JList with Checkboxes

Question

For my application, I require a JList with each row containing a text label, and two check boxes which can be checked or unchecked in the list. I have written the code below to render list elements in this way, however the checkboxes cannot be checked in the list. Is there something else that I have to do to enable this?
Code:
public class NodeListCellRenderer implements ListCellRenderer {
      * @see javax.swing.ListCellRenderer#getListCellRendererComponent(javax.swing.JList,
      *      java.lang.Object, int, boolean, boolean)
     public Component getListCellRendererComponent(JList list, Object value, int index, boolean isSelected,
               boolean cellHasFocus) {
          //Convert Value to node
          final Node n=(Node)value;
          //Create JPanel object to hold list element
          JPanel listElement=new JPanel();
          listElement.setLayout(new GridLayout(1,3));
          //Create Label to hold node name
          JLabel nodeName=new JLabel(n.toString());
          //Create checkbox to control trace
          final JCheckBox traceBox=new JCheckBox("Trace",n.isTraceEnabled());
          //Add Event Listener
          traceBox.addActionListener(new ActionListener() {
               public void actionPerformed(ActionEvent ae) {
                    n.setTrace(traceBox.isSelected());
          //Create Checkbox to control
          final JCheckBox failedBox=new JCheckBox("Failed",n.hasFailed());
          //Add Event Listener
          failedBox.addActionListener(new ActionListener() {
               public void actionPerformed(ActionEvent e) {
                    n.setFailed(failedBox.isSelected());
          //Colour All Components Grey if Selected
          if (isSelected) {
               nodeName.setBackground(Color.LIGHT_GRAY);
               failedBox.setBackground(Color.LIGHT_GRAY);
               traceBox.setBackground(Color.LIGHT_GRAY);
               listElement.setBackground(Color.LIGHT_GRAY);
          //Build List Element
          listElement.add(nodeName);
          listElement.add(traceBox);
          listElement.add(failedBox);
          return listElement;
}

Thanks for the pointer to that. I have created a mouse listener for my list, which in a very crude way is able to set the checkbox values on a list click, by changing the underlying objects that are stored in the list.
The problem that I'm having now is that if I click a checkbox in the currently selected list element, the value in the underlying object is set immediately, but the Checkbox does not update until i select another element in the list.
This seems to indicate that the getListCellRendererComponent method is not called when you click on the currently selected list element. Is there any way round this?
Here's my current mouse listener code:
list.addMouseListener(new MouseAdapter() {
               public void mousePressed(MouseEvent e) {
                    //get index of element clicked
                    int index=list.locationToIndex(e.getPoint());
                    //Get Element at Index
                    Node n=(Node)list.getModel().getElementAt(index);
                    /*Work out X position, if 33-66% of width, "trace" checkbox clicked
                    otherwise if >66% of width, "failed" checkbox clicked*/
                    if (e.getX()>(list.getWidth()*0.33) && (e.getX()<list.getWidth()*0.66)) {
                         n.setTrace(!n.isTraceEnabled());
                         list.revalidate();
                    } else if (e.getX()>(list.getWidth()*0.33)) {
                         n.setFailed(!n.hasFailed());
                         list.revalidate();
          });
