Saving dirty data in Applet shutdown() lifecycle method issue

Hello,

I have written code for a Java Applet shutdown() lifecycle method.
The issue I am having is that when I click a powerbar button on a top level frame, I lose my dirty data.
For some reason, the following code snipped is not doing its job.
What I want is to allow enough time for dirty data to be save before killing my applet and changing my display.

Here is the code snippet:

    public void shutdown() {
        if (configurationManager.isModifedConfigurations()) {
              int selection = 999;
              
            // Discard changes ?
            selection = JOptionPane.showConfirmDialog(null, messages.getString("ConfigPowerbarChangeConfirmMsg"),
                    messages.getString("ConfigPowerbarChangeConfirmMsgTitle"),
                    JOptionPane.YES_NO_OPTION);
           
            if (selection == JOptionPane.NO_OPTION) { //Discard Changes
                configurationManager.setModifedConfigurations(false);

                super.shutdown();
                removeBindings();
                stopCurrentApplet();
            } else if (selection == JOptionPane.YES_OPTION) { //Force Save changes
                  System.out.println("Catch ApplicationEvent !!! Force Save of Mutable Table fields.");

                try {
                              SwingUtilities.invokeAndWait(new Runnable() {
                                  public void run() {
                                        toolbarController = new ToolbarController(ToolbarModelFactory.getSystemwideToolbarModel());
                                          ApplicationEvent evt = new ApplicationEvent(ToolbarController.SAVE, toolbarController);
                                          toolbarController.handleApplicationEvent(evt);
                                       }
                              });
                        } catch (InterruptedException e) {
                              e.printStackTrace();
                        } catch (InvocationTargetException e) {
                              e.printStackTrace();
                        }
                 }
        }
    }


Suggestions ?
