JTable - removing row
Hello.
I am using a JTable that needs to have rows added and removed.
To remove the last row of the table I use the line:
Def_model.removeRow( table.getModel().getRowCount() - 1 );
Def_model is a DefaultTableModel and table is a JTable
After I removed the line I could do select another cell (with the mouse) the folowing exception was trown:
Exception in thread"AWT-EventQueue-0" java.lang.ArrayIndexOutOfBoundsException: 21 >= 21

I did not understood what was hapenning. Ther is no reference to the class I was creating in the exception. What was I doing wrong?
Well, i had a KeyListener added to the DefaultCellEditor's Component. In the KeyListener i had a System.out.println( "MyClass etc... that was sending output every time a key was pressd, even after the line i was editing was removed. I changed My code for:
editor.stopCellEditing();
Def_model.removeRow( table.getModel().getRowCount() - 1 );
editor is a DefaultCellEditor object.
With this code every thig works fine.
It seem to me that JTabledo not stop editing a cell even if the line it was in was REMOVED.
Is this the expected behavior? I did not find any reference on this in the documentation.
This situation is very hard to debug because the exception is not trown from programers class.
Is this a swing bug?
