Facing some problems after switching to GWT 2.1 from GWT 2.0.4
Hi,
I have updated my GWT version to 2.1 and faced some of the problems
regarding textbox' key press handlers...
the code which works completely fine in previous version is
txtPassword.addKeyPressHandler(new
KeyPressHandler() {
@Override
public void onKeyPress(KeyPressEvent event) {
if(event.getCharCode()==KeyCodes.KEY_ENTER){
// some processing here to send
username password to server
}
// class closures.
whenever user presses an ENTER key the code from 'if' condition gets
executed but this does nt work in GWT 2.1
is there any other way to perform this validation to know user has
striked ENTER or not...?
Thanks,
Aditya

GWT MVP How to change Page title upon Navigation (Place Change)
traditionally apps have been composed of pages of HTML. title of each HTML page could be set through HTML tag . in GWT apps, generally there is one main html file. as user navigates throughout the app, URL (history token) changes, however I can't seem to figure out how we can change the Page Title. I understand everything is one Page, and GWT apps doesnt fall into traditional web apps. But I'm wondering if there is a way to set the page title, so that it can be displayed at browser header. -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Understanding of GWT Upload
Hi All, I have a requirement where I have to support upload of around 500MB files (zip file), so wanted to understand how GWTUpload work: 1) Does it chunk the data, or it sends the data as a continuous stream and keep it in memory ? If yes then it would lead to out-of-memory. 2) Is it a reliable library for uploading huge data. If this does not support, then are there any other libraries that would support ? Any help would be greatly appreciated. Thanks, Snehil Parekh. -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: MVP *without* UiBinder
Thank you Konstantin,
The open with "Windows Builder Editor" did the trick. I can now edit
the gui graphically and easily work with event handlers without
jumping between two files.

Multi Reference Object Graph - How to Persist.
Hi,
I have a case where I have an object
class ObjectFoo {
private ObjectFoo next;
private ObjectFoo previous;
}
These Objects get stored in a parent object as a set
class Parent {
private Set foos;
}
when I work with a particular object I am having difficulty "updating
the tree", and just wanting to know How I can properly populate an
ObejctFoo with other previously persisted ObjectFoo's ?
Attempt A. - Set the next and previous on all objects and store.
problem: it recurses the object graph going between one and two and
then stack overflows (on the server).
ParentRequest req= getRequestFactory().parentRequest();
ObjectFooProxy one = req.create(ObjectFooProxy .class);
ParentProxy editableParent = req.edit(parent);
ObjectFooProxy editabletwo = req.edit(two);
one.setNext(editabletwo );
editabletwo.setPrevious(one); // previously created
editableParent.getFoos().add(one);
req.persist().using(editableParent).fire();
Will try (somehow) .. :
create and store (one).
on success of entityproxyChange event, ** edit two and set the
reference to one.
BUT.. how do I, after persisting One, retrieve the new copy of it ?
a. can I get it out of the RequestFactory, or do I have to query it
up ?
b. can I use the EntityProxyChange event ? if so, How will I
recognise it is "my" ObjectFoo{one} that comes back ?
any ideas ? (do I need to clarify the problem ? )

The trick is that the AcceptsOneWidget that you use for your ActivityManager has to handle a 'null' value as *not* clearing the display (in other words, give an AcceptsOneWidget of your own, do not use a SimplePanel). ActivityManager calls setWidget(null) when it stops the current activity, and the next activity will then call setWidget with its view when it's ready. If, when called with null, you don't do anything, the previous activity will still be shown. And in your activities then only call setWidget once you received the data.

Custom widget is blocking all events.
I've got a simple custom widget designed to display two column data.
Any widgets I put in this custom widget can't fire events. I've tried
even the simplest Button and it fails. Is there something about the
nature of my widget that is keeping events from widgets it contains
from firing?
public class LabeledValueWidget extends Composite {
private String caption;
private Map items = null;
private CaptionPanel container = new CaptionPanel();
private Style style;
static boolean isInjected = false;
public LabeledValueWidget () {
this.initWidget(container);
}
public void setItems (Map items) {
this.items = items;
}
@Override
public void setStyleName (String styleName) {
super.setStyleName(styleName);
}
@Override
public void addStyleName (String styleName) {
super.addStyleName(styleName);
}
public void setCaption (String caption) {
this.caption = caption;
}
public void render() {
style = LabeledValueWidgetResource.INSTANCE.style();
if (!isInjected) {
isInjected = style.ensureInjected();
}
container.setCaptionText(caption);
Element dl = DOM.createElement("dl");
writeDefinitions (dl);
container.getElement().appendChild(dl);
}
public LabeledValueWidget (Map items, String caption)
{
this.initWidget(container);
this.items = items;
render();
}
private void writeDefinitions (Element dl) {
for (Widget key: items.keySet()) {
Element dt = DOM.createElement("dt");
dt.addClassName(style.label());
dl.appendChild(dt);
Element label = DOM.createElement("label");
dt.appendChild(label);
label.appendChild(key.getElement());
Element dd = DOM.createElement("dd");
dd.addClassName(style.value());
dl.appendChild(dd);
dd.appendChild(items.get(key).getElement());
}
}
When I instantiate this and call setItems and pass it a map with
Label, Button and I've defined the button to have a click handler. The
click handler never gets fired ;(

I thought I had a solution when I found @eval but it *only* works with methods?
my.css
@eval BORDER_WIDTH org.example.MyCss.BORDER_WIDTH_PX;
interface MyCss extends CssResource {
int BORDER_WIDTH = 1;
String BORDER_WIDTH_PX = String.valueOf(BORDER_WIDTH) + "px";
}
This throws an exception. BORDER_WIDTH_PX *must* be a static method?

Re: HelloMVP sample with JUnit TestCase example?

HelloMVP sample with JUnit TestCase example?
I am new to GWT development and have written a simple app based upon the HelloMVP sample. I was drawn to this model for A) MVP design with code/UI separation, B) simpler unit testing not requiring GWTTestCase. My Activity class is somewhat more involved than the sample program, but not hugely. Most examples that I have seen use EasyMock - so I am trying to use EasyMock 3.0. However, I have not been able to get a single test case to compile and run successfully. Attempts to declare a variable of type IMocksControl or IMockBuilder give me the following error: "org.easymock.IMocksControl can not be found in source packages" (why is the source needed for a JUnit test that is supposed to be run outside of the GWT framework?) However, as long as I do it all "in-line" (e.g. createMockBuilder(LoginPlace.class).createMock()) I can create mock objects. Beyond that, to call the XxxActivity.start method, it requires passing a ClientFactory object - that contains references to various other objects (EventBus, PlaceController, defined views). (I assume I need to call "start" so the other methods can be called that use things initialized in start.) Does anyone know of some sample code that includes JUnit TestCase examples for a GWT-MVP app that uses the Activity, Place, ClientFactory model? I have spent a couple days battling this and have not made any progress. I am using Eclipse 3.6.1, GWT 2.1.0, JUnit 4, EasyMock 3.0 on a Windows XP system. -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

@def
Hi all,
I've been playing with @def and it's really nice. But it gets even
better because you can access the corresponding value in your Java
code.
my.css:
@def BORDER_WIDTH 1px;
MyCss.java:
interface MyCss extends CssResource {
int BORDER_WIDTH(); // Returns 1.
}
The only issue I have with this is that the naming conventions don't
play nice. In my.css I'd like to use BORDER_WIDTH (or better yet
BORDER-WIDTH) but in Java I'd like to use getBorderWidth.
For CSS class names we have the very useful @ClassName. Not
surprisingly, this does not work for @def. I'd like to do something
similar to
my.css:
@def BORDER-WIDTH 1px;
MyCss.java:
interface MyCss extends CssResource {
@DefName("BORDER-WIDTH")
int getBorderWidth(); // Returns 1.
}
Is there a way to achieve something like this?
Cheers,
Hilco

Re: Can't get to default place
This is what I'm doing.

oneMoreView.setPresenter(this);
panel.setWidget(oneMoreView);
}

Re: To smart GWT or not
Sorry that's quite absurd: SmartGWT is often introduced to solve performance problems, and it solves them. SmartGWT is intentionally designed to have a one-time-ever download of a feature rich runtime in exchange for reducing subsequent server requests. For example, Adaptive Filtering greatly reduces the costliest types of database hits: http://www.smartclient.com/smartgwt/showcase/#grid_adaptive_filter_featured_category .. and allows you to introduce an extremely powerful data highlighting system with no server load at all: http://blog.isomorphic.com/?p=234 If your application is the kind we target - complex enterprise applications which are used repeatedly and for significant lengths of time - this provides a gigantic performance boost, and once-ever download of cachable JavaScript files is a negligible factor. Look at a deployed SmartGWT application and you've got users humming along, ripping through the interface and nothing being downloaded anymore because it's all cached. And everyone is getting fast responses from the database because the Smart GWT framework is minimizing database load. The larger your application becomes, the more these benefits accrue. And, by the time you've built an application with comparable functionality with core GWT or another GWT-based framework, you're going to be downloading the same size runtime as SmartGWT anyway.

Re: CellTable not updating
I'm not adding a LayoutPanel to a PopupPanel. The only reason a popup
is involved is so I can prove my table is being updated - it's debug
code only.
My table is in a scroll panel, that's in a split layout panel, that's
in a dock layout panel.

Re: instanceof check on element always return true?
How come you always know exactly to point out the correct piece of doc snippet ;).. That keeps suprising me... like you memorized them... thanks... Anyway, what is the best way to discover the element type in this case? For example an InputElement?... I can't use the tag name in the InputElement as it's package protected :(.. One more thing: I bubble up the event from a checkbox, but how can I get this checkbox widget, that started the event, out of the received event?

Can't get to default place
Hello, everybody! I slightly modified hellomvp example, I just added one more place/ activity/view. It's called OneMorePlace, OneMoreActivity, OneMoreView. So right now I have scenario like this- HelloActivty starts OneMoreActivity, OneMoreActivity starts GoodByeActivity. But when I tried to step back from GoodByeActivity I get loop GoodByeActivity -> OneMoreActivity -> GoodByeActivity -> OneMoreActivity ... I never get back to default (HelloPlace) place. The same happens in my real application. What could be wrong? Any ideas? Thank you, Andrey -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: To smart GWT or not
I would use pure GWT, and heavy use of UiBinder, plus taking advantage of the latest 2.1 additions for mvp. Do you have problems with layout? What is your issue? Have a look to the DynaTableRf sample source code, it's a good example how to use nested layout panels for doing layouts.

That's the exact use case for FilteredActivityMapper and CachingActivityMapper (and how they're used AFAICT in "scaffold" applications generated by String Roo for the "master" activities). Of course you could do the exact same thing right into your ActivityMapper (the need here is to return the same Activity instance, so te ActivityManager will detect it and won't do the stop/start dance); you'd however loose a bit of "separation of concerns". -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

gwt-maven-plugin / "google plugin for eclipse" / working for anyone?!?!
We are trying to use gwt-maven-plugin to generate our mavenized gwt project. Our versions are: eclipse helios gwt 2.1 gwt-maven-plugin 2.1.1-SNAPSHOT We generate our initial project with the command line: mvn archetype:generate \ -DarchetypeRepository=https://nexus.codehaus.org/content/groups/ snapshots-group/ \ -DarchetypeGroupId=org.codehaus.mojo \ -DarchetypeArtifactId=gwt-maven-plugin \ -DarchetypeVersion=2.1.1-SNAPSHOT We then import the project into eclipse using "import / as existing project". Here are the problems we then encountered: (1) Eclipse compile errors complaining of unknown classes. These are classes the plugin generates and places in target/generated-sources/ gwt. The classes are Messages.java and GreetingServiceAsync.java. We work around this problem by adding target/generated-sources/gwt to our eclipse project classpath. (2) The class GwtTesttest.java has eclipse compile errors. We don't care much about this so for the moment we are just deleting that class. (3) This is the problem we can't find a workaround for. If we add dependencies to our pom, say spring framework, they then get added automatically to the "Libraries/Maven Dependencies". The problem comes when we invoke "Run As... / Web Application". Jetty fails to find classes in our newly added maven dependency, e.g Spring. Is there anyone out there that can shed some light on this?

It ended up I was stupid and didn't add my SVN install to my path. I thought the build had succeeded, but it failed part way through. Thanks for the tips though! The 'ant dist-dev' seems to run a lot faster than just 'ant', so that will save me a lot of time when I'm testing my changes. --Andrew On Dec 2, 11:28 am, Chris Conroy wrote: > To build gwt-user and gwt-dev, you'll want to run 'ant dist-dev'. > > If you're using GPE, you can simply configure your ant built jars as one of > your SDK choices from GPE's preferences, and then be sure to set your > project to use that SDK. > > The above should be the bare bones you need to get rolling.

Re: Observe (Hyper) Links in Texts to call JAVA methods
To intercept clicks on your anchor inside your html you can listen for
click events for the contentHtmlPanel and check if an anchor has been
clicked. Here is a short example using HTMLPanel:
public void onModuleLoad() {
HTMLPanel contentHtmlPanel = new HTMLPanel("Hello World");
contentHtmlPanel.addDomHandler(new ClickHandler() {
@Override
public void onClick(ClickEvent event) {
Element e =
DOM.eventGetTarget(Event.as(event.getNativeEvent()));
if(e instanceof AnchorElement) {
AnchorElement anchor = (AnchorElement)
e;
String href = anchor.getHref();
//absolute URI
String hrefAttribute =
anchor.getAttribute("href"); //href
attribute value
Window.alert("href:\n\n" + href +
"\n\nhrefAttribute:\n\n" +
hrefAttribute);
}
}
}, ClickEvent.getType());
RootPanel.get().add(contentHtmlPanel);
}
If your HTMLPane is a custom widget you can also do the following:
1.) Create a custom GwtEvent and its corresponding Handler, e.g.:
public class AnchorClickedEvent extends
GwtEvent {
.. getter method for your needed information ..
}
public interface AnchorClickedEventHandler extends EventHandler {
public void onAnchorClicked(AnchorClickedEvent event);
}
2.) Give your HTMLPane a new method (maybe through a
HasAnchorClickEventHandlers interface):
public HandlerRegistration
addAnchorClickedEventHandler(AnchorClickedEventHandler handler) {
return this.addHandler(handler, AnchorClickedEvent.TYPE);
}
3.) Add this.sinkEvents(Event.ONCLICK) to your HTMLPane's constructor
and then overwrite onBrowserEvent(Event event). In the onBrowserEvent
method you check for click events and do the same as in onClick() from
the code above.
The line "Window.alert(...)" will become this.fireEvent(new
AnchorClickedEvent())
That way you should be able to attach AnchorClickedEventHandlers to
your custom HTMLPane and your Event will have the information you
need. You could also use the EventBus if you like. Just skip step 2
and fire your event through the eventbus in step 3.

Re: CellTable not updating
LayoutPanels need an unbroken chain of parents that implement ProvidesResize
up to the RootLayoutPanel. If you add a LayoutPanel to a PopupPanel, it
will not layout correctly, and content will be hidden. You can get around
this by giving the outermost panel an explicit height and width.

Re: never ending topic "rich text editor"

Re: Safe Html check?
Apearantly I was reading too fast :(...
I seem to need the class SimpleHtmlSanitizer .
Thanks for the tip.
I am using it now, but noticed that snaitizeHtml always returns an
SafeHtml object.
public static SafeHtml sanitizeHtml(String html);
That's often not what I want, especially not when migrating to it's
usage. I rather have it return a string, but that method is private:
private static String simpleSanitize(String text) {
As it safes me the creation of this object that I don't use.
I use it at this moment through a central method in my UtilsGwt:
public static String toSafeString(final String text) {
return SimpleHtmlSanitizer.sanitizeHtml(text).asString();
}
Besides that, I see you throw an exception if the specified html is
null:
public static SafeHtml sanitizeHtml(String html) {
if (html == null) {
throw new NullPointerException("html is null");
}
return new SafeHtmlString(simpleSanitize(html));
}
I would prefer you just return null, especially as it's valid to set
null as: element.innerHtml(null)
Hmmm I also see that is escaped, so I probably better off
creating my own sanitizer ;)..
It would be nice if there would a default sanitizer that you can
configure maybe (flexible white list)..
Just one question: why are elements as div and span not whitelisted ?
I think because you could do something like:
or not?

Re: CellTable not updating
Yes, I added the table to the provider as a data display. I was not
invoking dataProvider.refresh() as I thought invoking
dataProvider.setList(myList) would update all displays. In fact, my
table is indeed updated. After I call setList on the provider, I can
query the table and see the updates have occurred (and popup the same
table in a Popup shows the updated table). The problem is, the table
was originally placed in a SplitLayoutPanel, inside a DockLayoutPanel,
etc., and that is not being updated.
I know the table is correct because I can query and put it in a popup.
I discovered that trying to figure out why the updated info was not
being displayed. If I wait until the table is updated and then place
it in the same panel hierarchy, it displays correctly. But updates are
not displayed.
Here's a small snippet with trace code where the update occurs (trace
information shows correct update):
public void setSelectedFoodGroup(FdGroupEntity foodGroup,
List foods) {
logger.entering(NutritionDataView.class,
"setSelectedFoodGroup");
logger.info("Adding food list of size: " + foods.size());
if (!dataProvider.getDataDisplays().contains(table)) {
logger.info("Adding display");
dataProvider.addDataDisplay(table);
}
dataProvider.setList(foods);
table.setPageSize(foods.size());
dataProvider.refresh();
logger.info(table.getRowElement(5).getInnerHTML());
logger.info("page start=" + table.getPageStart());
//PopupPanel popupPanel = new PopupPanel(true);
//popupPanel.setWidget(this);
//popupPanel.show();
}

Re: TabLayoutPanel does not listen to width
When you nest a LayoutPanel within something NON-LayoutPanel (like
Flowpanel); you need to explicitly set both - the height & width of
the LayoutPanel. Read "Using a LayoutPanel without RootLayoutPanel" of
http://code.google.com/webtoolkit/doc/latest/DevGuideUiPanels.html

Re: CellTable and multiple editable columns

Re: CellTable and multiple editable columns
You can store pending changes in a HashMap using the unique ID of the object as the key. When the use changes something in a row object, get it out of the map (creating it if necessary) and update the fields that changes. When the user presses Save, send all of the pending changes to the server.

Plugin Upgrade Woes
Hey guys, I'm having a really tough time today. I upgraded my GWT Plugin to 1.4v201010280047 at the update site and it has completely broken all of my projects. When I have the "Use GWT" item selected in my project properties, it will not generate any class files. the WEB-INF/classes folder structures (as well as the gwt.xml resources) are all there, but there are ZERO class files. When I uncheck the "Use GWT" box, all my class files are compiled as normal. Obviously, this has been pretty frustrating this morning. Is this a known issue with the new Plugin and Eclipse 3.5? I'm POSITIVE I'm installing the correct plugin for my version. Is there any way I can fall back to the previous version? There does not seem to be any listed at the update site.

Re: help with stack trace
Thanks Didier, I already did exactly that and it appears my problem is
with the gwt-canvas library I recently added. IE is saying my problem
is here:
function
gwt_canvas_client_CanvasImpl_$init__Lgwt_canvas_client_CanvasImpl_2Lgwt_canvas_client_Canvas_2V(this$static,
canvas){
this$static.gwt_canvas_client_CanvasImpl_element =
canvas.com_google_gwt_user_client_ui_UIObject_element;
this$static.gwt_canvas_client_CanvasImpl_context =
this$static.gwt_canvas_client_CanvasImpl_element.getContext($intern_1342);
}
On the second line of that function. The gwt-canvas author has made
demos that work with IE8 that I've tested but it doesn't seem to be
working for me. I doubt you'll know what is going on here, but in
case you do, or have any suggestion, I'd appreciate the help.
Thanks!

Re: GWT 2.1 Activities – nesting? YAGNI ? - an exa mple of where you NEED it !
For anybody considering GWTP (http://gwtplatform.com) as an alternative to GWT MVP, I want to stress out the fact that, despite the differences, there are a lot of similarity in the spirit of these two libraries. For example, gwtplatform's proxies are very similar to GWT's Activities. The place systems are quite similar too. One of the difference is that GWTP already offers mechanisms to reduce boilerplate via annotations and generators. You can hook (lazy) events to your presenters, define their place, etc. all with simple annotations right in your presenter. I'm sure GWT will evolve towards that at some point, but if you need it right away GWTP might not be a bad choice. Another difference is that GWTP fully embraces the concept of presenters, whereas in GWT MVP you need to create them using the provided building blocks. As you start nesting presenters it is useful to have mechanisms to maintain a hierarchy and propagate lifecycle notifications within that hierarchy. In GWT you will likely have to build some scaffolding for that. GWTP also has more bells and whistles such as hierarchical places (useful for breadcrumbs), support for tabbed presenters, etc. Where GWT shines is in the level of decoupling of the various components. And the GWTP developers appreciate this a lot. In fact, we plan to migrate the backend of GWTP towards the core GWT MVP classes (as they stabilize). Our goal is to let users of the current API benefit from any improvement provided by the GWT team. In time, we want GWTP apps to be interoperable with standard GWT MVP apps. A closing remark: GWTP offers other components that can be used independently of its MVP framework. If you want to use GWT MVP but need a good dispatch solution, take a look at GWTP dispatcher.

CellTable and multiple editable columns
I am using CellTable with simple pager to show ArrayList contacts. There are multiple columns that are editable mostly using EditTextCell. I have implemented FieldUpdater for editable columns. But I do not want to make server side save/update call each time there is change made to particular editable column. I would like to collect all the updates, lets say in ArrayList modifiedContacts and send it server side by using some kind of Save Contacts button. I am able to do this if I keep only one column editable, but moment I add multiple columns as editable, I start getting duplicate objects in my ArrayList modifiedContacts since each editable column is implementing FieldUpdater. When 2 or more columns of same row are updated, FieldUpdater of each column is fired, storing duplicate objects in ArrayList modifiedContacts. I could use Set instead of ArrayList to store unique contact objects but is there better way to do this ?

Re: Customizing CSS Default GWT Widgets with CSSResource
Right know I'm customizing default gwt widgets.
As a starting point I took the standard theme, I copied the
standard.css file from standard theme and then declared this in my
ThemeBundle like this :
@Source("standard.css")
CssResource getLegacyCssResource();
Then I have added @external declaration to every class listed in this
file. Thanks to this I don't have to subclass CssResource and there is
no need to declare getters for classes found in this css file.
Below are external declarations for all the class names found in
standard.css :

After that you can very easy customize gwt widgets, you can use @def

help with stack trace
I've been using GWT for years (since around release 1.4) but I'm having a problem with a stack trace I can't figure out. I develop on a mac and primarily test with Safari and Firefox. My application has worked in IE(8) in the past but in my most recent test it is failing and I can't figure out why. Typically in the past when IE has failed I'll open in dev mode (previously hosted mode) and then get the stack trace but in this case the stack trace isn't pointing to any of my code. The problem happens immediately when I open up my application in IE8. Here's the complete stack trace: 00:02:02.218 [ERROR] Uncaught exception escaped com.google.gwt.core.client.JavaScriptException: (TypeError): Object doesn't support this property or method number: -2146827850 description: Object doesn't support this property or method at com.google.gwt.dev.shell.BrowserChannelServer.invokeJavascript(BrowserChannelServer.java: 237) at com.google.gwt.dev.shell.ModuleSpaceOOPHM.doInvoke(ModuleSpaceOOPHM.java: 126) at com.google.gwt.dev.shell.ModuleSpace.invokeNative(ModuleSpace.java: 561) at com.google.gwt.dev.shell.ModuleSpace.invokeNativeObject(ModuleSpace.java: 269) at com.google.gwt.dev.shell.JavaScriptHost.invokeNativeObject(JavaScriptHost.java: 91) at com.google.gwt.core.client.impl.Impl.apply(Impl.java)at com.google.gwt.core.client.impl.Impl.entry0(Impl.java:214) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java: 39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java: 25) at java.lang.reflect.Method.invoke(Method.java:597) at com.google.gwt.dev.shell.MethodAdaptor.invoke(MethodAdaptor.java: 103) at com.google.gwt.dev.shell.MethodDispatch.invoke(MethodDispatch.java: 71) at com.google.gwt.dev.shell.OophmSessionHandler.invoke(OophmSessionHandler.java: 157) at com.google.gwt.dev.shell.BrowserChannelServer.reactToMessages(BrowserChannelServer.java: 281) at com.google.gwt.dev.shell.BrowserChannelServer.processConnection(BrowserChannelServer.java: 531) at com.google.gwt.dev.shell.BrowserChannelServer.run(BrowserChannelServer.java: 352) at java.lang.Thread.run(Thread.java:662) Is there anything I'm missing?

Re: Building GWT from source
To build gwt-user and gwt-dev, you'll want to run 'ant dist-dev'. If you're using GPE, you can simply configure your ant built jars as one of your SDK choices from GPE's preferences, and then be sure to set your project to use that SDK. The above should be the bare bones you need to get rolling. You may also want to check out the eclipse README file for building from source and using Eclipse: Checkout the Eclipse README file for instructions on getting eclipse setup: http://www.google.com/codesearch/p?hl=en#A1edwVHBClQ/eclipse/README.txt&q=README%20package:http://google-web-toolkit%5C.googlecode%5C.com&sa=N&cd=2&ct=rc On Wed, Dec 1, 2010 at 5:15 PM, aarnott wrote: > I'm investigating a bug I reported (here > http://code.google.com/p/google-web-toolkit/issues/detail?id=5669). > I'm hoping that I can figure out a fix myself and either post the > solution in the bug report or actually figure out how to submit it. > > * I'm not very experienced with SVN (although I am familiar with > Perforce) > * I've never used ant before > * I'm not experienced building jars > * I'm fairly experienced with Java (otherwise I wouldn't even try > tackling this one) > > I've followed the instructions for downloading the source and running > ant in the source directory.

onResize issue with IE 7
Hi, I found a problem with onResize on IE 7: My panel receives an onResize, but at this point, getOffset[Width| Height] returns the old window size, not the new size. I am currently using a workaround like this: Within onResize I schedule a deferred command, which does the resize actions later, when the new window size is returned by getOffset[Width| Height]. This workaround is not nice, since I cannot hide it in some base class, but have to deal with in every derived class. In every onResize method I cannot rely on getOffset[Width|Height], so I always have to do the deferred stuff within the derived classes. Is this a known issue and can I expect a solution in the near future? Or is there a better workaround? Thank you very much!

SuggestBox not displayed on Tomcat Server
Hello,
I have encountered a problem using a SuggestBox when the application
is deployed on a Tomcat server.
My interface, which contains several SuggestBox widgets, displays the
widgets correctly when I deploy using the Eclipse built-in server and
when I deploy to the app engine server. But when I deploy to a Tomcat
server, the SuggestBox widgets do not display the suggestions.
My target tomcat server is 5.5.27 but I have tried on 5.5.29 with the
same result. I have a very small CSS entry for the SuggestBox to allow
a scrollable suggestion list:
.gwt-SuggestBoxPopup {
overflow-y: auto !important;
max-height: 250px;
}
Does anyone know why this might be happening just on a tomcat server
(all the other widgets appear to be working other than the
SuggestBox)? I can provide more details if required.
Many thanks,

CellTable not updating
I have CellTable being fed data from a ListDataProvider. I set a list into the data provider and can then query the CellTable and see the updated HTML results. Popping up a window with the table also shows an updated table. The problem is, I originally put the table into a DeckPanel that's nested in several other panels - dock, split,... and it shows in its original "no data, only column header" form. When the data provider is updated, the CellTable is not repainted. I can query it and pop it up in another window, so I know the table is updated - it's just not reflected in the panel in which it was originally placed. Am I missing something simple here? Even trying to force a layout at the root panel doesn't cause anything to show up. Any suggestions on the problem or how I might debug this?

GWT client overlay generation from XSD
Hello, I was wondering whether or not there was any facility to generate JavaScript Overlay objects from XSDs or GSON objects? We have an application that is talking to a JSON REST backend. We have defined all our communications via XSD and use GSON to generate Java objects that serialize/deserialize to/from JSON. I would really like to be able to just generate my JavaScript overlay objects from this same source. Are there any facilities that can do that for me?

Observe (Hyper) Links in Texts to call JAVA methods
Hello everyone,
I've been searching quit a lot for a solution to this problem but all
I found wasn't 100% satisfactorily:
I use RPCs in my GWT project to get some texts like
String text = " ...bla bla open me
blablalb ";
Those strings will be loaded into the content of a HTMLPane like this:
contentHTMLPane = new HTMLPane();
contentHTMLPane.setContents(text);
And the user can see the new content after the RPC. What I need is the
following:
When the user clicks on open me it should call
the method:
public void openConent(String id){
...
}
...of course with the ID of the Link. The openContent method is
present in the class which processes the text and so on.
So I have to observe the "user clicks on a hyperlink" event somehow.
Somehow like:
(pseudocode)
if(eventHyperlinkOccurs) {
this.openConent(event.getURLofLink);
}
All I've found is this:
http://googlewebtoolkit.blogspot.com/2008/07/getting-to-really-know-gwt-part-1-jsni.html
which tells me that it's possible to call JAVA methods with JS
methods. This solution is OK but I've been wondering if there is a
"smaller" solution with events/observers?
Thanks in advance!

Dynamic inclusion of UI/script
Hi All, We will be creating a huge ERP system, with lots of screens. I am looking if there is a way to dynamically include screens, I mean if a user sends a request, the system will look for a xml file, may be a ui binder file, compile the script and sends the generated script back to the user and from then the already generated script will be sent. I guess this will minimize the size of the generated javascript files and the loading time. I think the Histroy can be maintained in the same way and I guess there wont be any need for modules then. Let me know your thought on this or pros/cons or any way to achieve this ? Thanks, Abdullah -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

LayoutPanels want to be nested inside LayoutPanels. What if instead of
using a FlowPanel you used a LayoutPanel for the main uibinder widget.
The way I've ended up debugging some of these weird issues with
LayoutPanels is by cracking open Firebug and hacking away at styles
until things start to look right.

Re: GWT 2.1 DateTimeFormat & locale changes?
I think I have solved my date/time issues by forcing a locale, but I would welcome suggestions for a better solution. In my module XML, I added the following line to include some internationalization code: I added the following line to my module XML for my locale: Including the locale extend-property increases the GWT compile time, since the compile does each browser/locale combination. This was the most undesireable piece of my solution since it basically doubled my GWT compile times. I tried to set the default locale using another bit of XML found at http://code.google.com/intl/es-AR/webtoolkit/doc/latest/DevGuideI18nLocale.html#LocaleDefault, but I could not even get the GWT compile to work when including that XML. The last required piece was adding the following line in my HTML file: This gives it a default locale, but I believe that it can be overridden with request parameters. I did test this on a couple projects, and it worked for both. However, I did not test with different locales. It seems that a new GWT 2.1 project has the same issues, so this is not just a GWT 2.0 conversion problem -- I tested by adding a DateBox to a new GWT default project.

Showing and hiding a ButtonCell in a CellTable
In a CellTable I'm using a ButtonCell column. The button for each row
should show only when a condition is true. How do I achieve that?
This is my code now:
Column myColumn = new Column(new
ButtonCell()) {
@Override
public String getValue(Person object) {
return "Button label";
}
};
myColumn.setFieldUpdater(new FieldUpdater() {
@Override
public void update(int index, final Person object, String
value) {
object.performOperationOnObject();
// and do some other stuff...
}
});
myCellTable.addColumn("", myColumn);
The button should only show up if the Person.showButton() == true.

We are currently looking into smartgwt, because it seems that over
