Hi!  I have problem to update JTable :
     I  put JProgressBar in a cell of JTable to indicate current progress.
So, I implemented TableModel and TableRenderer to update the JProgressBar.

   Whenever my data update, I invoked "fireTableRowsUpdated(..)" in
TableModel,
then it will call "getTableCellRendererComponent(...)" in TableRenderer.
The problem is when last row stop updating, all preveious rows will stop
too,
unless I resize the windows or select that row.  Debug shows me that when
last row stop updating,   "fireTableRowsUpdated(..)" won't invoke
 "getTableCellRendererComponent(...)" anymore, so all previous won't update.

     Can anyone help me out? Many thanks for you time!

My guess is that there is a bug in the event notification code, but there
is no way to be sure without seeing the code.  If you can post a runnable
example of the problem, I will be glad to look at it.
