I have not been following this discussion very closely, but what
is your bug and which version of swing are you running?
As far as I can tell, with JDK1.2.2 updating selected cells in
a table works splendid. As well as the not selected cells. :-)
A small demo that you can check if it works on your system, Lenny.
If this does not work on your system
It is a bit blunt since I am not invoking the event on the actual
swing-thread which it should be.
