    Default Tooltip HTML format problem

    I am using an HTML formatted tool tip on a JButton.
    All is fine the first time I launch my applet.
    However, if I close the Applet browser window and re-launch, the tool tip is blank.
    This is only for <html> formatted text, non-HTML strings are fine.
    It is not browser specific (same behavior for IE,FF,SF,etc).
    Is this a known problem, or maybe I'm missing something?

    example:
    btn.setToolTipText("<html>does not work after re-launch</html>");
    btn.setToolTipText("works fine after re-launch");

    Hard to understand how a program will work one time and then not another.
    Is there a difference when you load the html page in the browser between the time it works and the time it doesn't work?
    Or is this a case of you moving off the html page with the applet and coming back to it?
    The applet has methods that are called when that happens.

    I'm not doing anything funky. The HTML <APPLET> tags is also quite generic

    Java Code: 
    <APPLET 
   ARCHIVE  = "/java/test/MyApplet.jar" 
   CODE     = "test/MyApplet.class"
   NAME     = "test" 
   HEIGHT   = "100%"
   WIDTH    = "100%"
   MAYSCRIPT >
</APPLET>
    Java Code: 
    package test;

import java.awt.event.*;
import javax.swing.*;

public class MyApplet extends javax.swing.JApplet implements Runnable {

    public static final long serialVersionUID = 1L;           
    
    private final String TT_HTML       = "<html>HTML</html>";
    private final String TT_NON_HTML   = "NonHTML";


    /** Initializes the MyApplet */
    public void init() {
        initComponents();
    }
    
    public void start(){
        updateBtnControl();
    }
    
    public void run() {
    }

    private void updateBtnControl() {
      String tt = btnControl.getToolTipText();

      if ((tt==null) || (tt.equalsIgnoreCase(TT_HTML))) {

        btnControl.setToolTipText(TT_NON_HTML);
      }
      else {
        btnControl.setToolTipText(TT_HTML);
      }
    }

    // <editor-fold defaultstate="collapsed" desc="Generated Code">
    private void initComponents() {

        btnControl = new javax.swing.JButton();

        btnControl.setFocusable(false);
        btnControl.setHorizontalTextPosition(javax.swing.SwingConstants.CENTER);
        btnControl.setVerticalTextPosition(javax.swing.SwingConstants.BOTTOM);
        btnControl.addActionListener(new java.awt.event.ActionListener() {
            public void actionPerformed(java.awt.event.ActionEvent evt) {
                btnControlActionPerformed(evt);
            }
        });
        getContentPane().add(btnControl, java.awt.BorderLayout.CENTER);
    }// </editor-fold>
                    
    private void btnControlActionPerformed(java.awt.event.ActionEvent evt) {                                           
      updateBtnControl();
    }                                          

    // Variables declaration - do not modify
    private javax.swing.JButton btnControl;
    // End of variables declaration
    
}

    What's supposed to happen when the applet is loaded in a browser?
    I get a full screen button with no text.
    Then what?

    Yes, that sounds about right.
    I stripped my Applet down to bare bones for demonstration purposes.
    You are looking at a big button with no text or icon.
    The tool tip toggles every time to click this button (after a mouse over).
    You should notice that the tool tip will toggle between "HTML" and "NonHTML".
    If you kill the browser and relaunch, the "HTML" tool tip goes away.

    I am also creating my window something like;
    javascript:void(window.open(\"/launch.html\",\"1062731320\",\"status=yes,scrollba rs=yes,resizable=yes,menubar=no,toolbar=no,directo ries=no,location=no,width=700,height=500\"))

    Have you added printlns to all the methods and the constructor to see when they are called?

    I get the second TT sometimes as a short dark blue line vs the text.

    When I changed this variable I get the full text:

    private final String TT_HTML = "<html>HTML that is longer than the other one</html>";

    I always get the "short dark blue line vs the text" (:

    So you are able to reproduce the error?

    It is odd that it works for you after increasing TT_HTML variable.

    Yes, that can be the nature of a bug.
