Drag and drop between a JList and a header table

[david zhang]

Hi, I am doing a Swing application now. I need to drag and drop between
a JList and the column header of a table. The header is a table too.
I set everything and can drag and drop from the list to the header.
However, there is no response such as mouse icon change when doing DnD
from the header to the list. None of the trasnfer handler's methods
ever got called (I put print statements in each of hander's methods).

Any idea and advice?

Thanks very much!
David
