Justin Mclean commented on FLEX-33592:
--------------------------------------
Can you provide same sample code that shows the issue. Perhaps a better work
around is to stop the propagation of the click event in the click handler after
changing the data provider?
> mx.controls.MenuBar#getMenuAt RangeError

> Key: FLEX-33592

> Project: Apache Flex

> Components: mx: Menu Bar
> Affects Versions: Apache Flex 4.9.0
> Reporter: Philip Mair
> Original Estimate: 2h
> Remaining Estimate: 2h

> When changing MenuBar dataProvider within click on MenuBar-Item causes a
> RangeError in getMenuAt if the index was greater then new amount of MenuBar
> Items.
> I solved this with following workaround:
> public override function getMenuAt(index:int):Menu
> {
> var menu:Menu = null;
>
> try
> {
> menu = super.getMenuAt(index);
> }
> catch(e: Error)
> {
>
> }
> if(menu == null) //return a fake menu to avoid
> TypeError's
> return new Menu();
> else
> return menu;
> }
