I think you'll have to implement an action (extending Action or AbstractAction, not ActionListener) that implements "org.openide.util.ContextAwareAction". Its business method is expected to create a proxy action for the context passed to it. This context is the current user selection of nodes, or the content of these nodes. I guess you'd have to find various methods to extract your URI from this lookup and pass it to the proxy action created. For example look-up a Project and, if present, extract an URI. If no URI at all can be extracted, nevertheless return an action, but its state should be disabled. Hope it helps, Boris
