Problem using the setPage(String url) of JEditorPane

Question

Hi all !
I'm developping a text file generator which generates a text file and use a viewer to display the content of this text file.
The first time, it works correctly, it displays the text file content but the others times it doesn't work correctly, the first text file content remains displayed.
It seems that the setpage(String url) method doesn't work correctly.
Does anyone know this problem ?
In advance, thanks a lot.
Best regards,
Farid.
Here is the code of the viewer:
import javax.swing.*;
import javax.swing.border.*;
import java.awt.*;
import java.awt.event.*;
import java.io.*;
import java.lang.*;
public class ViewerQCM extends JPanel {
     private JPanel panelSouth;
     private JLabel titreLabel;
     private JButton genererQCMButton;
     private JEditorPane editorPane;
     private JScrollPane scrollPane;
     public ViewerQCM() {
          JFrame frame = new JFrame("G�n�rateur de QCM");
          setLayout(new BorderLayout());
          panelSouth = new JPanel();
          panelSouth.setLayout(new FlowLayout());
titreLabel = new JLabel("G�n�rateur de QCM", SwingConstants.CENTER);
          editorPane = new JEditorPane();
          editorPane.setContentType("text/plain");
editorPane.setText("Cliquer sur le bouton \" G�n�rer QCM \" ");
          editorPane.setEditable(false);
          genererQCMButton = new JButton("G�n�rer QCM");
          genererQCMButton.addActionListener(new ActionListener() {
               public void actionPerformed(ActionEvent e) {
          GenerateurDeQCM.getInstance().init();
          GenerateurDeQCM.getInstance().generateQuestionnaire();
                    try {
editorPane.setPage("file:" + AccesBase.getString("generateur.QCM"));
                    catch (IOException ex) {
                         ex.printStackTrace();
LogFile.getInstance().write("Exception *** IOException caught in constructor ViewerQCM() ***");
               LogFile.getInstance().write(ex.getMessage());
               LogFile.getInstance().flush();
          scrollPane = new JScrollPane(editorPane);
          add(titreLabel, BorderLayout.NORTH);
          add(scrollPane, BorderLayout.CENTER);
          panelSouth.add(genererQCMButton);
          add(panelSouth, BorderLayout.SOUTH);
frame.addWindowListener(new WindowAdapter() {
public void windowClosing(WindowEvent e) {
System.exit(0);
frame.getContentPane().add(this);
frame.pack();
frame.setSize(500,600);
frame.setVisible(true);
     public static void main(String args[]) {
          new ViewerQCM();
}

hi,
there is some problem with JedtorPane when you update the page. Image or not updated all the time because the buffer keep the old image and does not update it. The problem is that class got to much protected field so you cannot change nothing. It is a bug since Two years and no body as correct it.
