JTable Cell Focus Problem

Question

I am using the setValueAt method in the TableModel of a JTable in order to do validation of the value the user has entered into a cell of a table (the validation involves looking at the values of other components on the same JFrame).
Everything works fine, except for the following case: The person enters a value into the cell of the editor. The person then moves the focus to another component via a mouse-click. The cell in the table still shows the new value entered by the person, but the setValueAt method is never triggered, and <table>.getValueAt(<row>,<col>) shows the value of the cell prior to the change.
Is there a way to ensure the setValueAt method of the TableModel is triggered before the JTable loses focus? Or is there a better (i.e. correct) way to accomplish this (ensuring a cell change is 'committed' to the table before
losing focus)?

Bug? What Bug? Sun considers this a feature....LOL
Here is my work-around:
   public boolean editCellAt(final int row, final int col, EventObject e) {
      if (e instanceof MouseEvent) {
         if (((MouseEvent)e).getClickCount()<2) {               // single click on a cell other than the one being edited causes editing to stop
            if (isEditing())getCellEditor(getEditingRow(),getEditingColumn()).stopCellEditing();
            return false;
      return super.editCellAt(row,col,e);                         // cell editing on a keyevent or a double mouse click
   }This is will if the mouse is clicked elsewhere on the same table. I have a lot of other tricks for JTable and things....check out my web site at:
