How to extend JTable's TransferHandler in 1.4.1?

Question

Has anyone successfully extended a JTable's TransferHandler in 1.4.0 or 1.4.1beta?
Here is a simple working JTable DnD example but I need to be able to transfer data other than just strings (which is all that this example is designed to do) and the only way I can think of is to extend the TransferHandler (by default, in 1.4.1, JTable BasicTableUI has a TableTranserHandler class with a createTransferable method that is supposed to create a Transferable with various HTML tags but it doesn't seem to get called). I can't seem to do anything with the TransferHandler without clobbering the drag operation -- see bug report at the link shown below:
http://developer.java.sun.com/developer/bugParade/bugs/4514071.html
The bug shown above is supposedly fixed and closed but I think the problem still exists. I would appreciate anyone who can shed some light on this subject -- I've assign 5 dukes to this subject but if needed, I can assign more later.

Answer 1

Finally revisited this problem and found that it's a matter of putting the horse before the cart....i.e., TransferHandler has to be set before drag is enabled.
Consider ubject matter closed!
