Hi, I’m having a hard time to get a popup-dialog working in the 3d view:

It should have a text, slider and cancel, ok-button.
But it looks like I mixed something, hard to understand how dialogs work as InternalFrame in the 3d window.
Also I would like to have the slider between the text and the cancel/ok buttons.
Can anyone help me?
Here is my code, it sadly always recives ‘uninitializedValue’ from the buttons:

private void showArmyDialog(int armyNr, int cityNr) {
        final JDesktopPane desktopPane = jmeDesktop.getJDesktop();
        final JInternalFrame modalDialog = new JInternalFrame("Army" + DataModel.vArmies.get(armyNr).get_name());
        String whatDoStr ="";

        if (DataModel.aCities[cityNr].get_party() != (DataModel.vArmies.get(armyNr).get_party())) {
         whatDoStr="Army "+ armyNr+" player("+DataModel.vArmies.get(armyNr).get_party()+") "+DataModel.aGenerals[DataModel.vArmies.get(armyNr).get_general()-1].get_name()+"nattacks: " + DataModel.aCities[cityNr].get_name()+" player("+DataModel.aCities[cityNr].get_party()+")";
          Debug.text(whatDoStr);
       } else {
         whatDoStr="Army "+ armyNr+" player("+DataModel.vArmies.get(armyNr).get_party()+") "+DataModel.aGenerals[DataModel.vArmies.get(armyNr).get_general()-1].get_name()+"nmoves: " + DataModel.aCities[cityNr].get_name()+" player("+DataModel.aCities[cityNr].get_party()+")";
          Debug.text(whatDoStr);
        }

        Object[] options = {"attack","cancel"};

        int n;
        JOptionPane optionPane = new JOptionPane(whatDoStr,JOptionPane.QUESTION_MESSAGE,
        JOptionPane.YES_NO_OPTION, null,     //do not use a custom Icon
        options,  //the titles of buttons
        options[0]);

        modalDialog.getContentPane().add(optionPane);
        jmeDesktop.setModalComponent(modalDialog);
        desktopPane.add(modalDialog, 0);
        modalDialog.setVisible(true);
        modalDialog.setSize(300, 300);//getPreferredSize());
        modalDialog.setLocation((desktopPane.getWidth() - modalDialog.getWidth()) / 2,
                (desktopPane.getHeight() - modalDialog.getHeight()) / 2);

        final JPanel anPanel = new JPanel();

        JButton lbutton = new JButton("<");
        JButton rbutton = new JButton(">");
        lbutton.setSize(lbutton.getPreferredSize());
        /*lbutton.setLocation( (int) ( ( display.getWidth() - lbutton.getWidth() ) / 2
        + display.getWidth() ), display.getHeight() - 40 - lbutton.getHeight() / 2 );
        rbutton.setSize( rbutton.getPreferredSize() );
        rbutton.setLocation( (int) ( ( display.getWidth() - rbutton.getWidth() ) / 2
        + display.getWidth() ), display.getHeight() - 40 - rbutton.getHeight() / 2 );*/
        anPanel.add(lbutton);

        JSlider slider = new JSlider(0, DataModel.vArmies.get(armyNr).get_strength(),DataModel.vArmies.get(armyNr).get_strength());
        //Debug.text(""+DataModel.vArmies.get(armyNr).get_strength());

        //slider.setValue(DataModel.vArmies.get(armyNr).get_strength());
        //slider.setMaximum(DataModel.vArmies.get(armyNr).get_strength());
        anPanel.add(slider);
        anPanel.setDoubleBuffered(false);
        //anPanel.setOpaque( false );

        anPanel.add(rbutton);
        optionPane.add(anPanel);

        optionPane.revalidate();
        jmeDesktop.setFocusOwner(optionPane);

        desktopPane.repaint();

               Object selectedValue = optionPane.getValue();
         System.out.println("Ja gewählt: "+selectedValue);
      if(selectedValue != null && selectedValue instanceof Integer){
        int option = ((Integer)optionPane.getValue()).intValue();
      if ( option == optionPane.YES_OPTION )
        System.out.println("Ja gewählt");
       }

        optionPane.addPropertyChangeListener(JOptionPane.VALUE_PROPERTY, new PropertyChangeListener() {

            public void propertyChange(PropertyChangeEvent evt) {
                modalDialog.setVisible(false);
                jmeDesktop.setModalComponent(null);
                desktopPane.remove(modalDialog);
                popup = false;
            }
        });

    }
