JXCollapsiblePane trigger with mouse

In SwingX examples that JXCollapsiblePane is used with a button, but I want to transfer it with mouse events. In my example, the JXCollapsiblePane closes at the beginning. Only when the user comes with the mouse on the button to open the JXCollapsiblePane. When the mouse leaves the area where the JXCollapsiblePane is supposed to crash again. My problem: JXCollapsiblePane is not reset when the mouse leaves the area using the button.

public class CollapsiblePaneDemo
{

  /**
   * @param args
   */
  public static void main( String[] args )
  {
    final JXCollapsiblePane cp = 
        new JXCollapsiblePane( JXCollapsiblePane.Direction.RIGHT );

    // JXCollapsiblePane can be used like any other container
    cp.setLayout( new BorderLayout() );

    // the Controls panel with a textfield to filter the tree
    JPanel controls = new JPanel( new FlowLayout( FlowLayout.LEFT, 4, 0 ) );
    controls.add( new JLabel( "Search:" ) );
    controls.add( new JTextField( 10 ) );
    controls.add( new JButton( "Refresh" ) );
    controls.setBorder( new TitledBorder( "Filters" ) );

    cp.add( "Center", controls );

    JXFrame frame = new JXFrame();
    frame.setLayout( new BorderLayout() );

    // Then the tree - we assume the Controls would somehow filter the tree
    JScrollPane scroll = new JScrollPane( new JTree() );
    // Put the "Controls" first
    frame.add( "Center", scroll );


    // Show/hide the "Controls"
    final JButton toggle = new JButton( cp.getActionMap()
        .get( JXCollapsiblePane.TOGGLE_ACTION ) );
    toggle.setText( "-" );
    toggle.setPreferredSize( new Dimension( 20, toggle.getSize().height ) );

    toggle.addMouseListener( new MouseAdapter()
    {
      @Override
      public void mouseEntered( MouseEvent e )
      {
        if ( cp.getSize().width == 0 )
        {

          toggle.doClick();
        }
      }
    } );

    final JPanel panel = new JPanel();
    panel.setLayout( new BorderLayout() );
    panel.add( "Center", toggle );
    panel.add( "East", cp );

    panel.addMouseListener( new MouseAdapter()
    {
      @Override
      public void mouseExited( MouseEvent e )
      {
        if ( !panel.contains( e.getPoint() ) )
        {
          toggle.doClick();
        }
      }
    } );

    frame.add( "East", panel );

    frame.setDefaultCloseOperation( JFrame.EXIT_ON_CLOSE );
    frame.pack();
    cp.setCollapsed( true );
    frame.setVisible( true );

  }
}
