conditional popup menu in jtree

I want a conditional popup menu in jtree based upon which node i right click upon. Is it possible? I implemented it as follows but if I click on node at depth level 1 first it shows correct popup menu but then after if I right click on node at level 2 I still get the same popup menu as for level 1. And similarly vice versa.

DefaultMutableTreeNode node = (DefaultMutableTreeNode) pmTree.getLastSelectedPathComponent();
    popup = new JPopupMenu();
    popup.setInvoker(pmTree);
    PopupHandler handler = new PopupHandler(pmTree, popup);


    if(node.getLevel() == 1)
    {
        popup.add(getMenuItem("Start a VM", handler));
        popup.add(getMenuItem("Monitor all VMs", handler));

    }

    else if(node.getLevel() == 2)
    {
        popup.add(getMenuItem("Change VM configuration", handler));
        popup.add(getMenuItem("Monitor VM", handler));
        popup.add(getMenuItem("Migrate VM", handler));
        popup.add(getMenuItem("Show VM Configuration", handler));
        popup.add(getMenuItem("Stop VM", handler));
    }

This question appears to be relevant to your situation:

JTree and dropdown options on right clicking nodes

Can you post more of your code?

Its hard to tell without more context but I assume the problem is that the menu is getting built and initialized on the first click but not replaced on the subsequent click.

This should be possible, try printing out node.getLevel() first to ensure that the level is correct before it enters the conditional code. Since you're creating a new JPopupMenu object each time it doesn't seem that you should need to call removeAll() on popup. Is this code called in a Method each time a node is clicked? Also is it possible that the node at level 1 is shadowing input from the node at level 2?
