Remember that this is intermittent, so I figure it should either work or
not. We are working to remove other ingredients to see if it is
environmental.

I'm not certain how WebSphere implements persistent
sessions.
Some application servers (I believe including JBoss),
just periodically serialize the entire HttpSession for
replication purposes. This is really how replication
should work, in my opinion.
Others, such as WebLogic, hook HttpSession.setAttribute
(), so that data replication only occurs when an
attribute is set or changed. This is less intuitive,
and more suited to session attributes that are simple
and immutable.
Tapestry only uses a single HttpSession attribute, but
its value is extremely complex and mutable.
Hm. Puzzling. I just looked at the code and its no
longer conditional, Tapestry will execute
HttpSession.setAttribute() at the end of each request
cycle.
Perhaps your subclass of AbstractEngine is not returning
the correct value from isStateful()?
