I tried to setup a loaded event handler on a CLR class for a Shell widget as follows:

<Shell xmlns="www.eclipse.org/xwt/presentation" xmlns:x="www.eclipse.org/xwt"
	x:Class="br.rar.dups.Application" text="XWT Application" xmlns:p1="clr-namespace:br.rar.dups"
	loaded="onLoad">

If I specify the onLoad method as follows:

	public void onLoad(Application clr, Event event) {
		StackLayout layout =(StackLayout) XWT.findElementByName(clr, "stack");
	}

ResourceLoader updateEvent complains about not finding onLoad method...
in turn if I specify it as follows:

	public void onLoad(Shell widget, Event event) {
		StackLayout layout =(StackLayout) XWT.findElementByName(widget, "stack");
	}

updateEvent method finds the onLoad method but LoadingData inner class fails to execute the method on its end method since it tries to invoke the found method with the Application CLR class as parameter... resulting in an IllegalArgumentException with an almost blank catching code.

	public void onLoad(Event event) {
                Application clr = this;
		StackLayout layout =(StackLayout) XWT.findElementByName(clr, "stack");
	}

I know and I've been able to do a similar workaround but either both ways I've tried should work or should not throw an exception... it seems to me like the code in question is buggy...

BTW, be aware of bug report bugs.eclipse.org/bugs/show_bug.cgi?id=373668
