JPanel methods arn't being overriden in my subclass.

Question

Basically I have a JPanel class which I want to use as a template (super class) for other GUI Items. These other GUI items extend off this class, but also have the ability of altering the appiernece of the panel by overiding some functions. As far as I can tell, they arn't overiding.
Here's an example of what I'm trying to do.
package lastGUI;
import javax.swing.JPanel;
import javax.swing.JSeparator;
import com.jgoodies.forms.builder.PanelBuilder;
import com.jgoodies.forms.layout.CellConstraints;
import com.jgoodies.forms.layout.FormLayout;
* A template Panel
* @author Yves Samuel Wheeler
public class Template extends JPanel {
     private static final long serialVersionUID = 1L;
     private JSeparator Separator;
     public Template() {
          super();
          initGUI();
     private void initGUI() {
          instantiateComponents();
          add(buildMainPanel());
     private void instantiateComponents() {
          Separator = new JSeparator(JSeparator.VERTICAL);
     private JPanel buildMainPanel() {
          FormLayout formLayout = new FormLayout(
                    "pref:grow, 15dlu, pref, 15dlu, pref:grow", // columns
                    "15dlu, pref:grow, 15dlu"); // rows
          PanelBuilder panelBuilder = new PanelBuilder(formLayout);
          CellConstraints cellConstraints = new CellConstraints();
          panelBuilder.add(buildLeftPanel(), new CellConstraints(
                    "1, 1, 1, 1, fill, fill"));
          panelBuilder.add(Separator, cellConstraints.xywh(3, 1, 1, 3));
          panelBuilder.add(buildRightPanel(), new CellConstraints(
                    "5, 1, 1, 1, fill, fill"));
          return panelBuilder.getPanel();
     protected JPanel buildRightPanel() {
          FormLayout formLayout = new FormLayout("pref", // columns
                    "pref"); // rows
          PanelBuilder panelBuilder = new PanelBuilder(formLayout);
          CellConstraints cellConstraints = new CellConstraints();
          panelBuilder.addLabel("Right", cellConstraints.xy(1, 1));
          return panelBuilder.getPanel();
     protected JPanel buildLeftPanel() {
          FormLayout formLayout = new FormLayout("pref", // columns
                    "pref"); // rows
          PanelBuilder panelBuilder = new PanelBuilder(formLayout);
          CellConstraints cellConstraints = new CellConstraints();
          panelBuilder.addLabel("Left", cellConstraints.xy(1, 1));
          return panelBuilder.getPanel();
package lastGUI;
import javax.swing.JPanel;
import com.jgoodies.forms.builder.PanelBuilder;
import com.jgoodies.forms.layout.CellConstraints;
import com.jgoodies.forms.layout.FormLayout;
public class MyPanel extends Template {
     public MyPanel() {
          super();
          // TODO Auto-generated constructor stub
     protected JPanel buildRightPanel() {
          FormLayout formLayout = new FormLayout("pref", // columns
                    "pref"); // rows
          PanelBuilder panelBuilder = new PanelBuilder(formLayout);
          CellConstraints cellConstraints = new CellConstraints();
          panelBuilder.addLabel("This Panel has also been overiden!",
                    cellConstraints.xy(1, 1));
          return panelBuilder.getPanel();
     protected JPanel buildLeftPanel() {
          FormLayout formLayout = new FormLayout("pref", // columns
                    "pref"); // rows
          PanelBuilder panelBuilder = new PanelBuilder(formLayout);
          CellConstraints cellConstraints = new CellConstraints();
          panelBuilder.addLabel("This Panel has been overiden!", cellConstraints
                    .xy(1, 1));
          return panelBuilder.getPanel();
}Any help would be apprieciated.
Thanks :)

The MyPanel methods are overriding the parent methods alright.
If you try:
public static void main(String[] args)
     JFrame frame = new JFrame();
     frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
     frame.add(new MyPanel());
     frame.pack();
     frame.setVisible(true);
}the overriden panels shows up.
Can you post the snippet where you call the MyPanel class?
