Refreshing DefaultListModel does not repaint

I have a popup JDialog descendant. I right click to open the popup and that displays fine. When the dialog is refreshed by clicking the option again is has the effect of clearing the list. I show the code outline below. If I debug through the code _or_ include a simple showMessageDialog within the loop the dialog repaints correctly.

Any ideas what's going on?

public class MyDialog extends JDialog {

    private MyList sampleModel;

    public void Show(String msg){
          // populate list
          // refreshes correctly if include this message
          //JOptionPane.showMessageDialog(null,String.format("msg = %s",msg));

Thanks, Tom.
