[flexcoders] Custom Container component and drag 'n drop support

[Weyert de Boer]

I have been working on a custom component which descends from the 
Container class. Now I am trying to implement drag 'n drop support.
I have enabled "dragEnabled"-property on my other List-component in the 
MXML file. I also have add the following listeners in my custom component:

            this.addEventListener( DragEvent.DRAG_ENTER , onDragEnter 
);       
            this.addEventListener( DragEvent.DRAG_DROP , onDragDrop 
);       
            this.addEventListener( DragEvent.DRAG_OVER, onDragOver );


Only the events never are getting triggered when I am hovering my list 
item over my component. How can I enable the dropping of items for my 
custom component?
Container doesn't seem to have a dropEnabled-property!

Thanks in avance!
