Korrekte Art, ein JPanel zu serialisieren?

Question

Ich sende meine Klasse, die JPanel durch einen ObjectOutputStream zum Client erweitert, so dass ihre GUI 'geladen' wird.

public class ClickOptionPanel extends JPanel implements Serializable { 

private Font font = new Font("Arial", Font.BOLD, 13); 

private JLabel clickerTitle; 

private JSlider clickerMaxSlider, clickerMinSlider; 

private JTextField clickerMinField, clickerMaxField; 

private JCheckBox clickInsideMinecraft, autoBlock; 

public ClickOptionPanel() { 
    setLayout(new BorderLayout()); 
    add(getClickerTitlePanel(), BorderLayout.NORTH); 
    add(getClickerSliderPanel(), BorderLayout.CENTER); 
    add(getCheckBoxPanel(), BorderLayout.SOUTH); 
} 

private JPanel getClickerTitlePanel() { 
    JPanel panel = new JPanel(); 
    panel.setBorder(BorderFactory.createEtchedBorder()); 
    clickerTitle = new JLabel("Clicker Options"); 
    clickerTitle.setFont(font); 
    panel.add(clickerTitle); 
    return panel; 
} 

private JPanel getClickerSliderPanel() { 
    JPanel panel = new JPanel(); 
    panel.setLayout(new BorderLayout()); 
    clickerMaxSlider = new JSlider(0, 200, 125); 
    clickerMaxSlider.setPreferredSize(new Dimension(300, 45)); 
    clickerMinSlider = new JSlider(0, 200, 75); 
    clickerMinSlider.setPreferredSize(new Dimension(300, 45)); 
    panel.add(clickerMaxSlider, BorderLayout.NORTH); 
    panel.add(clickerMinSlider, BorderLayout.CENTER); 
    panel.add(getClickFieldPanel(), BorderLayout.SOUTH); 
    return panel; 
} 

private JPanel getClickFieldPanel() { 
    JPanel panel = new JPanel(); 
    clickerMaxField = new JTextField(10); 
    clickerMaxField.setFont(font); 
    clickerMaxField.setHorizontalAlignment(SwingConstants.CENTER); 
    clickerMinField = new JTextField(10); 
    clickerMinField.setFont(font); 
    clickerMinField.setHorizontalAlignment(SwingConstants.CENTER); 
    panel.add(clickerMinField); 
    panel.add(clickerMaxField); 
    return panel; 
} 

private JPanel getCheckBoxPanel() { 
    JPanel panel = new JPanel(); 
    panel.setLayout(new BorderLayout()); 
    panel.setBorder(BorderFactory.createEtchedBorder()); 
    clickInsideMinecraft = new JCheckBox("Only click inside of Minecraft:              "); 
    clickInsideMinecraft.setHorizontalTextPosition(SwingConstants.LEFT); 
    autoBlock = new JCheckBox("Enable auto-block:              "); 
    autoBlock.setHorizontalTextPosition(SwingConstants.LEFT); 
    panel.add(clickInsideMinecraft, BorderLayout.NORTH); 
    panel.add(autoBlock, BorderLayout.SOUTH); 
    return panel; 
} 

Da ist die JPanel, die ich sende. Ich erstelle eine neue Instanz davon, bevor es gesendet wird.

Das JPanel wird leer - warum ist das?

Ich habe alles richtig gemacht - es war nur, dass ich auf der Client-Seite vergessen habe, das ois.readObject Objekt auf dem Panel zu setzen!
