Hum... This is what I see for line 428
(BridgeImpl.doFacesRequest(BridgeImpl.java:428):
if (request.getPortletSession().getAttribute(key) == null)
As the request object has already been dereferenced before this line,
the only way, that I can see, that this can throw a NullPointerException
is if getPortletSession is returning null -- however by (Portlet) spec
this isn't expected as this call should automatically create a session
if one doesn't exist. And given that you seem to be running on a version
of Pluto (which in other environments behaves correctly) its a mystery.
Sounds like this one will take a little debugging. Can you either grab
the sources for the version of pluto (and the bridge) and debug into
this and send more information? Or can you package up the entire
environment (portal/appserver, etc) as a zip and send it to me? If you
do this later I need to know the specific version of pluto being used so
I can pull/debug with the appropriate sources.
