delayTestFinish() from GWTTestCase not working in pure java tests
I'm trying to verify that some JavaScript code behaves identically to an existing Java library. I've created some tests that subclass GWTTestCase to check this. Unfortunately, when I try and do the pure-java test in development mode (by returning null for the module name, as the documentation suggests), the methods like delayTestFinish() don't appear to work. Tests just finish as soon as the test method exits. Is this the intended behavior? If so, has anybody made a pure-java implementation of GWTTestCase so test logic can be shared between client and server code? -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Web workers
Okay, I've looked at my code.
I modified the DedicatedWorkerTemplate.js file from speedtracer to include
the following lines near the top (first two should already be there):
$self = self;
$sessionId = null;
$wnd = self;
$doc = self;
window = self;
This kept a lot of the code I was using that was looking for a $wnd and
$doc variable happy. Of course, it doesn't *actually* provide window or
document objects, it just renames them so the code doesn't blow up. This
has been part of the problem with the project I've been working on, I'm
using an external library that is unaware it is being used as a worker and
while in theory it's just doing processing, it's still expecting to find
certain values in window and document objects, so I've been slowly and
annoyingly figuring out how to create a mock window and document object to
accommodate the code. But it's a pain and I'm considering just rewriting
it. Unfortunately that removes the usefulness of the library since I was
using it to save me from coding my own implementation (and I'd have to keep
porting over the updates as they occur, bleh). On the other hand, running
the third-party processing in the main thread really kills the app's
performance (especially on mobile).
Sigh. Apparently I needed to vent... Sorry about that.

I've played around with web workers on GWT, but it's not a lot of fun.
You can't use normal GWT devmode on them (though maybe superdevmode would
work?). So you essentially have to write the worker, compile it, and then
call it from your non-worker code and hope it does what you want.

Re: Best serverside architecture(framework/stack) to use with GWT for large application...please show me the light
Hi Seth, I personally am not a fan of Spring. I'm generally not a fan of anything that says, First, create a bunch of XML files (GWT excepted :) ). That's why I gravitated to Guice for all my DI needs. That said, Guice and Spring aren't quite the same thing, and you could leverage both of them. However, it is probably unnecessary to do both Guice and Spring in a GWT app. You can do anything with one DI framework that you can do with the other, and if you are leaning to Spring, you make a fine choice and you can ignore the rest of my post. At my workplace, the way we do GWT projects is we create a WebXml.java in the server package that implements GuiceServletContextListener and point the web.xml to that class. The WebXml contains servlet mapping modules, db connection modules, and other Guice modules as needed. On the client side, we generally use MVP structure with GIN. The MVP structure is a lifesaver for large projects in my mind. Our more recent projects have used the Activity and Places framework described on GWT's website with the main exception that the ClientFactory object is unnecessary since GIN provides the various resources instead of ClientFactory. At my work we've got two projects that clock in around 34k and 46k lines of Java (not including XML or other artifacts) as well as smaller projects and they use the methodology I described.

The goal is to only have a single permutation? I thought the multiple permutation system of GWT was only good (though admittedly I have been burned by IE9 and 10). Isn't it preferable to not send -moz-linear-gradient(...) to Chrome and -webkit-linear-gradient(...) to Firefox? (Same with mozIndexedDB vs webkitIndexedDB.) I thought this made the code smaller and better tailored than the this or this or this style of coding. Also, assuming I go this route, how do I tell GWT to just do one permutation without UA concerns? I've been working on an app that I was originally only targeting webkit for (thus set-property name=user.agent value=safari/), but nothing in it should necessarily have broken in Firefox (besides the WebSQL stuff). So I decided to point Firefox to it, and immediately got an alert saying Firefox wasn't supported, despite the app working well enough. Obviously it was easy to fix by adding gecko1_8 to set-property, but how do I create the one permutation to rule them all that doesn't complain? Again I'm not questioning Elemental utility greatness, but so far it looks to be much more important to GWT internally than to the rest of us, mere GWT consumers. Everyone has different needs. I'm very happy to be able to use Elementals to use a new Web API without having to hand-generate the overlays myself.

GWT Web Workers - multiple modules on same page
I am trying to use GWT Web Workers (code based on the speedtracer Web Worker implementation), but I am not able to make the worker module participate in dev mode, requiring me to recompile the worker every time I change code in it. Has anyone else worked on this code and dealt with this problem? When I create a separate module for my web worker and try to run my code, I get the error alert is not defined because the permutation is not created and the worker is trying to run alert(Module 'myworker' may need to be (re)compiled), which fails since workers don't have access to window.alert. If I compile the worker module, I get a permutation created which is served up correctly when my main module tries to load the worker at ../myworker/myworker.nocache.js. No errors, everything seems to work correctly, but the myworker module is not participating in dev mode despite my main module participating. So I can modify the code that calls the workers in dev mode, but any changes to the workers requires a recompile of the worker module. Is there a way to make the worker work with the code server? The Worker linker is based on a SelectionScriptLinker, but I'm not sure if it's the linker that's refusing to generate a dev mode permutation, or the code server, or dev mode, or what. Has anyone dealt with this problem? Does anyone have any ideas? Thanks, Derek -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Generate URL to image stored on server
Because you need to use GWT.getHostPageBaseURL() not GWT.getModuleBaseURL() (or use modulebase, but prepend ../ to your filename). I assume the actual url to get the image is http://127.0.0.1:/card_designer/exampleImage.jpg . That should get the image. BUT, going back to the working directory thing, it IS problematic to write files there. At least, it is if you expect those files to be there long term. Every time you redeploy a war in production, your app server (tomcat, glassfish, whatever) will overwrite everything in the directory which will erase working directories like card_designer. If you just need some temporary space to store an image while the user does things like cropping the image and then they download the finished product, then that might be fine. But if they expect that url to work long term, I wouldn't use that space. (Also, don't know if you've considered the problem of lots of people uploading images named the same thing or not.) I recently had to do something similar to what you did. We have a directory mounted on our production servers that holds uploaded images (and isn't accessible via the web). When someone uploads a file, I check the MD5 hash of the file to see if it's a match of another image (in my use case, it's very probable that a user will upload the same image or images every time they use the app). If it's not, then I write the file to the shared directory in the MD5hash.ext format. Either way, I then return the calculated filename to the GWT code. The GWT code then immediately executes a request to a servlet hosted at /mymodule/images/* and uses the path info to get the filename and goes to look it up in the shared directory and relays the data through the servlet.

Re: convert dom element to widget
If your dom elements are all of a particular type that has a GWT analog, you can possibly wrap them using a convenience wrap() method.

Re: Error with the web application starter project
greet isn't a file, it's a servlet endpoint. Your GreetingServiceImpl class is mapped to that endpoint in your web.xml file (under the war/ WEB-INF folder). So I'd check your web.xml file and your GreetingServiceImpl class. Make sure the classnames match, make sure the compiled class (under WEB-INF/classes) is there, check the deploy logs.

AsyncProvider does not need to be bound to an implementation.
AsyncProvider should be managed by Gin.

Re: loading an image
I'd be surprised if that's related to GWT, but maybe I'm wrong. Are you sure you're using the right URL? If you're using a relative path, you might get tripped up between hosted and compiled mode. If you're using the url /myimage.png, then hosted mode will probably work and real mode would probably fail (assuming you set up your servlet as /myimage.png), since real mode would probably actually be at /myproject/myimage.png or something like that. I would grab some developer tools and inspect your image source and make sure that the url it's going to actually works. Also look for any other errors that might be on the console.

Re: loading an image
The loadhandler won't fire until the image is added to the DOM. So for
example, you could put view.setImage(image) outside the loadhandler,
and GWT.log(loaded!) inside the loadhandler, and then you should see
loaded! in your dev console.
But a loadhandler is not required for loading an image, it's only if
you want to respond to the image being loaded. For example, I'm
working on a GWT app that shows a progress bar until an image gets
loaded, and for that code, I put in a loadhandler on the image that
removes the progress bar in the onLoad() (and I also have an
errorhandler that displays a message and remove the progress bar if
the image fails to get loaded). But if you just want to load an image,
you only need to set the source and add it to the page and it will
load.
I don't actually see anything wrong with your first attempt. Why did
it fail outside of hosted mode?
If you want to load your image ahead of time so it displays
immediately, try Image.prefetch(url).

Re: Start GWT App from JavaScript
I don't think you need to write a linker. Just create a script element
in your js code and add it to the DOM when you need it.
For example,
button onclick=dogwt()Do GWT/button
function dogwt() {
var s = document.createElement(script);
s.src = my.nocache.js
document.body.appendChild(s)
}
This way is the same way jsonp works, so Google jsonp if my code is
broken or you need more options. (Forgive me for not testing that
code, posting from a tablet.)
document.write() clears the entire document before writing, which is
why your screen goes white.

Drag and Drop to a RichTextArea / IFrame?
I'm trying out some of the fun drag-and-drop stuff in GWT. My current
attempt is to drag a file into a richtextarea, but nothing seems to be
working correctly. It works fine if I use a FlowPanel or some other
GWT widget, but not a RichTextArea despite it have an addDropHandler
method.
Anyone have any experience with this?
My code in onModuleLoad:
DropHandler drop = new DropHandler() {
@Override
public void onDrop(DropEvent event) {
event.preventDefault();
String data = event.getData(text);
GWT.log(text is +data+ and there are
+numFiles(event.getDataTransfer())+ files);
}
};
RichTextArea rt = new RichTextArea();
rt.addDropHandler(drop); // never called even after drag-and-dropping
a file on the rt
RootPanel.get().add(rt);

Re: Radiobutton vs checkbox in celltable
The simplest thing to do is to copy and paste CheckboxCell as RadioCell (for example) and then just change the templates at the top to input type=radio name=blah But you do need to put in a name for a radio cell, and if you use blah as the name than the radio cell will give you problem if you have cells in multiple columns.

Re: Strange Request: How do I open a new browser window, run part of the GWT application there, and communicate with it
I once had to do something vaguely similar. I needed to open a GWT app in a window from a non-GWT app. I called var win = window.open(GwtHtmlPage.html) and then set the data the GWT app needed with win.blah = 3 or whatever. Then my GWT app used some JSNI to fetch that value. The problem as Robert metioned is that GWT doesn't really want you doing inter-window communication. So you have to sling your own JSNI.

Re: File download by GWT client
Yes, FileSystem and FileWriter are HTML5 Javascript APIs that are
available to browsers that support them.
And yes, with JSNI. Overlays are described here:
http://code.google.com/webtoolkit/doc/latest/DevGuideCodingBasicsOverlay.html
For example, the FileSystem object described at
http://dev.w3.org/2009/dap/file-system/pub/FileSystem/#the-filesystem-interface
would have an overlay like:
public final class FileSystem extends JavaScriptObject {
protected FileSystem() {
}
public native String getName()/*-{
return this.name;
}-*/;
public native DirectoryEntry getRoot()/*-{
return this.root;
}-*/;

Re: Detect *only* when browser is closing (WindowCloseListener)
I'm curious why you have such a specific requirement. When would you only want a window closing event to fire on browser close? Anyway, I don't think you can do that. Each window or tab shouldn't know about any window or tab it didn't create. It might be possible to detect browser close through an extension/add-on, but I haven't ever looked into it. Actually, it might be possible to do that on modern browsers using sessionStorage. You may be able to add an event to be notified when the session is being destroyed (which *should* be on browser close...), but I haven't ever tried that. Would your requirements allow you to do something on user return? If so, you could (again) use session storage or a cookie to let you know if you've seen the user before. If you haven't this time, then you can do whatever cleanup necessary (or whatever you're trying to do).

Re: Extending/embedding DialogBox
I generally create custom Dialogs as their own uibinders and then
instantiate them from elsewhere. So I might use the code below, and
display it with new MyDialog().center();
Is this best practice? I'm not sure. I think there are some who hold
to the idea that you should let your dialog's content be its own
UiBinder, but that is not precluded by the strategy below. It's the
way we do things at my organization.

}

I am a little confused over the best practice use of DialogBox when

In UIBinder xml, you can include a DialogBox element, and configure it
using, say, the caption element or text attributes. This seems to hint
that you can embed a full DialogBox definition, letting a widget carry
its own DialogBox to pop on demand.
However, doing so results in the dialog box being shown as part of the
page on load, and some comments seem to indicate that you're not
supposed to do this.
If, on the other hand, you extend DialogBox as its own stand-alone
widget, you only get to define the *contents* of the dialog box in the
ui.xml, forcing you to set things like caption and glass pane in the
Java code, which seems to defy the purpose of a uibinder in the first
place.
What am I missing?

Re: Is it ever possible for an asynchronous service method's callback to get called without yielding to the browser's event loop?
The only time I encounter what you describe is when I mock the server
side code on the client side. In other words, in your code example, I
might have myRemoteService actually be an instance of some
MyRemoteServiceAsyncMock, that returns dummy data while I wait for
someone else to write the server side impl (or until I do it myself).
In that case the async call is actually sync and so I might need a
deferred command to make sure that code outside the async call is run
before the call itself. Otherwise you should be able to count on
things happening in the expected order.
On Jun 17, 12:29 pm, Tad tadwo...@gmail.com wrote:
Is the AsyncCallback framework implemented in such a way that when a
RemoteService method is called, is it a GUARANTEE that the browser's
event loop will execute at least one cycle before its callback (i.e.
onSuccess or onFailure) gets called?
For example:
...some code...
myRemoteService.myMethod( myParameter, new AsyncCallbackString()
{
public void onSuccess(String result)
{
}});
...some long running code...
In the above example, if the result of myMethod happens to return
before the some long running code finishes, will the browser's event
loop always receive at least one cycle before onSuccess() is called?
Or is it ever possible that onSuccess() could get called without
yielding to the browser's event loop?
Another way to ask this question would be: Is there ever a scenario
where it is necessary to do the following (or put the scheduleDeferred
call inside myMethod's onSuccess callback)?
Schedule.get().scheduleDeferred( new ScheduledCommand()
{
myRemoteService.myMethod( myParameter, new AsyncCallbackString()
{

Re: Hierachy of autobean for state serialization
Thanks for posting this, Panam. I was just starting to consider using
AutoBean with LocalStorage, since storing a JSON string seems like the
best solution than rolling my own custom serializer. I haven't gotten
too far into it beyond some simple test cases.
For 2), I seem to recall seeing that polymorphism for AutoBean is an
eventual goal for the GWT group, but 2.3 doesn't support it.
For 1), my thoughts would either be on using AutoBeanVisitor (which
can only see things already explicitly added, so probably not) or a
generator (which might trip up AutoBean's generator), but I haven't
tried either in the way you describe, so maybe I'm wrong.
I think the official way is to have an interface for each subclass in
your AutoBeanFactory, so for example:
public interface Base {
getName() / setName()
}
public class BaseImpl implements Base { ... }
public interface Color extends Base {
getColor() / setColor()
}
public class ColorImpl extends BaseImpl implements Color { ... }
public interface Serializer extends AutoBeanFactory {
AutoBeanBase wrap(Base wrap);
AutoBeanColor wrap(Color wrap);
}
That works if you only have a small handful of subclasses, but it gets
progressively worse the more you add.

Re: User GWT to develop android apps that are not browser based?
Not sure what you want here. Android development is a separate thing from Web development, and GWT is for the web. However since they're both Java-based there are opportunities to re-use code in either, if you want to write both an android and web version of your app. Granted, Android has WebViews which embeds the webkit rendering engine in your app, and you can easily use GWT for that aspect of development (I've done that). The result would certainly be something you could put on Android Market, though hopefully you're adding some Android integration and not just repackaging a webpage. Since you've already been watching Google I/O talks, let me recommend a couple more: http://www.google.com/events/io/2011/sessions/html5-versus-android-apps-or-web-for-mobile-development.html - HTML5 vs Android Apps goes into a lot of the reasons you might want to create an Android App rather than a mobile web app, and vice versa. To boil down a lot of it, mobile web apps are cross platform (work on iOS, webOS, etc), while android apps allow tighter integration with the device. http://www.google.com/events/io/2011/sessions/android-app-engine-a-developer-s-dream-combination.html - This is a really cool talk that I wish I had attended. It shows how, using GPE, you can create an app that does reuse a lot of code between GWT and Android with an AppEngine backend.

Setting extra information on provided Cells?
Far too often, I seem to have to create new Cells that do very similar functionality to built-in Cells. For example, I've had to create a SelectionCell that can alternately show a listbox as either enabled or disabled, or create a SelectionCell that has different options in the listbox depending on the row type. I've had to create an ImageCell that shows alt text, an EditTextCell that uses a textarea instead of an text box, and a CheckboxCell that displays a radio button instead of a checkbox. In each of these cases, I have to go find the GWT source code for the cell, copy and paste it into a new class in my project, and start making the tweaks necessary to do the desired result. Already this has required tweaks to my code since CheckboxCell has changed since 2.1.0 and so RadioCell has needed corresponding changes. This seems to break the OO design philosophy, but there aren't easy extension points in the above cells that make subclassing easy. Is there a better way to create these Cells without the ugly?

Re: How to restore previous value of EditTextCell in Cell Table
I only know a bad way to do this, so I'd like someone else to show me
a better way to do this.
As with most GWT Cells, as soon as I want to do something different, I
have to create my own. So I suggest you look up the code for
EditTextCell, copy and paste it into a new MyEditTextCell and then
change the commit() method to do what you want.
In my case, I needed EditTextCell to use a textarea instead of a
textbox, so I had already copied and pasted the code out to make it
use a textarea. When the requirement came down that I needed to give
people a confirm when they changed the text (sigh), I modified the
commit method similar to:
private void commit(final Context context, final Element parent,
final ViewData viewData, final ValueUpdaterString valueUpdater) {
if(Window.confirm(Really update value?)) {
String value = updateViewData(parent, viewData, false);
clearInput(getInputElement(parent));
setValue(context, parent, viewData.getOriginal());
if (valueUpdater != null) {
valueUpdater.update(value);
}
}
}
I'd be happy if someone could point out a way to do things like this
in a way that allows me to not have to copy/paste GWT Cell code into
my own project.

Re: Events: One handler many sources
Hi Mike, My first thought is that maybe using events isn't really what you want. Without knowing specifics, is this something that would fit better as a singleton? Foo.get().doFoo(); (or if you use GIN bind(Foo.class).in(Singleton.class); and then you can @Inject Foo) However, if the event model is what you want to use, you can pass around a common EventBus with which you can fire() events. in module load or wherever appropriate: myEventBus.addHandler(FooEvent.TYPE, new FooHandler()); and in your sources myEventBus.fire(new FooEvent()); Hope that helps, Derek On Mar 5, 3:38 pm, manstis michael.ans...@gmail.com wrote: Hi, Perhaps I horribly misunderstand GWT'seventmechanism, but I am struggling with wiring up the following scenario with the usualHandler,Eventtypes... * I have oneHandlerof a specificeventtype * I have multiple sources of the sameeventtype I didn't want to add HasXXXHandler to every source just so I can callEvent.fire(this) to trigger theevent.

Re: SelectionCell
I had to roll my own SelectionCell when I needed to do that. The version I wrote ended up using app specific classes so it's not really fit for mass consumption. In general though, start with the SelectionCell code, remove indexForOption and options, and add a MapK, ListE options in its place (making K whatever type you need it to be (enum in my case)). Then fix all the build errors in the rest of the code. :) In the render and onBrowserEvent methods, you'll probably need to call context.getKey() to get the row key. If you *don't* use a keyprovider on your celltable, then the key will be the row object (which is what I do). Cast the object to what you know it will be and then call the methods on that object you need to get the key for your options map. Now you have your list of options per row object. Not the prettiest code, but it got the job done.

Re: GPE auto-complete only partially working for UiBinder tags
Sekhar, Can you explain that more clearly? I don't see any Make this the default editor option. Eclipse will remember which editor I want to use for a particular file, but I don't see a way to make that change globally. For example, if I open Widget1.ui.xml, it opens in WindowBuilder. I can right-click and choose Open With - UiBinder Template Editor (or Other - UiBinder Template Editor, they work the same for me) and then whenever I reopen Widget1.ui.xml, it reopens in UiBinder Template Editor. However, when I then open Widget2.ui.xml, it opens in WindowBuilder, and I have to repeat the process for that and every other *.ui.xml file I have. I would like to make the change once, and then any time I open a *.ui.xml, it automatically opens in the UiBinder Template Editor.

Re: GPE auto-complete only partially working for UiBinder tags
I can't make it default and filed a bug. http://code.google.com/p/google-web-toolkit/issues/detail?id=6039 You should be able to go to Window Preferences General Editors File Associations and in the list on the right, choose *.ui.xml and choose between UiBinder Template Editor and WindowBuilder Editor, but it's not there. I tried clicking Add... and adding *.ui.xml as a new type, but it throws an assertion error in the Eclipse log. On Feb 20, 4:21 pm, Filipe Sousa nat...@gmail.com wrote: Thanks for the tip Thomas.

Re: development mode rpc call is an http OPTIONS instead of POST
I'm having a very similar problem, but don't have an answer yet. I'm using the RequestBuilder to do an HTTP POST to our IIS server.

Re: development mode rpc call is an http OPTIONS instead of POST
I found out what was causing my problem. My RequestBuilder was originally constructed as: new RequestBuilder (RequestBuilder.POST, http://localhost/appdir/somefile.aspx;); Once I used either a specific machine name or relative path then it no longer switched the from POST to OPTIONS. I now have the following: new RequestBuilder(RequestBuilder.POST, /appdir/somefile.aspx); On Jan 5, 7:49 am, Derek dealy...@hotmail.com wrote: I'm having a very similar problem, but don't have an answer yet.

RequestBuilder.sendRequest() failing in firefox but not IE
Hi
I recently upgraded to GWT 2.0 along with GXT 2.1. My application was
working properly back at GWT 1.7, and now it mostly works fine with
2.0. But there is a problem with web requests and responses I can't
figure out.
When run in hosted mode and debugging in Java with Eclipse everything
is fine. My GWT app communicates with the server from Firefox with no
problems. However once I compile the app into javascript and run it
from within Firefox or Chrome, none of my requests appear to be making
it to the server (which is IIS). However if I use IE 7 the javascript
compiled code works just fine.
When I'm debugging with Firebug I don't see any of my httprequests
going out to the server, and all responses come back with an empty
string from Response.getText().
My code which sends the HTTP POST looks like this:
RequestBuilder builder = new RequestBuilder(
RequestBuilder.POST, INVOKE_URL);
builder.setHeader(Content-Type,
application/x-www-form-
urlencoded; charset=UTF-8);
WebResponseRequest invoke = new
WebResponseRequest(callback);
request = builder.sendRequest(
buildRequestData(method, parameters),
invoke);
public void callback(Request req, Response resp) {
String str = resp.getText();
if (str.isEmpty())
throw new Exception(no response data);
...
}
Any ideas of what maybe wrong here?

1.7-2.0 hosted mode no longer working
Hi I had my GWT app running in hosted mode last week with GWT 1.7, Eclipse 3.5, GXT with the server side hosted by IIS. So I upgraded to GWT 2.0, upgraded the plugin in Eclipse, downloaded the GWT 2.0 SDK and am trying to get my application running once again. So far no luck though. My old run configurations are still in Eclipse, it was originally setup so that I was not running the built in server (since we have IIS on the backend) and we had this for program arguments: -whitelist http://localhost/war/KryptoniteDesktop.html;. If I launch my old run configuration I get the new Development Mode window which shows the following URL to view in development mode: http://localhost:/KryptoniteDesktop.html?gwt.codesvr=172.17.3.67:9997 However this doesn't work, when I point my browser to the suggested URL I get the following: Firefox can't establish a connection to the server at localhost:. I don't know why its referencing localhost: given I don't have the checkbox for the built in server checked. I can't find anything that discusses using the new Development mode when not using the built in server. Do I need to use the bult in server when in Development Mode of GWT 2.0? Any idea how to configure this so I can debug my application again? Thanks, Derek -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

TextBox.setFocus() not working as expected in Firefox
package sample.test.client;
import com.google.gwt.core.client.EntryPoint;
import com.google.gwt.user.client.ui.FocusListenerAdapter;
import com.google.gwt.user.client.ui.RootPanel;
import com.google.gwt.user.client.ui.TextBox;
import com.google.gwt.user.client.ui.VerticalPanel;
import com.google.gwt.user.client.ui.Widget;
/**
* Entry point classes define codeonModuleLoad()/code.
*/
public class TestClient implements EntryPoint {
/**
* This is the entry point method.
*/
public void onModuleLoad() {
VerticalPanel vPanel = new VerticalPanel();
TextBox tBox1 = new TextBox();
TextBox tBox2 = new TextBox();
tBox2.addFocusListener(new FocusListenerAdapter() {
@Override
public void onLostFocus(Widget sender) {
TextBox tBox = (TextBox)sender;
if(!tBox.getText().equals(good))
tBox.setFocus(true);
}
});
vPanel.add(tBox1);
vPanel.add(tBox2);
RootPanel.get().add(vPanel);
return;
}
}
In hosted mode (WinXP GWT 1.5.1) and in IE (IE6 and IE7) this code
works as expected - if the user types in something other than good
in the second box and attempts to leave the box then focus is
immediately returned to tBox2. However, in Firefox (FF2 and FF3)
focus is not returned to tBox2 when it should be.
