that will work for the PortalRequestContext, but not the
PortletRequestContext (since that uses the portlet responses instead of
the http ones).

I have a patch for it that will make the PortalRequestContext work this
way, and then makes the UIPortlet use the parameter map from the
PortalRequestContext which is used by the pc to set the
PortletRequestContext.
