GWT 2.0 Javascript IE Crash

[Charlie M]

Hi All,

I have been recently testing out GWT 2.0 currently from the 2.0 branch
of the SVN although I have also tried Milestone 2. My app works fine
in Chrome and Firefox in both development and hosted modes.

When I try and run it in IE 6, 7 or 8 it complains of Javascript
errors. It complains of an "Invalid Argument" on the finally
statement.

The generated code is below:

function
com_google_gwt_core_client_impl_Impl_entry0__Ljava_lang_Object_2Ljava_lang_Object_2Ljava_lang_Object_2Ljava_lang_Object_2
(jsFunction, thisObj, arguments){
var initialEntry;
initialEntry = com_google_gwt_core_client_impl_Impl_entryDepth++ ==
0;
try {
return jsFunction.apply(thisObj, arguments);
}
finally {
initialEntry && (com_google_gwt_core_client_impl_SchedulerImpl_
$clinit__V() ,
com_google_gwt_core_client_impl_SchedulerImpl_runScheduledTasks__Lcom_google_gwt_core_client_JsArray_2Lcom_google_gwt_core_client_JsArray_2V
(com_google_gwt_core_client_impl_SchedulerImpl_FINALLY_1COMMANDS,
com_google_gwt_core_client_impl_SchedulerImpl_FINALLY_1COMMANDS));
--com_google_gwt_core_client_impl_Impl_entryDepth;
}
}

Does anyone have any ideas.

Thanks,

Charlie M

Would you mind entering an issue for this? Also, do you happen to have a the snippet of Java code that is resulting in the above JS?

I think the problem might lie with GWT core code. I can't see which
part of my code this relates to.

I have tried it in the the 2.0 RC and it sitll has the same problem.
Below is the Javascript call stack from IE.

> com_google_gwt_core_client_impl_Impl_entry0__Ljava_lang_Object_2Ljava_lang_Object_2Ljava_lang_Object_2Ljava_lang_Object_2
JScript anonymous function
gwtOnLoad
maybeStartModule
JScript anonymous function
JScript global code

Thanks,

One more thing of note is that DevMode in Eclipse then starts to take
close to 100% CPU.

I wonder if this is the bug that I am also seeing. I am running
2.0RC2 and in IE6 also get an Illegal Argument error when I run it as
compiled JS. From hosted mode this exception is thrown

stepping through the code my problem occurs in LayoutImplIE6 on the
line with the *


public Element attachChild(Element parent, Element child, Element
before) {
if (!isIE6) {
return super.attachChild(parent, child, before);
}

DivElement container = Document.get().createDivElement();
* container.insertBefore(child, before);


It works fine in IE7, 8, Safari and Firefox

I raised an issue for this a few days ago.

http://code.google.com/p/google-web-toolkit/issues/detail?id=4258

I have just worked out what causing it. Its a mistake in my code UI
XML. I had a colon in the width value. IE was throwing an exception
where as Firefox and Chrome were simply ignoring it.

Thanks,
