How do I update a JTable immediately after editing a cell?

Question

I have a JTable where I use a JComboBox to select a value in a cell. When a value is selected this updates another cell in the JTable.
This works like I want to except for that I have to deselect the JComboBox (ie. click in another cell) before the other cell is updated.
I want the cell to be updated when the JComboBox changes without having to deselect the JComboBox first.
How can I do this?
Thanks in advance for any help...

As an example I just copied the TableRenderDemo from the Swing-tutorial (http://java.sun.com/docs/books/tutorial/uiswing/components/table.html).
The only change I have made to the TableRenderDemo is to replace the DefaultCellEditor with my own editor (ComboBoxEditor extends DefaultCellEditor).
The only change I have made to the program itself is therefore to replace
sportColumn.setCellEditor(new DefaultCellEditor(comboBox));*
with
sportColumn.setCellEditor(new ComboBoxEditor());*
(And add the class ComboBoxEditor, of course.)
When you run the original program, the default editor closes itself when a value is selected from the combobox. My editor doesen't close itself when a value is selected, but remais open until you click on another tablecell. I want my editor to close itself in the same way the DefaultCellEditor does.
The code for TableRenderDemo is here: http://java.sun.com/docs/books/tutorial/uiswing/examples/components/TableRenderDemoProject/src/components/TableRenderDemo.java
Again, to test what I mean just replace
sportColumn.setCellEditor(new DefaultCellEditor(comboBox));*
with
sportColumn.setCellEditor(new ComboBoxEditor());*
(And here is the code for my own celleditor:)
private class ComboBoxEditor extends DefaultCellEditor {
private JComboBox comboBox = null;
public ComboBoxEditor(){
super(new JComboBox());
@Override public java.awt.Component getTableCellEditorComponent(JTable table, Object value, boolean isSelected,int row, int column){
comboBox=new JComboBox();
String name=(String)table.getValueAt(row,0);
if(name.equals("Mary")){
comboBox.addItem("Marys sport");
comboBox.addItem("Marys cooking");
else{
comboBox.addItem("Other sport");
comboBox.addItem("Other cooking");
return comboBox;
//else return super.getTableCellEditorComponent(table,value,isSelected,row,column);
public void setCellEditorValue(Object newData){
comboBox = (JComboBox) newData;
@Override public Object getCellEditorValue(){
return comboBox;
}//end class
