         * to trigger the events-based features of the portlet, but atm I don't
         * see a way around it, since..
         *
         *   - (1) You can only start an event chain in the Action phase;  and
         *   - (2) You can only return JSON in a Resource phase;  and
         *   - (3) An un-redirected Action phase leads to a Render phase, not a
         *     Resource phase :(
         *
         * It would be awesome either (first choice) to do Action > Event > Resource,
         * or Action > sendRedirect() followed by a Resource request.
         *
         * As it stands, this implementation will trigger a complete render on
         * the portal needlessly.
