Currently, the ListViewCallback implementations MUST return the exact url to be redirected to from the perform method. For example, the UpdatePermissionCallback returns "/AssignedGroups.do". This is mapped in the struts-config.xml. In essence we should have better integration with Struts from our PaginationServlet.
Ok I must've been on crack or something when I wrote this bug. But the AssignedGroups.do is the actual mapping in the struts-config.xml there's nothing else to map. Closing this bug.
