JTextField does not redraw properly

Question

Hi,
I have a JPanel that displays some buttons amongst some textfields and labels. One of my buttons is labeled Add Customer. When the user clicks on Add Customer he is presented with a number of JTextFields and JLabels which are all displayed fine.
However, when the user clicks on Cancel or closes the InternalFrame in which the JTextFields and JLabels are displayed and then clicks on Add Customer again, then the JTextFields are not redrawn properly. I image of this behavior can be seen at

As soon as I start to type text into the textfield then the whole textfield redraws itself as it should, but when it looses focus then the textfield becomes invisible once again.
     // Some textfields
     private     JTextField textField_customerEditCompanyName = new JTextField(10);
     private     JTextField textField_customerEditContactName = new JTextField(10);
      * 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_addCustomer = new JButton("Add Customer");
          button_addCustomer.addActionListener(new ActionListener() {
               public void actionPerformed (ActionEvent actionEvent) {
                    // Add a new customer
                    addCustomerListener();
          panel_quoteRequestDetailsButtons.add(button_addCustomer);
          return panel_quoteRequestDetailsButtons;
      * Display a new internal frame when the user wants to add a new customer
     public void addCustomerListener() {
          // Master panel for the add customer details
          JPanel panel_addCustomerMaster = new JPanel();
          // Add the customer details panel to the master panel     
          panel_addCustomerMaster.add(customerDetailsPanel());
          // Ensure that all the textfields are blank
          resetCustomerDetailsPanelTextFields();
          // Add the buttons panel to the master panel          
          panel_addCustomerMaster.add(addCustomerButtons());
          // Add the master panel to the internal frame
          internalFrame_addCustomer.add(panel_addCustomerMaster);
          // Add the internal frame to the desktop pane
          JupiterMainGUI.desktopPane.add(internalFrame_addCustomer);
          // Set the size of the internal frame
          internalFrame_addCustomer.setSize(500,420);
          // Set other properties of the internal frame
          internalFrame_addCustomer.setClosable(true);
          internalFrame_addCustomer.setIconifiable(false);
          internalFrame_addCustomer.setMaximizable(false);
          // Set the location of the internal frame to the upper left corner
          // of the current container
          internalFrame_addCustomer.setLocation(0,0);
          // Set the internal frame resizable
          internalFrame_addCustomer.setResizable(false);
          // Show the internal frame
          internalFrame_addCustomer.setVisible(true);
      * Panel that displays the textfields and labels when the user clicks on
      * add or view customer details
     public JPanel customerDetailsPanel() {
          // Create master container for this panel
          JPanel panel_customerDetailsMaster = new JPanel();
          // Create the container that will hold all the textfields/labels for
          // the creation of a new customer          
          JPanel panel_customerDetails = new JPanel(new SpringLayout());
          // Add the details panel to the master panel
          panel_customerDetailsMaster.add(panel_customerDetails);
          // Set the border for the panel
          panel_customerDetails.setBorder(BorderFactory.createTitledBorder("Customer Details"));
          // Create textfields/labels, add them to the internalFrame
          JLabel label_customerCompanyName = new JLabel("Company Name : ");
          JLabel label_customerContactName = new JLabel("Contact Name : ");
          panel_customerDetails.add(label_customerCompanyName);
          panel_customerDetails.add(textField_customerEditCompanyName);
          panel_customerDetails.add(label_customerContactName);
          panel_customerDetails.add(textField_customerEditContactName);
          //Lay out the panel.
          SpringUtilities.makeCompactGrid(panel_customerDetails,
                                2, 2, //rows, cols
                                5, 5,        //initX, initY
                                5, 5);       //xPad, yPad
          return panel_customerDetailsMaster;
      * Panel holding the buttons when the user clicks on add customer
     public JPanel addCustomerButtons() {
          // Container for the buttons
          JPanel panel_addCustomerButtons = new JPanel();
          // Create the buttons for the panel
          JButton button_customerOk = new JButton("Ok");
          JButton button_customerCancel = new JButton("Cancel");
          button_customerOk.addActionListener(new ActionListener() {
               public void actionPerformed (ActionEvent actionEvent) {
          // Closing the internal frame. When i re-open this internal frame again
              // the labels are re-drawn properly but not the textfields.
          button_customerCancel.addActionListener(new ActionListener() {
               public void actionPerformed (ActionEvent actionEvent) {
                    try {
                         // close and remove the internal frame from the desktop pane     
                         internalFrame_addCustomer.setClosed(true);
                    } catch (PropertyVetoException exception) {
                    JupiterMainGUI.desktopPane.remove(internalFrame_addCustomer);
          panel_addCustomerButtons.add(button_customerOk);
          panel_addCustomerButtons.add(button_customerCancel);          
          return panel_addCustomerButtons;
     }So far I have a solution, and that is to use the GTK look and feel, but it is not really an option. Another way that I have managed to get the textfields to display properly is to create them in the same method, where I create the labels. Again, this is not really an option as i need to access the textfields outside the method scope.
Any help would be greatly appreciated

Answer 1

I added the following :
     * Panel that displays the textfields and labels when the user clicks on
     * add or view customer details
     public JPanel customerDetailsPanel() {
          // Create master container for this panel
          JPanel panel_customerDetailsMaster = new JPanel();
          // Create the container that will hold all the textfields/labels for
          // the creation of a new customer          
          JPanel panel_customerDetails = new JPanel(new SpringLayout());
          // Add the details panel to the master panel
          panel_customerDetailsMaster.add(panel_customerDetails);
          // Set the border for the panel
          panel_customerDetails.setBorder(BorderFactory.createTitledBorder("Customer Details"));
          // Create textfields/labels, add them to the internalFrame
          JLabel label_customerCompanyName = new JLabel("Company Name : ");
          JLabel label_customerContactName = new JLabel("Contact Name : ");
          panel_customerDetails.add(label_customerCompanyName);
          panel_customerDetails.add(textField_customerEditCompanyName);
          panel_customerDetails.add(label_customerContactName);
          panel_customerDetails.add(textField_customerEditContactName);
// Added this line , but doesn't seem to make a difference. also called revalidate() on the
// internalFrame in which this panel is displayed but no luck either. Called revalidate()
// on panel_customerDetailsMaster but nothing :(
          panel_customerDetails.revalidate();
          //Lay out the panel.
          SpringUtilities.makeCompactGrid(panel_customerDetails,
2, 2, //rows, cols
5, 5, //initX, initY
5, 5); //xPad, yPad
          return panel_customerDetailsMaster;
Thanks for the response thou, much appreciated
