> The render attribute of AjaxBehavior should evaluated during post-back after 'Invoke Application' and before 'Render Response'. It's easly to add this feature with a own PartialViewContext. But there is no call to processPartial with 'Invoke Application'. The Phase 'Render Response' is too late if you are using c:if to skip components from the component tree. See attached example app and pictures.
