Re: JAXB in model classes also used by GWT RPC
Hi, I had the same problem a while ago and asked exactly the same question. Why don't jaxb annotations work? I remember reading somewhere that if things won't break if gwt cannot find annotation source files, but I'm not sure if I really read this or not. Well, I didn't get an answer to that question, but I did get a suggestion for how to make things work for me. I took the jaxb source code and put the annotation files to my project so gwt can compile them.

GWT Bindings for Google Map Utilities
If you use the gwt-maps library to add map capabilities to your GWT apps then you might also be interested in the gwt-maps-utility library, it extends the gwt-maps library with some useful map utilities: http://code.google.com/p/gwt-maps-utility/ Samples are available as well: http://gwt-maps-utility.appspot.com/samples/v1.0/HelloMapsUtility.html Bobby -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

NumberFormat not understanding its own output?
I can't get the NumberFormat working, it seems like it can't parse its
own output.
I have copied following from the watch-panel in Eclipse:
/*
* NumberFormat decimalFormat =
com.google.gwt.i18n.client.NumberFormat.getDecimalFormat();
*/
"decimalFormat.format(1234.5)"= "1 234,5"
"decimalFormat.parse("1 234,5")" => java.lang.NumberFormatException!?
"decimalFormat.parse("1.234,5")" => java.lang.NumberFormatException
"decimalFormat.parse("1,234.5")" => java.lang.NumberFormatException
"decimalFormat.parse("1 234.5")" => java.lang.NumberFormatException
"decimalFormat.parse("1234,5")"= 1234.5
"decimalFormat.getPattern()"= "#,##0.###"
NumberConstants of my locale:
/*
* NumberConstants numberConstants = GWT.create
(NumberConstantsImpl.class);
* (NumberConstantsImpl_cs)
*/
"numberConstants.decimalSeparator()"= ","
"numberConstants.groupingSeparator()"= " "
"numberConstants.monetarySeparator()"= ","
"numberConstants.monetaryGroupingSeparator()"= " "
I assume following does not matter but just in case...
...this is how my machine's OS formats numbers:
Number: 123,456,789.00
Currency: 123 456 789,00 Kč
...this is how the server's OS formats numbers:
Number: 123 456 789,00
Currency: 123 456 789,00 Kč
Am I missing something?

If I understand your issue correctly, I think you could make it work
by having your AWrapper constructor call
GWT.create(AWrapperImpl.class) and delegate all of AWrapper's methods
to the AWrapperImpl. That brings generators into the mix without
creating a burdensome API.
Make sense?

Code Licensing
This might not be the best forum for this question, but it specifically involves GWT code and should be simple, so I'll give it a shot. I'm in the process of taking classes from some Google-written GWT modules (both java and jsni code), mangling them, and writing code on top of the result. Obviously this is fine because of the original license, but as I post my code online (still under the Apache 2.0 License), I'm wondering what other people in a similar situation have done with the notice on the top of source files. Specifically, for those files that qualify as "Derivative works" but contain significant code copyrighted by Google, how have people best fulfilled their obligations to "2.

Re: GWT 2.0 - com.google.gwt.user.client.rpc.IsSerializable is mandatory again?
Hi all! I tested this behavior the last days, and remarked that this generated rpc file contains entries (as row) with all types that could be use during rpc call, all with "false" after it. It's not possible to set it back to true, since the gwt.rpc file is generated at any running. Is there a possibiliy to take control on the generation of this file.

UIBinder and image resources
Starting point:
http://code.google.com/webtoolkit/doc/latest/DevGuideUiBinder.html#Using_an_external_resource
My goal here is simply to bind an image, and update it later on if
necessary. I implemented the following code as a first step, but I
keep getting "Found widget in an
HTML context". I'm unsure as to what that means; does the container
need to be initialized somehow?
Any pointers appreciated.
Code:
public class Sandbox implements EntryPoint {
public void onModuleLoad() {
BinderUiTest test = new BinderUiTest();
Document.get().getBody().appendChild(test.getElement());
}
}
public class BinderUiTest extends UIObject {
interface MyUiBinder extends UiBinder {}
private static MyUiBinder uiBinder = GWT.create(MyUiBinder.class);
@UiField(provided = true)
final Resources resources = Resources.INSTANCE;
public BinderUiTest() {
setElement(uiBinder.createAndBindUi(this));
}
}
public interface Resources extends ClientBundle {
Resources INSTANCE = GWT.create(Resources.class);

JAXB in model classes also used by GWT RPC
I have about 20 "model" classes that I use with GWT RPC and also persist into a database using JPA. This is all working fine. On the server side I need to do some XML processing and would like to use some JAXB annotations on these model classes. However it complains with: 15:26:47.005 [ERROR] [gwtui] Line 18: The import javax.xml.bind cannot be resolved Is there any way of getting this to work? Why does it like my JPA annotations just fine but reject the JAXB ones? How have other people structured their projects that use GWT, databases and webservices?

Re: Multiple domains from a single servlet container
You could create multiple domain names (one for each client) that all map to the same IP Address. In your servlet, based on the domain name figure out the right database to read from.

Re: Page back color
Thing is, if you set the style name to "MyStyleName" then there is no
corresponding .MyStyleName in the GWT styles to override it.
There is a body{} in there though and if you are including your style sheet
from the html file (say with a ) then it will get overridden by the
GWT style sheet which is included (later) from the gwt.xml file.
For example, the standard GWT css file has
background: #ffc;
for the body.
Two things:
1) Are you including your css from the html file?
2) Does your gwt.xml file include a GWT style sheet e.g. ?

Re: Any easy way to tell which file is for which permutation?
Its not that difficult, actually.
When you use -style PRETTY, your nocache.js has a code fragment similar to
try {
unflattenKeylistIntoAnswers(['opera'],
'34478C007220DB07F52AB22169457501');
unflattenKeylistIntoAnswers(['ie6'],
'872904FEB2B0C8ABFEEF5D761EE7FEF4');
unflattenKeylistIntoAnswers(['safari'],
'B30F09E1C9B5B042E928F79F73C1C79B');
unflattenKeylistIntoAnswers(['gecko1_8'],
'B712029A53D248F96310715A52A54CBA');
unflattenKeylistIntoAnswers(['gecko'],
'BAAA33CCD5FA4984C7DB8207E830D268');
unflattenKeylistIntoAnswers(['ie8'],
'C1B0450CB888E93E17495AEDAE49EB45');
strongName = answers[computePropValue('user.agent')];
initialHtml = strongName + '.cache.html';
}
catch (e) {
return;
}
and that is the answer to your question.

Question on Code Generation inconjunction with JS-Libraries to optimize size
Hi,
I've been banging my head against something people here might probably
be able to help me. I've written a wrapper for a extensive JavaScript
Library which itself has a toolchain to optimize JS-Script code by
analyzing the used JS-API.
As a small example say the js-library has:
* a.js
* b.js
* c.js
And my wrappers look like this:
---8<---
AWrapper {
// ...
}
BWrapper {
// ...
}
CWrapper {
// ...
}
---8<---
Now my problem is that if I want to use it with GWT I need to findout
which Wrapper-Classes the GWT application uses, spit out informations
I can feed into the external toolchain to create an optimized JS-
Library-Version.
I thought about using the GWT Code Generation to get informed whenever
wrapper classes are used but as far as I understood this code
generation only jumps in when I use GWT.create() but this means my
Library users need to use GWT.create(AWrapper.class) instead of "new
AWrapper()" which is not very natural.
My ideal thing would be to have annotate my Java-Wrappers with
something like this:
---8<---
@JSResource("a.js")
AWrapper {
// ...
}
@JSResource("b.js")
BWrapper {
// ...
}
@JSResource("c.js")
CWrapper {
// ...
}
---8<---
And somehow plug myself into the GWT-Compiler toolchain and get
informed when ever such a class is visited similar to what would
happen when I use GWT.create(). Does anybody have an idea or a
document, example source I can read though myself?

Assuming you module is named hangman, this line

Do you have some kind of GWT style overriding it?
Have a look in your project gwt.xml file. If you are adding css in the html
host page, the it will be overridden by that.

JDO Error?
I have programmatically created two data objects, which I have validated
through the admin tool, and then attempt to delete them using this code:
try
{
pm.currentTransaction ().begin ();
List list = (List) pm.newQuery
(query).execute ();
if (!list.isEmpty ())
{
int real_count = 0;
int count = list.size ();
for (StreamingMetaData d : list)
{
long id = d.getID ();
if (id > 0)
{
pm.deletePersistent (d);
real_count++;
}
}
}
pm.currentTransaction ().commit ();
}
catch (Exception e)
...
but when it gets to the second object, the following JDO code throws an
"internal error" exception. Any thoughts?
/**
* JDO Convenience method to wrap any DataNucleus exceptions for the
deletePersistent process.
* @param obj The object to delete
* @throws JDOUserException thrown if the object could not be deleted
*/
private void jdoDeletePersistent(Object obj)
{
try

When I click on an specific radio button in my application the application seems to hang (the "please wait" indication remains displayed). This problem occurs in Chrome, FF and IE. In IE an JS error appears which says: line 2965 char 368 Error 'b.a' is null or not an object Code:0 URL: .cache.html I use GWT-EXT and my application is hosted on Google App Engine. Does anybody seen this error before and give me some pointers where to look ? regards Wouter -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: GWT 2.0: Plugin failed to connect to hosted mode server
Hi Chris Yes - using localhost:9997 did solve the problem! Thank you. I could create the project before but not debug it - it didn't even call the Java code, as I explained it showed only the static HTML. Can you explain the difference?

Problems with generator
am implementing a generator to generate code using Apache Velocity.
The question is that you use the JClassType.getMetaData () to get the
annotations in the code. Some extraction of my code:
GearsDataStoreGenerator extends Generator{
public String generate (TreeLogger logger,
GeneratorContext context, String typeName) throws
UnableToCompleteException
{TypeOracle typeOracle = context.getTypeOracle();
JClassType requestedClass = typeOracle.getType(typeName);
requestedClass.getMetaData(ANNOTATION_TABLE); // GWT 1.7
returns the annotation metadata! GWT 2.0 returns nothing!
So GWT 1.7 version works perfect. But from version 2.0 stopped
working. Reading the sources of the method I detected the following
change:
GWT 2.0
@Deprecated
public final String[][] getMetaData(String tagName) {
return TypeOracle.NO_STRING_ARR_ARR;
}
GWT 1.7
public abstract String[][] getMetaData(String tagName);
In the context help of the method, talks about how to replace it:
...
@deprecated
Javadoc comment metadata has been deprecated in favor of proper Java
annotations. See HasAnnotations.getAnnotation(Class) for equivalent
functionality.
Someone could help me with some example of
HasAnnotations.getAnnotation
(Class) ??
It think I have to use @Target(ElementType.ANNOTATION_TYPE)?

StatusCodeException
Mac OS X 10.5.7 Firefox 3.5 Eclipse 3.5 Galileo Cocoa Java 1.5.0 GWT 2.0 Hello, I'm catching a StatusCodeException when I try to make an RPC call. The method getStatusCode() is indeed returning 0 which I understand means that the server can not be reached. But I've been able to connect to the server at various times in development. I'm usually able to actually but every now and then I see this. I've tried restarting the computer, restarting the server, and I've recompiled my project. If someone could help me debug why the server can not be reached I'd appreciate it. Thanks. -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Validating ClientBundles ?
Hi, After upgrading the Eclipse plugin to GWT 2.0, whenever I import my Eclipse projects, Eclipse crashes. After importing the projects, I see multiple multiple (~12) jobs spawned called "Validating ClientBundles", then it either shows a warning saying that it ran out of memory or just closes. When inspecting the Eclipse log, I found this: !ENTRY org.eclipse.core.jobs 4 2 2009-12-22 11:07:17.178 !MESSAGE An internal error occurred during: "Refreshing workspace". !STACK 0 java.lang.OutOfMemoryError: unable to create new native thread at java.lang.Thread.start0(Native Method) at java.lang.Thread.start(Thread.java:597) at org.eclipse.core.internal.jobs.WorkerPool.jobQueued (WorkerPool.java:145) at org.eclipse.core.internal.jobs.JobManager.schedule(JobManager.java: 1001) at org.eclipse.core.internal.jobs.InternalJob.schedule (InternalJob.java:391) at org.eclipse.core.runtime.jobs.Job.schedule(Job.java:435) at com.google.gdt.eclipse.core.BuilderUtilities.revalidateCompilationUnits (BuilderUtilities.java:170) at com.google.gwt.eclipse.core.clientbundle.ClientBundleResourceChangeListener $1.visit(ClientBundleResourceChangeListener.java:154) at org.eclipse.core.internal.events.ResourceDelta.accept (ResourceDelta.java:68) at org.eclipse.core.internal.events.ResourceDelta.accept (ResourceDelta.java:79) at org.eclipse.core.internal.events.ResourceDelta.accept (ResourceDelta.java:79) at org.eclipse.core.internal.events.ResourceDelta.accept (ResourceDelta.java:79) at org.eclipse.core.internal.events.ResourceDelta.accept (ResourceDelta.java:79) at org.eclipse.core.internal.events.ResourceDelta.accept (ResourceDelta.java:79) at org.eclipse.core.internal.events.ResourceDelta.accept (ResourceDelta.java:79) at org.eclipse.core.internal.events.ResourceDelta.accept (ResourceDelta.java:79) at org.eclipse.core.internal.events.ResourceDelta.accept (ResourceDelta.java:48) at com.google.gwt.eclipse.core.clientbundle.ClientBundleResourceChangeListener.visitResourceDelta (ClientBundleResourceChangeListener.java:124) at com.google.gwt.eclipse.core.clientbundle.ClientBundleResourceChangeListener.resourceChanged (ClientBundleResourceChangeListener.java:116) at org.eclipse.core.internal.events.NotificationManager$2.run (NotificationManager.java:291) at org.eclipse.core.runtime.SafeRunner.run(SafeRunner.java:42) at org.eclipse.core.internal.events.NotificationManager.notify (NotificationManager.java:285) at org.eclipse.core.internal.events.NotificationManager.broadcastChanges (NotificationManager.java:149) at org.eclipse.core.internal.resources.Workspace.broadcastPostChange (Workspace.java:313) at org.eclipse.core.internal.resources.Workspace.endOperation (Workspace.java:1022) at org.eclipse.core.internal.resources.InternalWorkspaceJob.run (InternalWorkspaceJob.java:45) at org.eclipse.core.internal.jobs.Worker.run(Worker.java:55) === These are my JVM settings in eclipse.ini: --launcher.XXMaxPermSize 256m -Xms256m -Xmx1024m -Xss1024k Is there a way to turn off this validation upon importing the project.

Problems reading the content of a text file.
Hi!
I'm doing an example that I found ina book about GWT. It's the typical
example of the hangman. I'm using Eclipse and GWT 2.0. This is my
code:
public class AhorGwt implements EntryPoint {
private FlowPanel letters = new FlowPanel();
private Label wordLabel = new Label();
private Image image = new Image();
private final int MAX_GUESSES = 6;
private int misses;
private String[] words;
private String word;
private char[] visibleWord;
@Override
public void onModuleLoad() {
//create interface
RootPanel ahorcado = RootPanel.get("ahorcado");
ahorcado.add(letters);
ahorcado.add(image);
ahorcado.add(wordLabel);
//load words
final RequestBuilder requestBuilder = new RequestBuilder
( RequestBuilder.POST, "movies.txt" );
try {
requestBuilder.sendRequest( null, new
RequestCallback(){
public void onError(Request request, Throwable
exception) {
GWT.log( "failed getting movie list",
exception );
}
public void onResponseReceived(Request request,
Response response)
{
words = response.getText().split("\n");
GWT.log(words[2], null);
startGame();
}} );
} catch (RequestException e) {
GWT.log( "failed getting movie list", e );
}
wordLabel.setStyleName("word");
}
// ...
}
My movies.txt file is under /war/ file next to my index.html. Ok, once
I get the supossed text file into 'words' variable I do a 'GWT.log
(words[2], null);' in the console developent mode of eclipse I get
this "HTTP Status 404 - Status report". As you can see, the file
movies.txt hasn't been loaded. Instead of this, the program has red a
kind of default text/html file. I don't know if the problem is in the
location of the file or If I'm using a wrong method to read files on
the client side.
Thanks,
Juanma

Re: UI Binder bugs - maybe config issue on my side(?)
Peter, Also, would you mind downloading a fresh copy of Eclipse (with a new workspace) for testing purposes? I imported your project, and the @UiFields are not marked as errors for me. If a fresh Eclipse works, it'll help in debugging whether it's a system configuration issue or an Eclipse configuration issue.

Re: MVP Beginner Question
We've just added a tech article related to building GWT-based apps using the MVP architecture.

Re: GWTShell dev mode problem
Hi Shawn, I'm not sure how those Android natures/builders were added to your project. Maybe you inadvertently triggered a wizard that creates a GAE + Android project, or some other wizard that converts your project to an Android project? At any rate, to remove the "Androidness" from your project, remove the following entries from the file: org.eclipse.ui.externaltools.ExternalToolBuilder full,incremental, LaunchConfigHandle/.externalToolBuilders/com.android.ide.eclipse.adt.ResourceManagerBuilder.launch org.eclipse.ui.externaltools.ExternalToolBuilder full,incremental, LaunchConfigHandle /.externalToolBuilders/com.android.ide.eclipse.adt.PreCompilerBuilder.launch org.eclipse.ui.externaltools.ExternalToolBuilder full,incremental, LaunchConfigHandle /.externalToolBuilders/com.android.ide.eclipse.adt.ApkBuilder.launch com.android.ide.eclipse.adt.AndroidNature On Mon, Dec 21, 2009 at 5:38 PM, Shawn Brown wrote: > Hi Miguel, > > > Is the war directory at the root of your project? > yes > > >If you look at your .project file does it have the web app nature? > > Can you post what a .project file should look like?

Re: New layouts not playing nicely with Maps
I am using UI binding to setup my app, so I needed a little extra
tweak to Eric's code.
If I placed the timer either before or after the createAndBindUi call
in my widget containing the map, I was still experiencing the map UI
rash Jeff and Andrew had.
However, since my app also uses event handling (via gwt-dispatch), I
was able to fire a custom RetrievedMap event at a place in the code
when I know the app has completely finished UI binding (ie, the user
clicks on a nav item to fetch map data, the app retrieves a success
from the server, the app then fires the RetrievedMap event ). My
docker widget containing the MapWidget listens for the RetrievedMap
event, and so I tucked in Eric's timer code to the method handling the
RetrievedMap event and it worked wonderfully.
Phew. What I am trying to say is: if you are using UI binding, a plain
Timer fix may not work because of arbitrary times that your UI may
complete binding. Best to fire an event when you know the UI is
completely loaded, and in handling the event run Eric's timer code.

Pressing the enter key in the SuggestBox popup fire onKeyUp event! How to disable this?
Hi there!
If I select an option in the SuggestBox popup by pressing the enter
key then onKeyUp event fire. But I don't want that it happens because
I already handle pressing the enter on the textbox by executing
another code. My code below:
suggestBox.addSelectionHandler(new SelectionHandler() {
public void onSelection(SelectionEvent
arg0) {
//Here my code
}
});
suggestBox.getTextBox().addKeyUpHandler(new KeyUpHandler() {
public void onKeyUp(KeyUpEvent arg0) {
if (arg0.getNativeKeyCode() == 13) {
//Here another my
code
}
}
});
How to disable this or what is the workaround?

GWT 2.0: Plugin failed to connect to hosted mode server
Hello everybody, I am new to GWT and need some help. I have recently downloaded GWT 2.0 as an Ecplise plugin + SDK. Following the "Getting started" tutorial I have created a new GWT application project in Eclipse, StockWatcher. I have made no changes to the generated application. The application was created successfully, so I tried to run it locally using "Run As -> Web Application" (with the Google icon). Then I copied the suggested URL from Development Mode tab and pasted into the browser (Chrome 4 with GWT extension): http://localhost:/StockWatcher.html?gwt.codesvr=10.0.0.1:9997 I was expecting to view the default page normally, but it turned out that only the static elements of the web page (the headline "Web Application Starter Project" and label "Please enter your name:") were displayed. After a while, a message box pops up: "Plugin failed to connect to hosted mode server at 10.0.0.1:9997". When I close it I get a blackened screen with: "GWT Code Server Disconnected Most likely, you closed GWT development mode. Or you might have lost network connectivity. To fix this, try restarting GWT Development Mode and REFRESH this page." This of course happening each time no matter what I do. Then I tried to compile the project and go directly to http://localhost:/StockWatcher.html , without the gwt.codesvr parameter. It did work, but that means that I can only work by compiling the code each time I want to test it (and probably can't debug). At first I thought this might be a firewall issue (although i'm not sure that accessing localhost should be a firewall concern), but to be on the safe side I have opened the ports and 9997. It didn't help. Any ideas? Thanks, Yuval -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Making a GWT HTTP listener service for accepting external request
Hi all, I've tried looking at the documentation on how to create a GWT HTTP service that will listen to a request from another webapp but I'm having a hard time on how to implement it. What I've found in the docs is either: - GWT calling external HTTP service - or GWT calling internal RPC service Is there any docs or article on how to do this in GWT that I can read? Or maybe someone can give me a short hint on how to implement it?

Re: Developing a plugin based application
Hi,
I recently had very similar problem. I have an app in which there are
Views (similar to your layers) and I wanted views to be completely
independent of the App (before I made the changes the App's class was
responsible for creating Views which I found very sloppy). I did
pretty much the same thing that Eric has proposed. The App's class has
a static list of Initializers which implement Initializer interface
which have two methods, first creates associated View's instance and
second adds itself into the App's list of Initializers so the App only
goes through the array and calls newInstance of each initializer. The
initializers implements EntryPoint so I can specify which Views to
create simply by adding a module to my gwt.xml or by adding more
EntryPoints to it. I don't know if this is right method to implement
this but I'm using it together with code splitting and everything
seems fine (View's code and App's code are put in deferedjs and only
very small portion of code is executed in JS after the app startup
which speeds the initial loading time). After calling GWT.runAsync the
App properly initializes all registered views.

SyncInterface
Hi, We would like to automatically generate the AsyncInterface for a service inside an ant task (for example, could be anything else!). The point is that our async interfaces can, effectivally be generated automatically and doing it class by class inside eclipse with the google plugin in very boring and error prone...

Re: UnsatisfiedLinkError on Production Machine
You're trying to call a JSNI method on the server. That won't work. You get an UnsatisfiedLinkError because JSNI uses Java's native method syntax. On the server there is no native implementation of that method. You'll need to use a different MD5 implementation on the server.

I'd suggest removing the plugins (all versions) from the "dropins" and
try installing the 1.2 plugin from the install site if possible (and
why not take GWT 2.0 from there too when you're at it?).
Otherwise, start from a fresh workspace, and as a last resort from a
fresh Eclipse install.

This is a hack but if you really want it:
- use a form
- expose a GWT method as a JS 'global' function (e.g.,
myExportedGwtMethod)
- set the form's action to call the exported method
("javascript:myExportedGwtMethod()")
- do your XHR/RPC call from within your exported GWT method
Note that (I'm almost sure this isn't the case, for any form except
login forms, but just in case) this might only work if the form is
actually part of the original HTML markup of the page (i.e. not
inserted by script).
It's not worth it IMO; except for login forms eventually, even if it
goes against the most basic security rules, just because of the
enhanced UX.

Problem upgrading Eclipse for 2.0
I'm trying to upgrade to GWT 2.0. I downloaded the latest version of
the Eclipse plug-in (1.2) and tried to install it, by extracting it
into the dropins directory, but that didn't seem to work (couldn't add
the new SDK because the old plug-in was saying it didn't contain a jar
file with a platform extension).
I then did something that was probably kind of stupid and tried
deleting the old version of the plug-in (1.1.1) from that directory.
New version still didn't load. To try to put things back I copied all
the old 1.1.1 files back into dropins but Eclipse still gives me
errors when I try to open up a project that was working before this
whole adventure ("Could not open the editor: No editor descriptor for
id com.google.gwt.eclipse.core.editors.gwtJavaEditor").
Any ideas how I get this all sorted back out?
Thanks a lot,
Brandon

Saving form inputs for browser autocomplete
Hi all, I am curious about, how can one enable, or force a browser to remember value inside text inputs (TextBox) values. In browsers it basically works when you submit a form, then all values are remembered, and next time you open that form, you will be provided with autocomplete box. All major browsers works like this. Since in apps, that decides to use XML, JSON or GWT RPC, values in forms are actually not submitted, and thus not remebered. We just read those values and don't do any submit, we do XHR instead. Any ideas how to get back this very useful browser feature? -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: Development mode crashes Safari 4.0.4 in OS X 10.4
The issue appears to be with 10.4 and the browser plug-ins, not GWT 2.0 on 10.4 itself. A slightly rubbish workaround is to install a Linux or Windows virtual machine (VirtualBox works fine) and install the GWT plug-in into the browser on Linux/Windows. Luckily my main machine is running 10.6 :) -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

If you are tired to write Actions and Results you may consider using the RPC the old way, nothing is gonna constrain you.

Re: UI Binder bugs - maybe config issue on my side(?)
Sure, thanks for helping hand. Zipped project is here:
ns.blucina.net/lovisek/tmp/XploreU-inbox.zip
I also deployed the project here:
http://ns.blucina.net/lovisek/tmp/xu/XploreU_inbox.html
As you can see, onClick handler is never fired despite it should be
triggered after clicking on button and bold C label.

Peter

So what would you suggest? 1. Overriding insertItem, etc and firing a ChnageEvent (I has a quick look and I can't see how)? 2. Overriding insertItem, etc and implementing my own change handler interface? 3. Something else?
