Google Wave UI GWT Sample
Hi, Google Wave UI which is designed using GWT look awesome. When will the client side code of Google Wave will be open sourced. I think it is nice Sample application of GWT and should be added to GWT samples. I think GWT-Mosiac has similar UI look and feel as Wave. But I would like to see how wave client is designed using GWT.

Re: Problem with Horizontal Panel
No, in that case you should use HorizontalSplitPanel.

Hello and Hello22 comes sides next to each other, shouldnt they be
separate by an horizontal spilit?

Hi,
I am not able to see the Horizontal Panel
this is my code
public void onModuleLoad() {
HorizontalPanel panel = new HorizontalPanel();
Label L1 = new Label();
Label L2 = new Label();
L1.setText(Hello);
L2.setText(Hello 22);
panel.add(L1);
panel.add(L2);
RootPanel root = RootPanel.get();
root.add(panel);
}
}
When i change horizontal Panel to horizontal shift panel its works,
but it does not works with horizontal panel
why is that?

Re: Determining a specific cell in a FlexTable
You can let each widget know it's position in the table by extending it with row and col properties. On 20 Jul., 16:37, jeffdonthemic j...@jeffdouglas.com wrote: I'm working on my first project using the FlexTable and am developing a time entry POC. Essentially users can click a button to add a new row to the entry screen, select a project for that row and then enter time for 7 days. I then total the 7 days for the line and then sum all of the lines for a grand total. Not rocket science. I'm using a few handlers to determine which cell and row the user is currently entering time for but it seems like a hack. Is there an easy way to determine which widget in the FlexTable (row x, column x) the user is currently interacting with? Thanks!

InfoWindowContent JavaScript Browsers
Hello NG!
i found something akward.
i am putting some data in a InfoWindow.
when i open this data in FF or IE all works fine.
as soon as i put it in the infowindow as InfoWindowContent
IE stops executing the JavaScript.
i even tried with the most simple JS around...
script type=text/javascriptalert('OK');/script
note that FF executes ALL javascripts correct! but this will not help,
as also IE has to work on the page...
note that IE also throws:

which is gmaps api - probably this stops the scripts from working -
afaik ie stops executing JS after an error...
hope someone can solve this with me.
thanks in advance

RE: Automatic Testing
Hello Dan! Thanks for the answer! I think that right now what we need is a simple end-to-end smoke test. Witch of WebDriver or Selenium would you think is the best way to go? Do you know if any of them have the possibilities of getting an xml file with data to enter during the testing to run the test with? How does the ensureDebugId work? Is that something you add in your GWT application?

Re: GWT Toolkit Problem
In addition to this.
I have just tried the very same code on my laptop with GWT SDK 1.6.4
and Google Plugin for Eclipse 3.4 and it works fine.
So.. .i uninstalled GWT on my problematic machine. Opened the
workspace with the -clean command. Reinstalled GWT SDK and Plugin
(didnt install the app engine this time as i dont think i need it). I
then ran the same code i created the previous day and that failed
again ahh!!
So, i deleted all my code.. .deleted the workspace and started again
with the sample app. Didnt include the App Engine when creating the
GWT Application. Recreated the same code.. and...
hey presto it now works.
Very confused but i guess my previous attempt at the demo copied some
jar files into the WEB-INF/lib direcotry that werent quite right.
Anyway.. onwards and upwards..
So i think for now.. i am ok..
Will keep you posted.
Thanks again for your help.

Re: InfoWindowContent JavaScript Browsers
Hi lumo,
My guess is that your code is passing 'null' into a Maps API method.
Which method, we cannot tell because we have neither code from your
project, nor a stack trace from hosted mode. Have you tried using
hosted mode along with a JavaScript debugger? That will get to the
bottom of this in a jiffy.

Re: GAE + GWT + password transfer
For what you're doing and the limitations you have mentioned, I would go with OpenID, that way you rely on third parties to do the authentication, and I think in most cases it will use https. I have used Spring Security to quickly setup openID as an authentication method (although I have never run within appspot, so can't help with specifics for your case).

I'm not from a Web background (C++ + video games), so this may be painfully obvious, but I want to know how people authenticate over non- HTTPS connections, specifically using GAE (Java). My point is that any app that stores any sort of user specific data will need the user to log into their app. I've had a look around at various public sites, and watched the data going back and forth over the wire, and the results are surprising. A lot of public sites use basic auth over http, which surprises me. As I mention above, even Twitter doesn't use HTTPS in its default state for users loggin in, and same goes for their REST API. So, what do people do? I am going to look into OpenID and OAuth next. Cheers, Shane On Jun 13, 12:57 am, Isaac Truett itru...@gmail.com wrote: I'm not sure what your question is.

Re: Automatic Testing
Joakim, Either tool should work. If you try out Selenium, you'll need to try out the Selenium RC version, which lets you write your tests in Java, Ruby, Python, etc. WebDriver lets you write your tests in Java. I'd probably use WebDriver if I had to start a new project today - parts of it are getting merged into the next version of Selenium. http://google-opensource.blogspot.com/2009/05/introducing-webdriver.html Since you'll be writing your tests in a programming language like Java, you can do whatever you want with input XML files, but it will be up to you to parse the files just like you would in any other program. As for ensureDebugId, the JavaDoc for UIObject has some documentation about how to use it. http://google-web-toolkit.googlecode.com/svn/javadoc/1.6/com/google/gwt/user/client/ui/UIObject.html#ensureDebugId(java.lang.String) Good luck!

GWT XMLParser converting element names to lowercase?
Hi all, I'm using the GWT XMLParser as described here: http://code.google.com/p/bunsenandbeaker/wiki/DevGuideXML I have to use it this way as I send a response string back from a form submission. However the parser seems to be converting all the element names to lowercase? This is makes it un-usable as we hoped to be able to alter the xml doc and then send it on again. But this means that is fails the XSD validation on the server side as the elements names do not match (case senstive). And all our server parsing methods retrieve the elements using the sentence case names as well! Has anyone else experienced this?

I personally don't see a need to split up this group. GWT is specific enough to have this group as it is.

Re: which panel should i use
A few ways to do it, depending on how flexible you want to be able to put data in/change it/ You could, for example, just use a simple grid widget (2 x However many rows you need). Then setting contents at particularly cells is easy. Or, you could use a horizontal panel containing two vertical panels. (Adding new entrys to specific sides is then as easy as just adding new items to the left or right panel). Or you could use a vertical panel filled with lots of horizontal panels.each horizontal panel containing a label and tab index. You could even make a new object for that horizontal sub-panel.

Generators don't work good with refresh button
Hi. The generators are without a doubt a remarkable feature of gwt. But if you use any reflection on the client classes in the generator you lose refresh button support. Furthermore while not that major I do find it annoying that refreshing doesn't recompile the generator code. You have to stop the hosted mode and start again. It all boils down to the fact that client code is loaded in ComplingClassLoader and the Generator is loaded in a different ClassLoader than that. Reflection is not that nice. But sometimes one has perfectly legitimate use cases to use reflection. A good example is Google-Gin. It came up here http://groups.google.com/group/google-gin/browse_thread/thread/d383babb48a287bb . Basically gin is instantiating the gin modules which are client code. If you change the module refresh doesn't work since gin generator is still seeing the original module loaded and not the recompiled. I've partially solved the issue (renaming modules doesn't work) by hacking into the byte[] definitions for the newly created code. Like this http://pastie.org/553279 . I guess JavaRebel could be used or something like that. But I'd like to see a pure gwt solution to this. I've been thinking in the lines of compiling the generators and putting the generators in a child of CompilingClassLoader. In that case using reflection in the generators should get the latest class definitions. Also changing generator code and pressing refresh would work. What do you guys think?

Re: ListBox CSS
Try adding a large z-index number to your CSS style like
z-index: 1000;
and report back.

I have 2 seperate problems although im sure there related.
Firstly i have a greyout panel (custom made), that is added to the

css style:
.panel-GlassPanel {
background-color: black;
filter:alpha(opacity=50); /** 50% is hardcoded in fade */
-moz-opacity:.50;
opacity:.50;
}
This works perfectly for all elements apart from ListBox which stays
the same colour as it was previously.
Secondly i have a popup that im fading out by using a timer to slowly
decrease the opacity. again, works great, apart from the list box
which isnt faded at all! any ideas why?
Im adding the ListBox to a grid on the PopupPanel like so:
listBox = new ListBox(true);
grid.setWidget(0, 0, new Label(Roles: ));
grid.setWidget(0, 1, dropBox);
Its like it has styles that are unnessacerily overriding its parent
elements. (i say unnessacery but perhaps theres a good reason?)
Thanks in advance,

Client source, what's included, what's not
How does the compiler/deployer know what source code is to be xcompiled into JS for and shipped to the browser and what not in Ecipse? More specifically I would like src/com..myproj.clientto be included but... srctest/com..myproj.client not. Is there a way of doing that?

Re: GWT XMLParser converting element names to lowercase?
I've used it but I didn't mind this client conversion. Think that gwt-xml parser delegates xml handling to the browser's native xml processing, so the behavior can be different in different browsers, and could be browsers converting to lowercase and not. So I suggest you to filter the xml document sent by the client in the server side before validating it.

Re: map, add marker and remove marker
Hi Again, I looked around and couldn't find 'removeAllMarkers' in either openlayers.Map or in Ext.ux.GMapPanel, so to figure out exactly how they implemented those with the Google Maps API, you'll have to look at the source where you got your distribution from. One thing you can look at is to make sure you are using a recent version of the maps API. In the URL where you load the Maps API script, check the version. If you are currently using v=2 try v=2.x. More info about the version number: http://code.google.com/apis/maps/documentation/index.html#API_Updates If you want to avoid memory leaks, one thing you can do is to not create and destroy markers, but instead re-use them. You can just hide them or move them off the map when you aren't using one. An example of re-using the markers in raw javascript is here under comment #15: http://code.google.com/p/gmaps-api-issues/issues/detail?id=945 -Eric.

Re: GWT XMLParser converting element names to lowercase?
Hi Manolo, Actually I think the problem may be due to the HTML form response rather than the XML parser. Our system works by using a FormPanel with a FileUpload object to upload a zip file to a servlet. The servlet then processes this and creates an XML file detailing the zip file contents. The FormHandler - onSubmitComplete(FormSubmitCompleteEvent event) listener receives the XML string response from the servlet. However the problem is the FormSubmitCompleteEvent will only accept content that is of MIME type text/html - it returns null if you try to send back text/xml or application/xml. So I think that as it is text/html being returned by the servlet it is all being converted to lowercase as html is case-insensitive. Does anyone have any other way to submit a zip file to a servlet and return an XML string?

I tried to use agwtfileupload widget to send a csv file to the

it by doing : (where request is the httpservletrequest and bw is the

BufferedReader r = request.getReader();

bw.write(thisread);
}
bw.close();

data; name=uploadFormElement; filename=first.csvContent-Type:
application/octet-streamBank
which results in the file created not the same as the fileupload.
I might be wrong in my analysis. can someone advice me?

Re: JSNI issues

still possible that part (2) is executing after your GWT code, and
hence it is not available to your GWT code when it runs. You could
wrap that code in it's own file and load through the script tag

I'd also suggest you use some debugging tools (Firebug for example in

Re: large GWT app fails to load in IE - anyone else seeing this?
Hi Dave, We have experienced some issues that may be explained by this. Did you get any further with fixing the issue? Joe On Jun 5, 7:20 pm, DaveS dave.sell...@gmail.com wrote: [re-post with better title - sorry for the dup but this is killing me!] If anyone from theGWTdev team is reading, please get in touch, we are struggling badly with this issue and would *really* appreciate any help. We have a fairly bigGWTapp, and we are experiencing some issues when running it in IE. Sometimes (and there's no rhyme or reason to it) the app simply fails to start up. The HTML file is loaded by the browser, and the my.app.nocache.js file is loaded, but it then gets stuck. After a *lot* of debugging and cursing IE, we found out that it is stuck in the .nocache.js file waiting for the document readyState to become ready. There is a timer-function in this file, that goes off every 50ms, and checks to see if the $doc.readyState is loaded or complete and for some reason, when our app fails to load, the $doc.readyState never has either of those values (it seems to be stuck in interactive). When the app loads and runs correctly, this timer finds the readyState the first time it goes off, and it then triggers the app to be loaded. I see there is also an event-listener on the DOMContentLoaded event that effectively does the same thing, so it looks like the designers tried to work around this in more ways than one already. Obviously, in the cases where our app fails to start, this event is not firing either. Has anyone else ever seen this, or have any ideas about why IE is not setting the document readyState. I can see it might be because the document really isn't ready, but is there any way we can tell what it's waiting for?

Running Hosted Mode for Front End and another J2EE container for Backend.
I am using Rational Application Developer 7, with GWT 1.7 plugin. I have ran through the sample application with no probs. I then created a Dynamic web project which organises things a little different from the default GWT project creator and imported all the StockWactcher code.. This all works fine. I then wish to add JPA for my persistence layer to the WAR project. I have added the necessary jar files to my lib directory and this works great when i complile and run it on my built in WebSphere 7 test environment. Unforunately it fails when i'm running it in hosted mode. I am guessing this is because my JPA configuration file (persistence.xml) specifies java:comp/env/jdbcName which is configured neatly on Websphere but i dont know how to do this on the tomcat version running in hosted mode. At the moment this leaves me with the problem that i can run the front end in hosted mode.. and debug it... but the backend integgration fails. or I can run it in my WAS test environment which allows me to debug the backend but not the gui because this is running compiled GWT code. Therefore i saw an old thread about runnign the front end in hosted mode and the backend using another J2EE container. Have you been able to do this with WebSphere. I suppose all i really want to do is change the url that the client is calling to access my remote service. At the moment i use the @RemoteServiceRelativePath(stockPrices) tag, which is relative.. but i would like to be able to specify a different port.. maybe even a different host. for example hosted mode uses http://localhost:8080/StockWatcher.html but i would like to tell it to point to http://localhost:9081/StockWatcher/stockwatcher/stockService for the remote service. This would allow me to debug both all neatly in my test enviromnet. I could probably do this by installing Apache Http Server and create a Proxy but would like to run it all from my test enviroment.

Re: GWT XMLParser converting element names to lowercase?
Hi Thomas, Thanks for your suggestions, I've used the xmp tag and the DIV trick and it now works a treat! Thanks for your help -Stu On Jul 21, 3:07 pm, Thomas Broyer t.bro...@gmail.com wrote: On 21 juil, 15:47, Stuart_L stuart.coo...@gmail.com wrote: Hi Manolo, Actually I think the problem may be due to the HTML form response rather than the XML parser. Our system works by using a FormPanel with a FileUpload object to upload a zip file to a servlet. The servlet then processes this and creates an XML file detailing the zip file contents. The FormHandler - onSubmitComplete(FormSubmitCompleteEvent event) listener receives the XML string response from the servlet. However the problem is the FormSubmitCompleteEvent will only accept content that is of MIME type text/html - it returns null if you try to send back text/xml or application/xml. So I think that as it is text/html being returned by the servlet it is all being converted to lowercase as html is case-insensitive. Right, if you just send XML labeled as being text/html, it'll be parsed as HTML and then the FormPanel will re-serialize it with the help of the innerHTML property. Does anyone have any other way to submit a zip file to a servlet and return an XML string? You can try two things (amongst probably many others): - prefix your XML with plaintext or wrap it within xmp (they are roughly equivalent to ![CDATA[]] in the text/html world) and of course account for it when parsing with XMLParser - HTML-escape your XML (i.e. lt; instead of and amp; instead of ) before sending it to the browser, that way it won't be parsed as HTML markup, but you'll have to un-escape it on the client side; to unescape, in your GWT code, you can create a dummy DIV element, set the form's result with setInnerHTML and get it back with getInnerText (or just do string replacements of amp; and lt;, but in my opinion the setInnerHTML/getInnerText is more robust re. non-Windows-1252 characters, which the browser might convert into character references when serializing using innerHTML) ...of course, it's far easier to just not use square brackets and ampersands in your response... (e.g. JSON with \u-escaped and ), and do not count too much on whitespace being preserved too. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: JSNI issues
.perhaps you have the Javascript library in the wrong place and it
is not being loaded. I'd still suggest you get hold of a debug tool
in your browser to see what's loaded etc as you're going to need it
when you get into trying to access the library and going further, but,
the following works for me to access the library.
1. In my applications .gwt.xml file I have put: script src=protovis-
r2.6.js/
2. I also have defined my module in the .gwt.xml file as follows:
module rename-to='testAA'
3. I'm using GWT1.6, so the protovis-r2.6.js file needs to go in
within the war file, i.e. it goes in the folder /war/testAA/
4. In my application I just create a simple JSNI method
public native JavaScriptObject getVis()/*-{
var vis = new $wnd.pv.Panel().canvas(test);
return vis;
}-*/;
5. In my onModuleLoad I simply call the method and alert the fact
that I have an object
public void onModuleLoad() {
JavaScriptObject v = getVis();
Window.alert(v.toString());
}
that tells me I have got a valid JavaScript object and I see no
exceptions or errors.
Hope that helps, or at least gives you some hints.

Re: Accessing ActiveX from GWT code
Hi Gugi, You can interact with your ActiveX object in GWT code the same way you would access it through regular JavaScript. This can be accomplished by using the JavaScript Native Interface feature available in GWT. Using JSNI, you can write native methods implemented in regular handwritten JavaScript. There are a few catches to be wary about, such as the fact that the 'window' variable must actually be referenced through the '$wnd' variable in JSNI code, but other than that, JSNI is straightforward to use. Check out the documentation linked below for more details. JavaScript Native Interface: http://code.google.com/webtoolkit/doc/1.6/DevGuideCodingBasics.html#DevGuideJavaScriptNativeInterface Hope that helps, -Sumit Chandel On Thu, Jul 16, 2009 at 10:46 PM, Gugi vsbgu...@gmail.com wrote: Is it possible to access the ActiveX object( using JavaScript) inside a GWT client code.

Re: Annotations in GWT
Hi Gian,
The reason why your code snippet fails at Line 37 is because GWT doesn't
support / emulate the Class.getAnnotation() or isAnnotationPresent()
methods. Although GWT does support the use of annotations, which is useful
for cases where you would like to reuse a POJO on both the client and the
server-side. However, supporting something like getAnnotation() in GWT code
wouldn't be as useful since there wouldn't be a lean equivalent of that in
the target JavaScript world.
You can check out more details about the GWT Emulated JRE to see the types
and methods that are supported at the link below.

Re: Running Hosted Mode for Front End and another J2EE container for Backend.
Hi All. sorry.. i guess i was looking at a very old thread. I have just discovered the -noserver option which i think does exactly what i want. On Jul 21, 4:25 pm, JonJ27 jon...@gmail.com wrote: I am using Rational Application Developer 7, with GWT 1.7 plugin. I have ran through the sample application with no probs. I then created a Dynamic web project which organises things a little different from the default GWT project creator and imported all the StockWactcher code.. This all works fine. I then wish to add JPA for my persistence layer to the WAR project. I have added the necessary jar files to my lib directory and this works great when i complile and run it on my built in WebSphere 7 test environment. Unforunately it fails when i'm running it in hosted mode. I am guessing this is because my JPA configuration file (persistence.xml) specifies java:comp/env/jdbcName which is configured neatly on Websphere but i dont know how to do this on the tomcat version running in hosted mode. At the moment this leaves me with the problem that i can run the front end in hosted mode.. and debug it... but the backend integgration fails. or I can run it in my WAS test environment which allows me to debug the backend but not the gui because this is running compiled GWT code. Therefore i saw an old thread about runnign the front end in hosted mode and the backend using another J2EE container. Have you been able to do this with WebSphere. I suppose all i really want to do is change the url that the client is calling to access my remote service. At the moment i use the @RemoteServiceRelativePath(stockPrices) tag, which is relative.. but i would like to be able to specify a different port.. maybe even a different host. for example hosted mode useshttp://localhost:8080/StockWatcher.html but i would like to tell it to point tohttp://localhost:9081/StockWatcher/stockwatcher/stockService for the remote service. This would allow me to debug both all neatly in my test enviromnet. I could probably do this by installing Apache Http Server and create a Proxy but would like to run it all from my test enviroment.

Re: Handling Multiple Click Events
It works actually. I just tried it :) What's the error you're getting?
Hm, while I haven't played much with the event handlers in GWT yet, I think
a better approach might be to implement the ClickHandler interface and
attach the same object to all the buttons rather than creating new objects
for an array of buttons.

How to test GWT MapWidget?

using JUnit4 only instead of using GWTTestCase.
I´ve trying to create a simple application using the GWT Google Maps
API,
but i´m having trobles writing tests for my presenter.
The presenter, somewhat stripped, looks like this:
public class MapDisplayPresenter {
HandlerManager eventBus;
MapDisplayInterface widget;
MapData data;
public MapDisplayPresenter(MapDisplayInterface mapDisplayWidget,
MapData data,
HandlerManager eventBus) {
this.data = data;
this.eventBus = eventBus;
this.bindDisplay(mapDisplayWidget);
}
private void bindDisplay(final MapDisplayInterface widget) {
this.widget = widget;
widget.getMap().addMapClickHandler(new MapClickHandler() {
public void onClick(MapClickEvent event) {
widget.getMap().addOverlay(new
Marker(event.getLatLng()));
}
});
}
interface MapDisplayInterface {
HasClickHandlers getButton();
MapWidget getMap();
HasText getTextBox();
ListBox getList();
}
}
Since the MapWidget doesn´t implement alot of interfaces, I couldn´t
find a good way to access the MapWidget
without exposing the entire object instance through my
MapDisplayInterface.
The problem comes when I try writing tests for this presenter.
I tried using JUnit, extending it iwth Jmock, further extending it
using JDaves unfinalizer,
but sooner or later, the MapWidget or one of it´s subclasses throws an
exception.
So are there any good ways of writing tests here without using
GWTTestCase?
Are there any better ways of implementing my own interface that doesn
´t involve exposing
the entire MapWidget?
Would Selenium (which I have never used) be a better idea?

Re: ClassCastException only in Chrome and OBF mode
Do you know which RPC methods trigger it? Is it all RPC methods or just some/one? Can you use some log statements to narrow this down? Does this suggest the problem exists in GWT code or your own code? Can you produce some simpler example code that still shows the problem? Has the problem just arisen, and if so, what's changed lately? Can you roll back to an earlier version of your code to see if the problem goes away? If so, which change made the problem arise? You could try it in safari 3.x, but that may not tell you much. mars1412 wrote: it doesn't occur in hosted mode - my hosted mode browser is IE6 - unfortunately we must still use GWT 1.5.2 and there's no OOPHM available ah - yeah - maybe I should mention some versions: * GWT 1.5.2 (I'll try to upgrade to 1.5.3 soon) * Chrome 2.0.172.37 * app does not work in safari 4.0.2 at all (this is due to some java- script limitation - GWT fix for this exists in GWT 1.7 AFAIK) On 21 Jul., 18:44, Jason Essington jason.essing...@gmail.com wrote: Uhm hosted mode is IE, FF, or Safari depending upon the platform ...

Re: eclipse + gwt + getting started = Syntax error, annotations are only available if source level is 1.5

Profiling memory usage for large gwt application
hi We are using the gwt 2.0 code from gwt trunk.And we hav seen a drastic improvement in the page loading especially in case of IE(6 and 7).Actully breaking the compiled code into the multiple script tag did the trick. But now we are facing the browser memory problem.Actully our total compiled script size(in OBF mode) is more than 3 MB.As we use the application the browser memory keeps on increasing and sometimes it even reached to the 700MB. We tried to profile the application using the javascript tool(like firebug) but of no use because the only provides the performance metrics and not any memory leaks. Now we are trying to profile the gwt in the OOPHM mode while debugging.Its helpful and we are able to find some of the problems in our code.But actully during debugging time most of the refrences are held by gwt code(mainly by JavaDispatchImpl class and by the static variable in RootPanel i.e. widgetstoDetach) and also all the asynccall backs are held by RequestBuilder. We are assuming that these refrences wont be hold in the compiled mode,because all the classes we see are the debugger classes.But its making that profiling very tedious as we need to search what refrences are held by the gwt and where our classes are keeping refrence. I dont know we are going through correct approch fpr profiling or is there any other way so that we can check all the memory leaks and reduce the memory footprint of our application in the browser. Any help in this heartly welcomed.And also if we can reduce the objects (especially all the RPCs callbacks) then actully we can reduce the meomory used during debugging and it might help in mking it faster. regards ankur --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Is there a way to force serialization of a Class ?
Hi AymenS, You could manually enter the class name that you want to serialize to the generated serialization policy file (for example, as part of your build process). You can take a look at the generated serialization file to see an example of the format required to add the exception type to the serialization policy (essentially pairs of fully qualified classnames and booleans indicating whether the type can be instantiated). However, it's important to note that allowing a Hibernate exception to bubble up to the client-side is generally bad practice. Instead, you should catch the exception on the server-side and either delegate the exception to something specific and friendlier to the GWT client-side that can be used to handle the error elegantly on the client or provide some kind of error signaling in the RPC callback between the client and the server. Hope that helps, -Sumit Chandel On Fri, Jul 17, 2009 at 8:29 AM, AymenS sayhi.ay...@gmail.com wrote: What I know in GWT serialization is that only classes that are mentionned (params, return type) in RPC methods are included in GWT serialization policy white-list.

Interface not RPC serializable
I'm trying to RPC-send an interface member in a POJO - all types
implementing this interface are Enums (see the example below please).
Now, the application works 100% in both hosted and web modes, but the
Java to JavaScript compiler complains about the POJO object, that the
MyIFace is not RPC-serializable. (was not serializable and has no
concrete serializable subtypes)
Any ideas how to get rid of that compiler warning? I'm using GWT 1.6
for the time being.
class POJO { //this object is sent via the RPC
MyIface iface;
}
interface MyIface extends IsSerializable {
MyIface[] getVals(String param);
}
enum MyEnum implements MyIface {
one(1),
two(2);
private MyEnum(String s) { this.s = s; }
private MyEnum() { }
private String s;
MyIface[] getVals(String param) {
return MyEnum.values();
}
}

Re: Command Pattern, MVP, EventBus
About the gwt-presenter library, I found some points that I would like talk to you: - When I extend WidgetPresenter/BasicPresenter I have to implement many abstract methods, is it really necessary to set those methods as abstract? Isn't it better to provide an empty default implementation? I know that I can do it by myself but it's just a suggestion. - Isn't it better to define the Place mechanism in the BasicPresenter checking if the current object is a instanceof SomePlaceInterface instead of calling directly getPlace? - I didn't realize the meaning of the startProcessing and stopProcessing methods in Display interface. Can you gimme some usage example? That's my 5cents, I think I will change my project to use your library and keep it online just as an usage example.

Yes I've been thinking about that. Any user action that interacts with the server: sign in, create account, update address, etc., has an asynchronous response. I find myself tempted to wrap the service request in and make it synchronous but that would be morally wrong and lead into all kinds of difficulties in the details. So I've gone the other route... My proof of concept implementation treats a click on the 'sign in' button as an event which it fires and forgets to the event bug. Maybe this goes too far in the other direction - time will tell.

Re: Image Bundle not working in IE
If I understand you correctly, what I did was go into Run Configurations and turned off Run built-in server. Then use the browser that comes up to goto my deployed site on my external server? Well, I tried that and I got: [ERROR] Unable to find 'celticlock.gwt.xml' on your classpath; could be a typo, or maybe you forgot to include a classpath entry for source? But, then I tried to goto the GWT Showcase and I got the same thing: [ERROR] Unable to find 'showcase.gwt.xml' on your classpath; could be a typo, or maybe you forgot to include a classpath entry for source?

Getting a simple GWT project to gwt-compile in maven2
Hi,
I am trying to get a very simple GWT project to gwt-compile using the
codehaus' maven-gwt plugin but I don't seem to be having much
success...
The project is nothing more than a regular starter GWT 1.7 (same as
1.6 plus bug fixes) Eclipse GWT plugin project. All I did after
creating a new project in Eclipse with the GWT Eclipse plugin was to
create main/java under the src directory and put that into the class
path instead of just the default src directory.
My pom.xml is shown below. When I do 'mvn clean compile', I see that
GWT compile gets kicked off, but when I go the exploded built WAR and
double click on the host HTML page, it tells me GWT module
'szblankweb' needs to be (re)compiled, please run a compile or use the
Compile/Browse button in hosted mode. Same thing happens if I deploy
the .war file into a container.
If I run the app inside Eclipse in hosted mode and then do 'mvn
package' (without the clean), everything works.
Any idea of what I am not doing or doing wrong here?
Here is my pom.xml:

user agent compiling help
With the release of GWT 1.7 I know have 6 permutations compiling, and since I have a very targeted audience, I don't need them all. I found I can change the targets by using something like this in my module xml file: set-property name=user.agent value=ie8,gecko,safari/ Will this target the latest releases of these browsers? If not, which values should I be using to make this happen? Can I get a user agent to browser mapping? And I assume that chrome uses safari? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Interface not RPC serializable
Yeah I've left that out in the example, it of course is marked with
IsSerializable.
However! - I've found a solution (just needed to recall that I've had
similar problem with Interfaces+Classes already):
A Class (or Enum) type extending the said non-serializable interface
(MyIface in the above example) needs to be defined in the same package
as the interface. The compiler warning is then not produced.
I've scanned GWT-Issues (and GWT docs) for this, haven't exactly found
it - should I fill this as an Issue?

Re: Client source, what's included, what's not
hello, it's all about the source directive in the gwt app XML file. GWT compiles source code to JS when the source directive point to it. if you specify no source directive, GWT will compile the 'client' package to JS. example: source path='client' / source path='shared' / these two packages and all their subpackages will be compiled to JS.

Re: Image Bundle not working in IE
As a quick Test, I made a GWT App that was just a Tree with one item added to the RootPanel. No +/- in IE. Atleast I know it's not something in my huge app. I also set my IE settings for intranet pages to Medium_high which the web setting is, and I still see everything fine on the local machine. Since I see everything fine in IE on my local machine as well as Google's Showcase website, I can only think it's something with my server. Now...how the hell to figure that out? That I have no clue. Nothing off in the logs, the java script should work just the same everywhere. So confusing. It's Mocha hosting, so it's a reputable place. I can't understand how the .js being read from there would do something different then on my local machine.

Re: GWT project runs slow in Hosted mode
Hi Dorothy, Most of the cases reported on this thread involved using multiple GWT libraries along with GWT core itself. As Jason suggested above, it's possible that one of the reasons for the slowdown is many Java to JS boundary crossings in the associated libraries. I'm not familiar with GWTX, but you may want to check out some of its implementation details to see if it is also making a lot of Java to JS jumps through JSNI bindings. Depending what your application does when it first loads up (the GWT module itself and any third party libraries), there may also be a culprit responsible for slowdowns there. Another thing to check would be how many logs are being generated when your start up your application and its 4 modules in hosted mode. It's possible that these are causing considerable slowdown if the logLevel parameter is set in your launch configuration. If this is the case, try omitting the -logLevel DEBUG flag in your launch configuration to see if that speeds things up. Hope that helps, -Sumit Chandel On Sat, Jul 18, 2009 at 12:25 PM, Dorothy dgantenb...@comcast.net wrote: We are having the same issue upgrading from 1.5 to 1.7. For our application, we have GWTX in addition to the GWT. For our project, we have 4 GWT modules that are in development. For hosted browser with the -noserver option, our launch time in 1.5 was ~90 seconds and is now over 10 minutes in GWT 1.7. Some initial investigation indicates that removing our public resources gives a modest improvement but nowhere close to GWT 1.5 times.

How to deal with multiple coordinating RequestBuilder sends?
Hi there, I'm a newb when it comes to GWT so I need your advice. I have a situation where I am making two restful calls using RequestBuilder R1, R2. R1- http://localhost:8080/universe R2- http://localhost:8080/someDataContainedInUniverse I have two ListBox components L1, L2 where data in (R1-R2) is put into L1, and data in R2 is put into L2. How can I wait on the result of some request so I can ensure that the underlying ListBox components contain the proper information in the correct state. I realize R1 and R2 make asynchronous requests so their callbacks can happen at any time. What will happen when they do since they both need to coordinate/communicate the same underlying ListBox.

Then, I added that services project to another project's build path (let's call the other project index) and added the following line to the Index.gwt.xml inherits name='myproject.Services'/.
