Hi Karthik,
Where did u put the following function
public function DropTargetRenderer()
{
super();
this.addEventListener(DragEvent.DRAG_ENTER,dragEnterHandler);
this.addEventListener(DragEvent.DRAG_EXIT,dragExitHandler);
this.addEventListener(DragEvent.DRAG_DROP,dragDropHandler);
}
make sure u call this function in the constructor of the class you are
using it.
HTH,
-Ravi
