What listener is triggered when an already rendered card panel comes back into view? I have a card panel comprised of a menu list. When touched, each menu calls an AJAX page with buttons that appear in a toolbar. One of those is a back button that re-displays the menu-list panel. I've tried using a render event, but that doesn't seem to work. It may be my code, but I want to know if render is the correc listener, or is there another?
