Conditional Drag and Drop

Hello,

I have a couple of JLabel with DnD functionality.
All works fine, but now I want implement a condition, so that Labels with
the same ID (ID is an object in the Transferable-object), do not accept a
drop on each other.
Only labels with a different ID can accept drops for a label.
Please give me some tips.

I think that you should:
1)supply custom DataFlavor (with label ID embedded)
2)your DropTarget should then check ID DataFlavor and accept or reject
drop according to ID
