[flexcoders] Re: Have a Spark List with an Itemrenderer

[Netaman]

I figured it out;

Add an addEventListener FlexEvent.UPDATE_COMPLETE to the List component, and in 
the event function;

         public function eventcalledfunction(event:FlexEvent):void {
             if (List.dataGroup.getElementAt(0) == null)
                 return;
             var newVar:ArrayCollection = new ArrayCollection();
             newVar = this.parentDocument.formArray as ArrayCollection;
             var i:int = 0;
             var j:int = 0;
             
             for (i=0;i<List.dataGroup.numElements;i++) {
                 var rRenderer:ListRenderer = List.dataGroup.getElementAt(i) as 
ListRenderer;
                 var rPanel:Panel = rRenderer.panelComponent as Panel;
                 rPanel.removeAllElements();
             }   
             
             for (i=0;i<newVar.length;i++) {
                 var sRenderer:ListRenderer = List.dataGroup.getElementAt(i) as 
ListRenderer;
                 var sPanel:Panel = sRenderer.panelComponent as Panel;
                 sPanel.addElement(newVar[i]); 
             }
         }
