Adding a new Tab to an existing JTabbedPane not working

Question

Hello all,
I am trying to add & display a new tab to an existing JTabbedPane when the user
clicks on a button. For some reason the new tab, being added is not being displayed, and I don't know why. I have called invalidate(), validate() on the parent containers but haven't had any luck. I have also played around with SwingUtilities.invokeLater() and the Event thread, but have been unsuccessfull.
Any help would be greatly appreciated.
      * This class is the parent that holds the internalFrame which is the
      * main parent for all subsequent containers
     public class QuoteRequestGUI implements QuoteRequestGUI_IF {
          protected JInternalFrame internalFrame_newQuoteRequest = new JInternalFrame("Quote Request");
          protected JTabbedPane tabbedPane = new JTabbedPane();
           * Create a new internal frame to which all the components of a new
           * QR will be added
          public JInternalFrame createNewQuoteRequestFrame() {
               // Add a tabbed pane to the internal frame
               internalFrame_newQuoteRequest.add(createQuoteRequestTabbedPane());
               // .... Set various internalFrame properties
               return internalFrame_newQuoteRequest;
          public JTabbedPane createQuoteRequestTabbedPane() {
               // Create a new quote request details instance
               QuoteRequestDetailsGUI_IF quoteRequestDetailsGUI =
                    new QuoteRequestDetailsGUI(quoteRequestStatusPassed);
               // Create a new tab that will host all details of the quote request     
               tabbedPane.addTab("Quote Request Details",
                         quoteRequestDetailsGUI.createQuoteRequestDetailsPanel());
               return tabbedPane;
     public class QuoteRequestDetailsGUI extends QuoteRequestGUI implements QuoteRequestDetailsGUI_IF {
          private ProductDetailsGUI_IF productDetailsGUI = new ProductDetailsGUI();
           * Panel that will act as a container for both quote request and buyer
           * details
          public JPanel createQuoteRequestDetailsPanel() {
               // Panel that will contain quoteRequest, buyer and buttons
               JPanel panel_quoteRequestDetails = new JPanel();
               // Create an intermediate panel so that components can be layed out properly
               JPanel panel_quoteRequestIntermediatePanel = new JPanel();
               // Set layout manager for panel
               panel_quoteRequestIntermediatePanel.setLayout(
                    new BoxLayout(panel_quoteRequestIntermediatePanel,BoxLayout.PAGE_AXIS));
               // Add the buttons
               panel_quoteRequestIntermediatePanel.add(createQuoteRequestDetailsButtons());
               // Add the intermediate panel to the main panel
               panel_quoteRequestDetails.add(panel_quoteRequestIntermediatePanel);
               return panel_quoteRequestDetails;
           * Panel that will hold all the buttons for the quote request details tabbed panel
          public JPanel createQuoteRequestDetailsButtons() {
               // Panel to act as a container for the buttons
               JPanel panel_quoteRequestDetailsButtons = new JPanel();
               // Create, register action listeners and add buttons to the panel
               JButton button_saveTabbedPane = new JButton("Save");
               button_saveTabbedPane.addActionListener(new ActionListener() {
                    public void actionPerformed (ActionEvent actionEvent) {
                           saveTabbedPaneListener();
               panel_quoteRequestDetailsButtons.add(button_saveTabbedPane);
               return panel_quoteRequestDetailsButtons;
           * Display the save (product details) tabbed pane
           * @todo - Implement the save tabbed pane selected method
          public void saveTabbedPaneListener() {
                    log.info("tab count before added : " + tabbedPane.getTabCount());
                    // The product details of a particular quote request
                    tabbedPane.addTab("Product Details",
                              productDetailsGUI.createProductDetailsPanel());
                    log.info("tab count after added : " + tabbedPane.getTabCount());
                    tabbedPane.invalidate();
                    tabbedPane.validate();
                    internalFrame_newQuoteRequest.revalidate();
     public class ProductDetailsGUI implements ProductDetailsGUI_IF {
           * Panel that will act as a container for both the product details (incl
           * table) and the buttons
          public JPanel createProductDetailsPanel() {
               // Main product details panel
               JPanel panel_productDetails = new JPanel();
               // Add the scroll pane to the panel
               panel_productDetails.add(new JButton("ok"));
               // Add the buttons to the panel
               // Add the scroll pane to the panel
               panel_productDetails.add(new JButton("cancel"));
               return panel_productDetails;
     }

MS,
Try copying one existing TAB and use that, this happens only when there is improper xml content. You can open the xml in the browser/visual studio for better clarity and then try making the changes. Doing IIS Reset will be required but in the meanwhile you
can put the original RCDC which will work till the time you make any change in new TAB.
