validate() has no effect

[Rosie Vogel]

I have written an applet where two labels and two textfields need to be removed after the user clicks a certain button. I can't get it to work. When the button is clicked nothing happens...
Here's what I have made:

import java.awt.*;
import java.awt.event.*;
import java.applet.*;
public class VluchtApplet extends Applet implements ActionListener
{
  private GridBagConstraints gbc = new GridBagConstraints();
  private Label labEmail = new Label("Email address");
  private TextField fieldEmail = new TextField(30);
  private Label labWw = new Label("Password");
  private TextField fieldWw = new TextField(30);
  private Button butIl = new Button("Log in");
  public void init()
  {
    // Set up gridbaglayout
    setBackground(new Color(255, 237, 199));
    setLayout(new GridBagLayout());
    gbc.fill = GridBagConstraints.NONE;
    gbc.anchor = GridBagConstraints.WEST;
    gbc.weightx = 0;
    gbc.weighty = 0;
    Insets insets = new Insets(10, 10, 10, 10);
    gbc.insets = insets;
    // Log-in section
    addWithGbc(labEmail, 0, 0, 1, 1);
    addWithGbc(fieldEmail, 1, 0, 1, 3);
    addWithGbc(labWw, 0, 1, 1, 1);
    addWithGbc(fieldWw, 1, 1, 1, 2);
    butIl.addActionListener(this);
    addWithGbc(butIl, 3, 1, 1, 1);
    
    // Stuff that's irrelevant 
  }
  public void addWithGbc(Component comp, int x, int y, int rowspan, int colspan)
  {
    gbc.gridx = x;
    gbc.gridy = y;
    gbc.gridwidth = colspan;
    gbc.gridheight = rowspan;
    add(comp, gbc);
  }
  
  public void actionPerformed(ActionEvent ae)
  {
    if (ae.getSource() == butIl)
    {
      remove(labEmail);
      remove(labWw);
      remove(fieldEmail);
      remove(fieldWw);
      validate();
    }
  }
}

I know it seems kind of weird that you have to log in to an applet but it's an assignment for a class I'm taking so don't blame me

Any ideas? Thanks in advance!

Ignore my question, please. There was a mistake in my test. It's working now.
