Capturing JCheckBox edit from within a JTable cell

Question

Hey,
I've gone through as many posts as i can from this forum and i have managed to understand quite a bit but there is just this one probelm that i have.
What i have is a checkbox in a cell in a jtable that causes the a jpanel elsewhere to repaint in various ways depending on whether the checkbok is checked or not.
The code below is for the table editor. The model is my table model. aCanvas is the panel being repainted. completeVisible is the array that aCanvas accesses to repaint the panel.
The code below works perfectly after the but only after the second click. the first 2 times i click the checkbox the value printed is true and then afterwards it starts alternating and working correctly... can anyone please tell me why this is?
thanks in andvance... :o)
private class TSPCellEditor extends AbstractCellEditor implements TableCellEditor, ActionListener {
          Boolean visible;
          JCheckBox check;
          String TEST = "TEST";
          public TSPCellEditor() {
               check = new JCheckBox();
               check.setActionCommand(TEST);
               check.addActionListener(this);
          public void actionPerformed(ActionEvent e) {
               if(TEST.equals(e.getActionCommand())) {
                    visible = new Boolean(check.isSelected());
                    fireEditingStopped();
          public Object getCellEditorValue() {
               return visible;
          public Component getTableCellEditorComponent(JTable table, Object value, boolean isSelected, int row, int column) {
               visible = (Boolean)(value);
               //boolean temp = visible.booleanValue();
               //temp = !temp;
               //visible = Boolean.valueOf(temp);
               check.setSelected(visible.booleanValue());
System.out.println(completeVisible[row]+" "+row);               
               completeVisible[row] = visible.booleanValue();
               model.setValueAt(visible, row, column);
               aCanvas.repaint();
               return check;
     }

I can't answer your question, but I think a better way to implement your solution is to use a TableModelListener. An event is fired whenver the contents of the table model are changed so you can do your processing here. This [url http://forum.java.sun.com/thread.jsp?forum=57&thread=418560]thread gives a simple example.
