Re: Problem with Pluto Portlets and the Sun JSF Portlets

I had directed Eric over here from the uPortal lists.

It appears that the JSF-Portlet library adds a response wrapper before 
calling the request dispatcher. Does anyone here know if that is allowed 
under JSR-168? There is no mention I can find in the spec or errata. I 
do know in 286 explicit wrapper classes were added that mimic the 
servlet API wrapper classes but that is all I've been able to find. 
Should this be viewed as a Pluto bug or a JSF-Portlet bug?
