> 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;
> 		}
