RE: [flexcoders] Drop Target indicator visibility issue

[Philip Smith]

Still experiencing the drop indicator visibility issue.

This method handles the 'dragOver event (and is executing):

private function onDragOver(de:DragEvent):void
  {
                de.preventDefault();
            
                var owner:List = this.owner as List;
                
                var dropLocal:DropLocation = 
owner.layout.calculateDropLocation(de);
                trace (dropLocal);
                
                owner.layout.showDropIndicator(dropLocal);
}

However, the drop indicator is not visible. I set a breakpoint in the code 
above and it appears the width of the drop indicator is 0...

Any ideas how to get this working?

Thanks.

      Currently experiencing a 'drop target indicator visibility' issue...



The drop target indicator is not visible when dragging an ItemRenderer in a 
Spark List with the following implementation: ( note the 'dragOver handler' 
(with 'layout.showDropIndicator' behavior) is in the 'onDragOver' method below):



<s:List itemRenderer="GroupItemRenderer"

                          dropEnabled="false"

                          useVirtualLayout="true"

                          width="100%">

                <s:layout>

                        <s:HorizontalLayout  />

                </s:layout>

</s:List>



GroupItemRenderer (referenced in the list above):



<s:ItemRenderer autoDrawBackground="true"

                dragOver="onDragOver"

                dragDrop="onDragDrop(event)",

                dragEnter="this.onDragEnter(event)"

<fx:Script>
