Can't get rid of JDialog buttons!

Question

Hey all,
I just figured out how to use JDialogs and I'm having trouble with adding buttons on them. Specifically, once I kill the dialog, I want everything on it to go away so I can remake it again when I need to. However what happens is, when I re-add the buttons to the dialog, the old buttons are still there and I'm not sure why. Here's some of my code:
class JMenuAction extends AbstractAction
        private final JDialog d = new JDialog(new JFrame(),ResourceFile.getString("AddPlayerText"));
      //Constructors etc.
        public void actionPerformed(ActionEvent arg0)
            if(myKill)//remove everything
                System.out.println("HERE");
                getContentPane().removeAll();
                d.getContentPane().removeAll();
                d.removeAll();
                myButtons.clear();
            else if(myInstances<2 && myInstances>0)//Adding another player
                d.setLayout(new GridLayout(0,4));
                JButton one = new JButton(ResourceFile.getString("ComputerEasyCommand"));
                JButton two = new JButton(ResourceFile.getString("ComputerMediumCommand"));
                JButton three = new JButton(ResourceFile.getString("ComputerHardCommand"));
                JButton four = new JButton(ResourceFile.getString("EasyCommand"));
                JButton five = new JButton(ResourceFile.getString("MediumCommand"));
                JButton six = new JButton(ResourceFile.getString("HardCommand"));
                myButtons.put(one, new EasyComputerPlayer(myModel));
                myButtons.put(two, new MediumComputerPlayer(myModel));
                myButtons.put(three, new HardComputerPlayer(myModel));
                myButtons.put(four, new HumanPlayer(myModel,JottoModel.EASY));
                myButtons.put(five, new HumanPlayer(myModel,JottoModel.MEDIUM));
                myButtons.put(six, new HumanPlayer(myModel,JottoModel.HARD));
                ActionListener buttonAction = new ActionListener()
                    public void actionPerformed(ActionEvent e)
                        JButton source = ((JButton)e.getSource());
                        myPlayer = myButtons.get(source);
                        d.dispose();
                for(JButton b:myButtons.keySet())
                    d.add(b);
                    b.addActionListener(buttonAction);
                d.pack();
                d.setModal(true);
                d.setVisible(true);
                setUpView();
    }Is it because its final?

Answer 1

Is it because its final? No. Final only prevents the object reference of a variable from being changed.
Did you revalidate and repaint? If not, I recommend that you do these things.
I wonder if you need to use a CardLayout? I wonder if you just need to create a JDialog at the time it is needed and stuff the appropriate JPanel in it at that time?
