Re: [wsrp] Action redirects to self

[Michael Freedman <michael.freedman@oracle.com>]

The only realistic use would be to redirect using a render url.  Yes, 
its virtually identical to what the consumer is doing anyway but is 
[potentially] interesting when the producer environment isn't cognizant 
that the action/render phase occurs in 2 requests.  JSF is an example of 
such an environment.  In JSF the action and render phase typically occur 
in a single request lifecycle.  The developer however does have an 
option via a declaration in the navigation rule [directs where to flow 
from an action to a render] that this navigation happen across a 
redirect.  In such a circumstance JSF generates a redirect at the end of 
the action vs doing an internal navigation/render.  If JSF is being used 
to implement the portlet we need to reconcile/finesse the JSF behaviour 
[which relies on a standard implementation] with our own.
