Hi there,

In my project I save objects to file. One such object I call Listbox. It
extends JScrollPane and its viewport contains a JList.
It looks like so:

public class Listbox extends JScrollPane implements InputTool, Serializable
{
  private JList list = null;
  private String id = "";
  private String[] values = null;
  private static final String[] EMPTY_ARRAY = new String[0];
  private boolean haveValues;
  private int item = 0; //default
  private InputType type = null;

  public Listbox()
  {
    list = new JList();
    super.getViewport().add(list);
    list.setVisibleRowCount(4);
    setPreferredSize(new Dimension(140,90));
    setMaximumSize(new Dimension(140,90));
    ItemListener listener = new ItemListener();
    list.addMouseListener(listener);
    setMultipleSelect(false);//default
  }

  ...
}

In my SaveFile() method using SwingUtilities.invokeLater() method (see
below), I can save all the objects to file alright, but the text in my
Listbox keeps disappearing.  I have tried calling repaint(), revalidate() on
both Listbox and the JList it contains, but neither works.  The text is
there, it just isn't showing after a save.  What am I doing wrong?
