Don't add an ActionListener to the combo box, that is not the way an editor of the table was designed to be used.

Instead you should be adding a TableModelListener to the TableModel of the JTable. An event will be generated whenever data is changed in the table. The event will contain the row/column of the cell that was changed.

For a working example check out: TableModelListener and multiple column validation
