Description

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;
}
