I am using a MenuBar navigator in mu application. The data for the menu comes from an XML file. The menu contains top-level nodes as well as sub-nodes. All the sub-nodes work as designed. I can click on the node and the action called runs. However, none of the top-level nodes that do not have sub-nodes do anything when clicked. I need these node to also be clickable and run actions just as the sub-nodes do. Is there a properties within the MenuBar control that I need to set?
