sorry, but that's totally wrong - there is no guarantee whatsoever
that the editingRow/editingColumn is still valid at the time of a
focusLost. Additionally, the method getCellEditor(row, column) is
_not_ meant for being used while editing. It's meant to encapsulate
the strategy for choosing an appropriate editor _before_ starting an
edit.
The correct code for terminating an edit (using the approach to force
it in an focusListener is:
if (table.isEditing()) {
table.getCellEditor().stopCellEditing());
}
the if-check guarantees that getCellEditor returns the currently
active editor != null which is the only one you are interested in.
Note that at any time there is at most one editor active.
If there is some validation involved the editor might refuse to commit
the edited value by returning false from the stopCellEditing(). Then
additional processing is needed, depending on how you want to react to
that refusal - in 1.3 things are getting hairy then...
Happy holidays
