Hi Mic

I got your issue. I was also facing the same issue. Actuially when you are
dragging any item and droping the same into another container then you are
using the same instance means that in drop target you are giving the same
reference of the dragged item.

You need to just create a new instance of the dragged item while dropping
and add it to the drop container.

Then it will not remove from your previous container. And in case of right
drop container, remove the item from the dragging container.

Hope this helps

Regards
Gagan Deep
