Hello,
without source-code its difficult to understand where your problem is. The following sample code works 'fine':
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
public class AddCompoDialog extends JDialog {
     int compoCounter;
     public AddCompoDialog(){
          setLocationRelativeTo(null);
          setSize(300,300);
          JPanel mainPanel=new JPanel(new BorderLayout());
          JPanel buttonPanel =new JPanel();
          final JPanel compoPanel=new JPanel(new GridLayout(10,10));
          JButton newCompo=new JButton("add new Component");
          newCompo.addActionListener(new ActionListener(){
               public void actionPerformed(ActionEvent e){
                    compoPanel.add(new JLabel("Compo #"+ ++compoCounter));
                    compoPanel.revalidate(); //Dont forget to relayout your container
          buttonPanel.add(newCompo);
          JButton close=new JButton("close Dialog");
          close.addActionListener(new ActionListener(){
               public void actionPerformed(ActionEvent e) {
                    dispose();
          buttonPanel.add(close);
          mainPanel.add(buttonPanel,BorderLayout.NORTH);
          mainPanel.add(compoPanel);
          getContentPane().add(new JScrollPane(mainPanel));
     public static void main(String[] params) {
          new AddCompoDialog().setVisible(true);
}Regards,
