Just received an exception inside the following block:
----------------
function $Label(this$static, text){
$setElement(this$static, ($clinit_73() ,
$doc).createElement('div'));
(!!this$static.element || throwAssertionError_Object("This
UIObject's element is not set; you may be missing a call to either
Composite.initWidget() or UIObject.setElement()") , this
$static.element)['className'] = 'gwt-Label';
this$static.setText(text);
return this$static;
}
----------------
exception was thrown in 3rd line: (!!this$static.element ||....
This is plain GWT Label. It seems like a bug in GWT with Firefox
3.0.10
Unfortunately I can't reproduce it. Time after time it is thrown on my
client workstations. It is caught using
GWT.setUncaughtExceptionHandler.
Any ideas?
