the inner html (DOM.setInnerHTML()) with the String returned from the request builder callback. You can then do myPanel.addAndReplaceElement(widget,id); I am doing this now in my current project. Make sure to check the response code is = 200 so you can handle any errors. You would want to check this in the onSuccess for the RequestBuilder because it treats 403 errors ,if i am not mistaken, as being successful. Hope that helps.

Re: Deploying a GWT application
O.K. the compiler spits out pretty much everything that was in a public path, so expect to see those in the output (www) directory. in addition you'll likely see some of the following: [module_name].nocache.js - this is the bootstrap file that loads the actual GWT module. [hash].cache.html - These are the actual javascript payload files tailored for each individual browser/i18n combination. [hash].cache.png - These are generated imagebundle files [hash].gwt.rpc - these are rpc serialization policy files clear.cache.gif - blank gif used by GWT for some tasks history.html - used for history support hosted.html - used for hosted mode support (debugging against a live server) You'll want to deploy all of these. The hosted.html could be omitted, however that would prevent you from stepping through the code running on your live site, so just leave it. -jason On Feb 5, 2009, at 12:14 PM, RussAbbott wrote: When I compile my GWT application I get 13 files, including the .html and .nocache.js files.

Re: Best image preloading practice?
Ah, this sounds quite usefull to hide the loading, allthough I'll have to read up. I assume this is how, say, GoogleMaps does it?

These images certainly wouldnt be displayed all at once. 1 or 2 at a time at most. I'm not absolutely sure, but I think if you load an image it is basically attached to a document, whether the browser caches it or not, and whether it is currently visible of not. You don't control the browser cache, I mean I don't think you can tell it to conveniently download all your images and store them neatly on disk until you need to display them for example. It's also more than likely each browser does things differently. But the vaste majority of players should happily be able to load 20-30MB onto their hard disk for the course of the game. That's my point: I don't think it works like that, I can see why it would be nice for you if it did. The browser probably does store images locally in some circumstances, but I believe this would be for virtual backing for the document it's loaded/displaying if required for memory management purposes. I.e. you've got a document of 20MB loaded which it must manipulate. I may be wrong, you'd need to investigate to be sure. They are deliberately designed to make downloading huge chunks of binary data difficult, especially transparently, and they are not expecting to have to display 20MB worth of images at once. Again, not at once. Surely a staggered download they wouldnt have a problem with? Emulating, say, what it would expect from a user browseing DeviantArt? yeah, the staggered download is basically the idea of the maze - each time you move to next location you've only got one locations worth of images to fetch. Or if it worked fast enough you could fetch all the required images for the adjoining locations so they would be ready to go instantly. It depends entirely on no of image bytes per location. Point is doing it this way old images are thrown away and can be garbage collected as you go, so you are not accumulating images in memory. It's stable. (assuming I'm right about the how this works of course). If you leave it to the browser, it makes one Http call per image and you cannot guarantee the order they will be fetched.

This is exactly what the GWT ImageBundle does (and what has been best practice in web design for years). Annoyingly for you GWT only does this once per module because Bruce says they can't think of a single use case for needing separate ImageBundles! My bet is that if you just start loading all the images as you are suggesting, you will have to attach them to the DOM somewhere, so ultimately what you will be doing is building the entire game at the same time as the player is trying to play the first locations. So my betting is three to one on a) whilst this build is going on the game play will be badly affected at precisely the time you least want it to, and b) once you've loaded it all it will run like a dog anyway. I may well be wrong, but if I'm not, and you looked at the maze idea as plan B, then using image strips a la ImageBundle will make the game run much faster and smoother, so the effort might well be critical in the end. This is after all the heart of your technical challenge. This has been done so many times I expect you will find some javascript code that cuts them up (or maybe CSS stuff) to crib from somewhere and some server side tools to pack the image strips as well.

Re: Stack overflow at line: 0
If you do some searching on this I think you will find that it is related to javascript code that is making recursive or repeated calls to the same javascript method. I think IE is treating this as some sort of warning/error to guard itself against potential stack overflow problems. I have chased this problem for many hours. Happens frequently in IE 6 but less of an issue in IE7 and probably related to javascript performance. I think I remember this was an issue in google generated RPC code that may have been fixed in GWT 1.5.x. Search on stack overflow in the message group and you should be able to find it.

Now I have another question. In this task, I'm attempting to use GWT to enhance an existing web page. I've done the development by using a mock-up of the page that the server actually generates. That is I took a generated page from my browser, saved it as html, and did my development in terms of that html. In reality I'll need to insert my GWT code into generated html pages as they are generated. I'm sure that the documentation tells me how to do that, but I couldn't find it. I looked at the html generated by the compiler in my development environment hoping to find an onModuleLoad(). But it was the same as the html I started with. I thought I might simply put an onModuleLoad () call in the generated page as a way get the whole thing going on the client side. But apparently that's not the way to do it. Would you let me know the right way. What is it that gets the generated GWT code to start running on the client side?

Re: Best image preloading practice?
Hi darkflame, I think the best way of (pre)loading images depends on the kind of app you have. I visited the url you shared with us and run a Fiddler2http://www.fiddler2.com/session through it to discover that around 100 requests are fired to get icons, textures, buttons, gradient bars, etc which could be loaded all in one request using an ImageBundle and doing that will surely improve the loading time of the app. Then you have like another 100 requests that fetch a combination of thumbnails and bigger images with good quality (ranging from 10kb to 1 meg aprox). For what I saw many of these images are displayed only when the user clicks on the inventory bag (thumbnails) and then when a thumbnail is selected the bigger image is displayed so I think you could also use Image.prefetch to, for example, get all the thumbnails when the initial screen is loadad (so that when a user clicks on the bag they appear quickly) and also prefetch the bigger images when the user clicks on the bag so that when a thumbnail is clicked the big image appears quickly also... or maybe you could just load a big image when it is needed! I think these are the kind of decission you can only make by having the app running and using tools like Fiddler2 or Firebug to see loading times, number of requests, use of browser cache, etc. I hope this helps, Martin On Thu, Feb 5, 2009 at 5:24 PM, gregor greg.power...@googlemail.com wrote: Ah, this sounds quite usefull to hide the loading, allthough I'll have to read up. I assume this is how, say, GoogleMaps does it? I think it's quite common where you want to have control over how images are handled yourself - as I say there are plenty of examples around of how to do the serlvet. You are thinking of loading 20MB of images into the DHTML DOM of you application Am I? Does the DOM keep them there even when not displayed? These images certainly wouldnt be displayed all at once. 1 or 2 at a time at most. I'm not absolutely sure, but I think if you load an image it is basically attached to a document, whether the browser caches it or not, and whether it is currently visible of not. You don't control the browser cache, I mean I don't think you can tell it to conveniently download all your images and store them neatly on disk until you need to display them for example. It's also more than likely each browser does things differently. But the vaste majority of players should happily be able to load 20-30MB onto their hard disk for the course of the game. That's my point: I don't think it works like that, I can see why it would be nice for you if it did. The browser probably does store images locally in some circumstances, but I believe this would be for virtual backing for the document it's loaded/displaying if required for memory management purposes. I.e. you've got a document of 20MB loaded which it must manipulate. I may be wrong, you'd need to investigate to be sure. They are deliberately designed to make downloading huge chunks of binary data difficult, especially transparently, and they are not expecting to have to display 20MB worth of images at once. Again, not at once. Surely a staggered download they wouldnt have a problem with? Emulating, say, what it would expect from a user browseing DeviantArt? yeah, the staggered download is basically the idea of the maze - each time you move to next location you've only got one locations worth of images to fetch. Or if it worked fast enough you could fetch all the required images for the adjoining locations so they would be ready to go instantly. It depends entirely on no of image bytes per location. Point is doing it this way old images are thrown away and can be garbage collected as you go, so you are not accumulating images in memory. It's stable. (assuming I'm right about the how this works of course). If you leave it to the browser, it makes one Http call per image and you cannot guarantee the order they will be fetched. I Yes, I noticed this already. Its interesting, as I expected it to be in a first-come-first-served base's, but I guess theres some optimisation within a timeframe. I do wonder though what the limit of this is and if its the same per browser. (I mean, if I loaded no more then 1 image every 10 seconds, it would probably do it in the order I asked, but not if I asked for one to be prefetched every 10ms) This is more a curiousity though. . The point of the composite image strip is to fetch several images in one request since they come in a single binary file. Yes, I understand the point of them, and I think image bundles are a great idea. (In fact, online in general, theres probably a lot of wasted bandwidth used on little UI elements on webpages..like 5kb gifs etc) In this specific case though they arnt approperate.

Re: getting members of the outer class
You need to rethink your approach a bit more.
Making an asynchronous call inside a synchronous method will not
produce the results you want.
You should make the asynch call, then do whatever you want to do with
the XML result inside the callback. This means that the
onResponseReceived needs to initiate the action that uses the returned
xml.

I would do something as follows for what concerns MediaStation class:
public class MediaStation{

public static void loadResultVariable() {

Then from outside this class I would call loadResultVariable() at the

easily getXMLContent, but after having ensured that the server request
has already finished.
Note that there are many other issues that can arise due to callbacks,
issues that can be addressed in many ways, but I suppose you can get a
lot of info about them.

Are you sure that you call MediaStation.getXMLContent() after the

executed is return MediaStation.result. So you may not have finished
the callback execution at that point. Anyway this is a way of using a

Implementing Throwable getStackTrace()
Hi All, I am interested in implementing Throwable getStackTrace() in the actual browser JavaScript. I realize it works in hosted mode when running in a actual JVM. Is this even possible since the auto generated JavaScript is so different from the Java or was it just not attempted? I do remember seeing the line number of JavaScript errors in IE and Firefox during the years when I used to write JavaScript by hand. Could the GWT compiler simply figure out where the Exception is getting thrown by looking for lines like; new Exception(); And then put the line from the Java source code along with the class into the JavaScript I realize actually going up the stack would be difficult since it would require something like reflection/native jvm calls. But even one StackTraceElement might make GWT much more user friendly.

Re: View remaining content of a full ocuupied window after resizing
Well I have not used WindowResizeListener in my code. Instead I have used CSS wherein i state the min-width and min-height for mu main window and whenever the window is resized beyond this minimum specification, a scrollbar appears. Also some of my widgets have their widths/heights in percentages while some have those in pixels(all using CSS). Thats why it gets difficult for me since i am never sure what i should set in CSS coz again different browsers and OS treat them differently.

Resizing the browser window can be difficult to get right, it depends on your application. If all your widgets are sized relatively in percentage terms then sometimes it works out OK automatically. If not you can attach a WindowResizeListener to your EntryPoint class and kick off resizing algorithms from the onWIndowResize(..) method. regards gregor On Feb 5, 1:09 pm, aragorn sagar5...@gmail.com wrote: I have created a webpage which fits itself to the size of the browser window at start.

Re: Deploying GWT application (WAR)
Well for web application you dont give the user a WAR file, but you deploy the war file on a server machine (where you have an application server like Tomcat installed) and then give the url of the application to the user. User will use his browser to open ur URL. - litty On Fri, Feb 6, 2009 at 4:13 AM, Jonathan jonathan.delf...@gmail.com wrote: Hi to all, I managed to install properly gwt that runs fine under my linux.

Re: Caching question - using GWT to create Google Gadgets
I noticed in the comiled code a lot of calls using: _IG_GetCachedUrl()
that's excellent! and just the way I want it.
However - that does then leave something to be desired when you are
developing and making changes frequently.
In those case it would be nice to have { refreshInterval: 0 } passed
to the function.
Ideally you would be able to set some sort of DEBUG_P = 1 flag in the
file that control this behavior.
Any suggestions?
And if I may be so forward - if there isn't yet a straightforward
solution - maybe this can be a request for future versions of the GWT

I have

which details how you can now use the legacy gadgets API with GWT to
create gadgets.
I also noticed that the way the GWT seems to achieve cross browser
compatibility is to create multiple javascript files and dynamically
include the right ones.
I am worried about the performance hit of hosting uncached files on my
webserver.
My question is this: does the GWT cache requests to these javascript
files?
No, GWT doesn't actually cache them. It routes the request for your
compiled resources through a proxy which is supposed to cache them
(for up to 1 hour, I believe)
Historically my process has been to have the entiregadgetinline as
type html and where necessary only include external resources after
using a call to _IG_GetCachedUrl so that they are proxies by google.
So to clarify, my question is: When GWT spans it's code across
multiple files does it use _IG_GetCachedUrl to cache the request of
external javascript - or if not does it at least do something to
ensure that the javascript will not be requested (from my webserver)
every time a user loads thegadget.
Turn onprettymode when you compile, and then look at the generated
.gadget.xml file (add -stylePRETTYto the command line) and you'll
see that this is exactly the strategy used in the compiledgadget.
just curious because on of the things I love about the wholegadget
space is that it has let me develop interesting projects in a way that
doesn't put much load on my puny server.
There are things you need to watch out for. Make sure you load your
.css files through a script take in your module definition
(.gwt.xml). Also, images could be an issue, but you can translate the
urls to images to go through the proxy with the same _IG_GetCachedUrl
call manually, or you can use the new GadgetImage class (in the next
public update, due out very shortly).

Why can't I use GWT Theme support with a Gadget?
;) In the FAQ it explains how GWT references a CSS file with relative image paths. When the GWT app in question is a gadget it is hosted through a proxy by the gadget container and all the relative image paths break. There are two issues here. 1) It would be nice if there was a way to indicate where the final home of the images would be so that the GWT compiler could build absolute paths 2) It would be even better if the reference to the images were wrapped in calls to _IG_GetCachedUrl() - I'm not sure if this is possible with an external CSS file, but I know it can be done when the CSS is inline. Any info on if these issues are being addressed? Any thoughts on solutions/hacks in the meantime? I guess worst case I can just inline the CSS manually - but hey, I'm lazy :) thanks for the help/info! --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Best image preloading practice?
You are thinking of loading 20MB of images into the DHTML DOM of you application Am I? Does the DOM keep them there even when not displayed? These images certainly wouldnt be displayed all at once. 1 or 2 at a time at most. I'm not absolutely sure, but I think if you load an image it is basically attached to a document, whether the browser caches it or not, and whether it is currently visible of not. You don't control the browser cache, I mean I don't think you can tell it to conveniently download all your images and store them neatly on disk until you need to display them for example. ah, pig. I thought that was exactly that prefetch was doing -sigh- I thought it loaded it to ram first, then the browser keeps a copy in its cache for reloading if needed. -sigh- That does change things indeed then. Again, not at once. Surely a staggered download they wouldnt have a problem with? Emulating, say, what it would expect from a user browseing DeviantArt? yeah, the staggered download is basically the idea of the maze - each time you move to next location you've only got one locations worth of images to fetch. Or if it worked fast enough you could fetch all the required images for the adjoining locations so they would be ready to go instantly. It depends entirely on no of image bytes per location. Yes, I looks like I'll be switching to a as-you-go-along-it-loads-the- next-rooms approach. Allthough... Point is doing it this way old images are thrown away and can be garbage collected as you go, so you are not accumulating images in memory. It's stable. (assuming I'm right about the how this works of course). ...I'm not sure there will be much that can be chucked away in this game. My engine is able to remove items easily enough, but for this game items from the start of the game are still usefull at the end, so theres only a few case's when images can be removed never to be recalled. . The point of the composite image strip is to fetch several images in one request since they come in a single binary file. Yes, I understand the point of them, and I think image bundles are a great idea. (In fact, online in general, theres probably a lot of wasted bandwidth used on little UI elements on webpages..like 5kb gifs etc) In this specific case though they arnt approperate. Not unless I got the server to dynamically splice the images together and the client to cut them up. But thats beyond the scope of the projects timeframe. This is exactly what the GWT ImageBundle does (and what has been best practice in web design for years). Annoyingly for you GWT only does this once per module because Bruce says they can't think of a single use case for needing separate ImageBundles! My bet is that if you just start loading all the images as you are suggesting, you will have to attach them to the DOM somewhere, so ultimately what you will be doing is building the entire game at the same time as the player is trying to play the first locations. So my betting is three to one on a) whilst this build is going on the game play will be badly affected at precisely the time you least want it to, and b) once you've loaded it all it will run like a dog anyway. Yes, I think your right there. But I think cutting up 30MB of images client side might actualy raise the required specs of the game :P I may well be wrong, but if I'm not, and you looked at the maze idea as plan B, then using image strips a la ImageBundle will make the game run much faster and smoother, so the effort might well be critical in the end. This is after all the heart of your technical challenge. This has been done so many times I expect you will find some javascript code that cuts them up (or maybe CSS stuff) to crib from somewhere and some server side tools to pack the image strips as well. I may have miss-understoof how image bundles worked completely here though, as I originaly thought they were fixed at compile-time. From the perspective of people editing the game content (images/text), what would they have to do? Run a script file of some sort every time they changed an image in the game? Or would the image be spliced together server-side for each user as they request the javascript? (which would surely increase sever load and load time too) I'm thinking strongly of going for the maze-techique now, but still need the best method/approach for loading within it. (Basicaly ; I know theres these 10 large images to be loaded for the next area, whats the best way to do it so the client dosnt notice the loading) --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Binary distributions are available for download directly from GWT's Google Code project. http://code.google.com/p/google-web-toolkit/downloads/list?can=1q=1.6.0 As always, milestone builds like this are use-at-your-own-risk. There are known bugs, and it definitely isn't ready for production use. Please expect some trial and error getting everything to work. The javadoc that comes bundled with the distribution should be up-to-date, but the online Developer Guide (http://code.google.com/docreader/#p=google-web-toolkit-doc-1-6) is still very much a work in progress. We will be updating it over the next several weeks. In lieu of an up-to-date Developer Guide and release notes, below are the major highlights relative to GWT 1.5.3. *** New Project Structure in GWT 1.6 *** One of the biggest changes to GWT 1.6 is a new project structure. The old output format has been replaced by the standard Java web app expanded war format, and the actual directory name does default to /war. Note that the war directory is not only for compiler output; it is also intended to contain handwritten static resources that you want to be included in your webapp alongside GWT modules (that is, things you'd want to version control). Please also note that the GWTShell and GWTCompiler tools will maintain their legacy behavior, but they have been deprecated in favor of new HostedMode and Compiler tools which use the new war output. When 1.6 is officially released, we will be encouraging existing projects to update to the new directory format and to use the new tools to take advantage of new features and for compatibility with future GWT releases. The sample projects provided in the GWT distribution provide an example of correct new project configurations. For more details on the specifics of the new project format, please see GWT 1.6 WAR design document ( http://code.google.com/p/google-web-toolkit/wiki/WAR_Design_1_6). A couple of important changes we should highlight here: - Projects with server-side code (GWT RPC) must configure a web.xml file at /war/WEB-INF/web.xml. This web.xml file must define and publish any servlets associated with the web application. See the included DynaTable sample. Additionally, server-side library dependencies must be copied into /war/WEB-INF/lib. For example, any GWT RPC servlets must have a copy of gwt-servlet.jar in this folder. - HTML host pages will no longer typically be located in a GWT module's public path. Instead, we'll be recommending that people take advantage of the natural web app behavior for serving static files by placing host pages anywhere in the war structure that makes sense. For exmaple, you might want to load a GWT module from a JSP page located in the root of your web app. To keep such handwritten static files separate from those produced by the GWT compiler, the latter will be placed into module-specific subdirectories. Any page that wishes to include a GWT module can do so via a script tag by referencing the GWT-produced module.nocache.js script within that module's subdirectory. As of 1.6, we'll be recommending that only module-specific resources used directly by GWT code, such as image files needed by widgets, should remain on the public path. See the included Showcase sample for some examples of this distinction. - When you do need to load resources from a module's public path, always construct an absolute URL by prepending GWT.getModuleBaseURL(). For example, 'GWT.getModuleBaseURL() + dir/file.ext'. This advice has not changed, but in the past it was easy to be sloppy with this, because the host page and GWT module typically lived in the same directory, so using a relative URL would usually do the right thing. Now that GWT modules live in a subdirectory, you must reference public resources through GWT.getModuleBaseURL(). *** Hosted Mode Enhancements *** Although the legacy GWTShell still uses an embedded Tomcat server, the new HostedMode runs Jetty instead. There is also a new Restart Server button on the main hosted mode window. Clicking this button restarts the internal Jetty server, which allows Java code changes to take effect on the server without having to completely exit and restart hosted mode. This is useful when making code changes to RPC servlets, or when serializable RPC types are modified and the server and client are out of sync. *** New EventHandler System *** Event handlers have been added to replace the old event listeners used by
[gwt-contrib] Re: Announcing GWT 1.6 Milestone 1
Hi, As a confidence test I tried to compile our projects with the new release and failed miserably. Is it expected that the GWT JavaScript compiler now seems to use native code ? Is this to support compiling in multiple processes ? Or is it a sideeffect of some other changes ? I normally build our final release builds on SunOS and we use the windows dev jar. Why do I do this ? Corperate BS forces me to access all sources on a clearcase filessystem (running on top of NFS) which is extremely slow. When I build on SunOS I can do it on the actual viewserver. I guess I have another reason to request snapshot views (which puts everything on a local disc instead) :-) David [echo] Invoking GWT JavaScript compiler.

[gwt-contrib] Re: Announcing GWT 1.6 Milestone 1
Congratulations! I'll try to give this a swing this week or next week, I hope it doesn't break the gwt-maven plugin too badly. Does anyone know when this milestone will hit the central Maven repo? -- Arthur Kalmenson On Wed, Feb 4, 2009 at 7:34 PM, Scott Blum sco...@google.com wrote: Greetings GWT developers, The GWT team is happy to announce the availability of 1.6 Milestone 1!

A couple of important changes we should highlight here: - Projects with server-side code (GWT RPC) must configure a web.xml file at /war/WEB-INF/web.xml. This web.xml file must define and publish any servlets associated with the web application. See the included DynaTable sample. Additionally, server-side library dependencies must be copied into /war/WEB-INF/lib. For example, any GWT RPC servlets must have a copy of gwt-servlet.jar in this folder. - HTML host pages will no longer typically be located in a GWT module's public path. Instead, we'll be recommending that people take advantage of the natural web app behavior for serving static files by placing host pages anywhere in the war structure that makes sense. For exmaple, you might want to load a GWT module from a JSP page located in the root of your web app. To keep such handwritten static files separate from those produced by the GWT compiler, the latter will be placed into module-specific subdirectories. Any page that wishes to include a GWT module can do so via a script tag by referencing the GWT-produced module.nocache.js script within that module's subdirectory. As of 1.6, we'll be recommending that only module-specific resources used directly by GWT code, such as image files needed by widgets, should remain on the public path. See the included Showcase sample for some examples of this distinction. - When you do need to load resources from a module's public path, always construct an absolute URL by prepending GWT.getModuleBaseURL(). For example, 'GWT.getModuleBaseURL() + dir/file.ext'. This advice has not changed, but in the past it was easy to be sloppy with this, because the host page and GWT module typically lived in the same directory, so using a relative URL would usually do the right thing. Now that GWT modules live in a subdirectory, you must reference public resources through GWT.getModuleBaseURL(). *** Hosted Mode Enhancements *** Although the legacy GWTShell still uses an embedded Tomcat server, the new HostedMode runs Jetty instead. There is also a new Restart Server button on the main hosted mode window. Clicking this button restarts the internal Jetty server, which allows Java code changes to take effect on the server without having to completely exit and restart hosted mode. This is useful when making code changes to RPC servlets, or when serializable RPC types are modified and the server and client are out of sync. *** New EventHandler System *** Event handlers have been added to replace the old event listeners used by Widgets, History, and various other classes. The new system has a few differences

Can you create a test case that is reproducible and add an issue to the issue tracker? After you do that, feel free to e-mail me the issue id and I'll take a look. The strange thing about your problem is that the load listeners are actually just adapted load handlers now, so getting different behavior is pretty unexpected.

[gwt-contrib] Re: Announcing GWT 1.6 Milestone 1
Nicolas, I can't reproduce the issue you're seeing. Do you have a weird
classloader setup? Or is it possible the code you have that references
About needs to be recompiled? Try the following test.. create a Main.java
in your GWT install directory and run the following commands.
Main.java:
import com.google.gwt.dev.About;
public class Main {
public static void main(String[] args) {
System.out.println(About.GWT_NAME);
System.out.println(About.GWT_SVNREV);
System.out.println(About.GWT_VERSION);
System.out.println(About.GWT_VERSION_NUM);
}
}
Command line:
C:\gwt-windows-1.6.0%JAVA_HOME%\bin\javac.exe -cp gwt-dev-windows.jar
Main.java
C:\gwt-windows-1.6.0%JAVA_HOME%\bin\java.exe -cp .;gwt-dev-windows.jar
Main
Google Web Toolkit
1...@4621m
Google Web Toolkit 1.6.0
1.6.0
C:\sandbox\gwt-windows-1.6.0
This seems correct to me.

I'm using About.GWT_VERSION_NUM constant in gwt-maven-plugin to detect the
