Thanks for your reply. The problem I am trying to solve is - somehow
enhance the MyFaces lifecycle with a feature to skip the browser during
rendering (so user is never actually sent the HttpResponse containing the
rendered jsp) that's why have I have 'doNOtRender' and instead immediately
trigger an HttpServletRequest in the lifecycle to simulate the user
clicking a button in the jsp and submit to faces servlet .
I am trying to actually doing this in ServletExternalContextImpl.dispatch()
method.
Thanks
Asha
