Why all JMenuItem's of JPopupMenu perform the same action?

Question

Why all JMenuItem's of JPopupMenu perform the same action?
I trying to do something similar to what there is in JBuilder where you right click a method or a class - you get a popUpMenu and if you choose the
"Browse Symbol" JBuilder browses to that method/class.
I'm trying to do the same and to browse to some class of mine (not a java class). But there's a problem.
This is my code : -
OMClass desiredClass = event.getNavigationClass();
if(desiredClass instanceof OMComplexClass) {
Set classSet = desiredClass.getSimpleClasses();
JPopupMenu menu = new JPopupMenu();
JMenuItem menuItem = null;
menu.add("Browse to :");
menu.addSeparator();
Iterator it = classSet.iterator();
for(; it.hasNext(); ) {
OMConcept concept = (OMConcept)it.next();
menuItem = new JMenuItem(concept.getName());
menuItem.addActionListener(new NavigateToComplexClass(concept));
menu.add(menuItem);
menu.show((JComponent)(event.getMouseEvent().getSource()), getX(), event.getMouseEvent().getY());
ComplexClass is build of SimpleClasses - so if I want to browse to complex class I ask the user by a JPopupMenu what specific SimpleClass he would like to browse to. My ActionListener is a NavigateToComplexClass class - and hewe is the code : -
public class NavigateToComplexClass implements ActionListener, ItemListener {
private static OMClass classToShow = null;
GUI_Location currentLocation = null;
public NavigateToComplexClass(OMConcept desiredClass) {
classToShow = (OMClass)desiredClass;
public void actionPerformed(ActionEvent evt) {
currentLocation = frame.fillGUI_Location();
frame.getProject().getHistoryManager().updateHistory(currentLocation);
if(classToShow == null) {
return;
frame.getClassDisplay().getTabbedPane().setSelectedIndex(1);// 1 - parameeter : Property tab.
frame.getConceptViewPanel().selectConcept((OMConcept)classToShow);
public void itemStateChanged(ItemEvent e) {
The problem is that no matter what JMenuItem I select and press it's navigating to the same simpleClass like if I have a
b
c
no matter what I'll press I'll always goto a (or b or c but always the same)

hi,
for your actionlistener all those items are more or less the same. when browsing to them you have to give them different names or better different actioncommands.
