Swing frame not updating correctly

[Heatryn]

Hi guys.

I'm building a JFrame with on top of that a toolbar with a few buttons. I want to behave these buttons as "tabs" so when I click one of these buttons, the content of the BorderLayout.CENTER of the JFrame's contentPanel has to show the correct Panel.

Here is my code:

package view;

import javax.swing.*;

public class MainWindowMedewerker extends JFrame {
    private static final long serialVersionUID = 1L;
    private PanelLedenbeheer panelLedenbeheer = new PanelLedenbeheer();
    private PanelDomotica panelDomotica = new PanelDomotica();

    public MainWindowMedewerker(Gebruiker gebruikerAangemeld) {
	setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
	setTitle("Blauwe Regen");

	getContentPane().setLayout(new BorderLayout());
	
	JToolBar toolBar = new JToolBar();
	toolBar.setFloatable(false);
	toolBar.setRollover(true);
	getContentPane().add(toolBar, BorderLayout.NORTH);
	
	JButton btnLedenbeheer = new JButton("Ledenbeheer");
	btnLedenbeheer.addActionListener(new ActionListener() {
		public void actionPerformed(ActionEvent e) {
		    toonLedenbeheer();
		}
	});
	toolBar.add(btnLedenbeheer);
	
	JButton btnDomotica = new JButton("Domotica");
	btnDomotica.addActionListener(new ActionListener() {
		public void actionPerformed(ActionEvent e) {
		    toonDomotica();
		}
	});
	toolBar.add(btnDomotica);
    }

    private void toonDomotica() {
	//this.getContentPane().remove(panelLedenbeheer);
	this.getContentPane().add(panelDomotica, BorderLayout.CENTER);
	this.revalidate();
	this.pack();
	
	
    }

    private void toonLedenbeheer() {
	//this.getContentPane().remove(panelDomotica);
	this.getContentPane().add(panelLedenbeheer, BorderLayout.CENTER);
	this.revalidate();
	this.pack();
    }

}

However, when I click a third time one of these buttons, the layout isn't changing anymore.

What am I doing wrong?

I would advise you to use the CardLayout for this case:

Not in any way an 'advanced ' question either.
