Collapsible Pane not collapsing

[howudodat]

Not sure what I'm doing wrong. I'm adding some test collapsible panes. They show collapsed, but shouldn't they fold up like an accordian?

Code: Select all

      JPanel pnl = new JPanel();
      pnl.setLayout(new BoxLayout(pnl, BoxLayout.Y_AXIS));
      pnl.setPreferredSize(new Dimension(780,440));
      pnl.add(new JScrollPane(new PnlClientContacts()));
      pnl.add(new JButton("Another Panel"));
      pnl.add(new JButton("Another Panel 2"));
      return pnl;

public class PnlClientContacts extends JPanel {
   public PnlClientContacts() {
      initUI();
   }
   
   protected void initUI() {
      this.setLayout(new BoxLayout(this, BoxLayout.Y_AXIS));
      for (int x=0; x<10; x++) {
         CollapsiblePane panel = new CollapsiblePane("Filter");
         panel.setPreferredSize(new Dimension(100,100));
         panel.setSlidingDirection(SwingConstants.SOUTH);
         panel.setContentAreaFilled(true);
         panel.setTitle("Contact");
         if (x > 0) panel.collapse(true);
         this.add(panel);
      }
   }
}
