That's right but I wondered if there was another way.
Meanwhile I found something that works as well.
Using the itemrenderer allows to send the current data item back to
the calling container.
private function dispatchRowClickEvent(ev:ListEvent):void{
var e:ListEvent=new ListEvent('rowClick');
e.rowIndex=ev.rowIndex;
e.itemRenderer = ev.itemRenderer; // that does the trick
dispatchEvent(e);
}
