I am using a JComboBox as a JTable cell editor.  If the first item in the
list is
the current value and I reselect this value from the drop down list, the
combo box does not close.  The drop down list disappears but the combo box
is still visible. I guess that it is not telling the table that editing has
finished. Any suggestions?

I also have a JPanel as both a renderer and an editor for another column.  I
have placed JButtons on these panels.  The problem is that clicking on one
of the buttons causes it to be stuck in the down position.  It takes another
click to make it reset.  From this point on the buttons function correctly
(until another cell is selected).  I believe the problem is caused by mouse
clicks not being forwarded to the buttons until the cell is being edited
(after the first click).  Is it possible to put all cells in a column
permanently in the editing state.  Alternatively any other way of embedding
buttons in a table that allows them to work with one click would be
appreciated

Thanks,
Sam.
