[RE: Apache Con US 2005 - Myfaces Portlet support]

[su...@tatainfotech.com]

Yeah, the session scoped data works fine with Myfaces portlets.
I changed the scope of managed beans from request to session in the
faces-config  and it worked fine.

But if the scope of managed beans is request, then it doesnt work.

I converted simple.war(taken from myfaces-1.1.1-examples) into a portlet
and specified the default-view as /sample1.jsp in portlet.xml

The page came nicely on jetspeed portal but it was losing out the request
scoped data. Then I modified the scope of managed bean used in this jsp to
session and it worked fine after that.

The main page of simple.war is home.jsp which contains many <h:output>
links and this page gives exceptions : portletexception.

What do you think about the request scope stuff? Am I missing out something?

Do you want me to raise it as a issue?

Thanks,
Sunil

scanned the link you posted and I don't see a clear complaint.  I would
need more to go on than "It doesn't work".
