How to have a JComboBox display an item different from the one selected

Question

Hello,
I have a JTable (single column). I have set this column cell editor to be a JComboBox...
JComboBox stdComboBox = new JComboBox();
TableColumn column_zero = stdTablewCombo.getColumnModel().getColumn(0);
        column_zero.setCellEditor( new DefaultCellEditor(stdComboBox) );I have added a lovString array say {"A", "B", "C") to this stdComboBox. However, when the user selects a value from this list, I need to display a value from another lovString array say {"1", "2", "3"}. So if the user selects A then 1 needs to be displayed.
I have a TableModelListener on this table that is getting me the correct selected index for any of the JComboBoxes on any of the rows. But I am little lost on how to display the value from the 2nd list.
Thanks.

Yes...but do I do that in the TableModelListener ?
This is what I've tried in the TableModelListener:
public void tableChanged(TableModelEvent e)
         System.out.println(e.getSource());
           if(e.getType() == TableModelEvent.UPDATE)
                TableModel model = stdTablewCombo.getModel();
                int row = e.getFirstRow();
                this.cellValue = ((String)model.getValueAt(row, 0));
                if (cellValue != null)
                     this.selectedIndex = this.stdComboBox.getSelectedIndex();
                      System.out.println("Selected Index:" + this.selectedIndex);
                      if (this.selectedIndex >= 0)
                         String valueToSet = this.lovStringB[this.selectedIndex];
                         model.setValueAt(valueToSet, row, 0);
                      else
                           System.out.println("Value in cell is not from List");
                      }It returns the selectedIndex value allright.
It sets the value of valueToSet string allright.
it also does the model.setValueAt allright....but this triggers a tableChanged event and it goes back up - this is also fine. However, when it now comes back to the this.selectedIndex = , this again returns the index of the original selection and not a -1 (for values not in the ComboBox list). This makes it go into an infinite loop and gives me a StackOverflowError.
