Thanx for your help. I already figured it out. You need to call super.data = value; at the itemRender set data(value:Object) function in order to have selection working.
What you saw was a selection mecanism I was trying to program myself since the other one was not working
Here is the correct code:
override public function set data(value:Object):void {
super.data = value;
nameStr = value.name;
desc = value.desc;
menuItemData = value as MenuItemVO;
}
Hope this helps someone (or even you). And thanx again...
