TableCellRenderer woes

I have a table cell renderer that display a row differently depending
on whether it is selected. However, JTable does not seem to be smart
enough to repaint a row when it stops being selected or when it
becomes selected because of other rows being added or removed.

It there something to prod it, or it is up to me?

The solution is this:

/**
* abort any edit in progress
*/
private void stopEdit()
{
// stop any edit in process
TableCellEditor tce = jTable.getCellEditor();
if ( tce != null )
{
tce.stopCellEditing();
}
}

This must be called prior to anything that would sort, add, delete or
replace rows.
