Hi,

given the following code:

public class DialogTest implements ActionListener {
  public static void main(String[] args) {DialogTest g = new DialogTest();}

  public DialogTest() {
    JButton b1 = new JButton("Button A");
    b1.addActionListener(this);
    JDialog d = new JDialog();
    d.setDefaultCloseOperation(JDialog.DISPOSE_ON_CLOSE);
    JPanel p = new JPanel();
    p.add(b1);
    d.add(p);
    d.getRootPane().setDefaultButton(b1);
    d.pack();
    d.setVisible(true);
    d.dispose();
    d.pack();
    d.setVisible(true);
  }

  public void actionPerformed(ActionEvent e) {System.out.println("hello");}
}

Shouldn't pressing the Enter key write something to the console? According to the docs (http://java.sun.com/javase/7/docs/api/java/awt/Window.html#dispose()):

The Window and its subcomponents can be made displayable again by rebuilding the native resources with a subsequent call to pack or show. The states of the recreated Window and its subcomponents will be identical to the states of these objects at the point where the Window was disposed

Is this intended behaviour?
