Adding and removing items

I'm trying to remove a button, and replace it with another component,
when a specific event happens.

The following code doesn't seem to work correctly, what am I missing?

import javax.swing.*;
import java.awt.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

public class Test implements Runnable {
  JPanel[] panels;
  JButton[] buttons;
  public void run() {
    panels = new JPanel[3];
    buttons = new JButton[panels.length];
    for (int i = 0; i < panels.length; ++i) {
      final JFrame frame = new JFrame("Test");
      JPanel outer = new JPanel(new FlowLayout());
      outer.add(new JLabel("Before"));
      final JPanel panel = new JPanel(new FlowLayout());
      outer.add(panel);
      outer.add(new JLabel("After"));
      frame.add(outer);
      final JButton button = new JButton("Click to remove");
      panel.add(button);
      panels[i] = panel;
      buttons[i] = button;
      button.addActionListener(new ActionListener() {
        public void actionPerformed(ActionEvent e) {
          removeAllButtons();
        }
      });
      frame.setLocationByPlatform(true);
      frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
      frame.pack();
      frame.setVisible(true);
    }
  }
  private void removeAllButtons() {
    for (int i = 0; i < panels.length; ++i) {
      panels[i].remove(buttons[i]);
      panels[i].add(new JLabel("Added"));
      panels[i].repaint();
    }
  }

  public static void main(String[] args) {
    EventQueue.invokeLater(new Test());
  }
}
