I wanted to thank you again for your kind help. I am going to
keep an eye on things the rest of the week, but it appears the
view expirations are entirely gone now.

OK, great. Let me test it and get it deployed. I'll
monitor for any more issues and also try to ensure sticky

Yeah. The issue boils down to that
the view scoped bean referenced in the
p:selectOneRadio is created for the first time
when the response is already committed. And view
scoped beans need to be saved in the session.
But when the response is already committed the
cookie associated with the session cannot be
set.
Another solution is to add a f:viewAction
referencing some bean init method and use that
instead of postconstruct. This is guaranteed
invoked before render response.
Yet another solution is to create a servlet
filter which does an
explicit request.getSession() call.
You got it.

To some extent, the symptoms at least
appear simple. We are now getting copious
amounts of views expired (example stack
trace attached). I had seen this in prior
releases with JBoss EAP 7.4 (and the
corresponding WildFly version). What I did
is to set STATE_SAVING_METHOD=client. It
worked well and saw no more views expiring
in the logs.
Then we upgraded to JBoss EAP 8 and the
corresponding WildFly versions. Now with
STATE_SAVING_METHOD=client, I get this
strange session state saving issue
(example stack trace also attached). So we
are stuck with views expiring again.
Let me know if I can share anything else.
Let me see if there is anything I can do
to ensure sticky sessions. Because this is
deployed to an Azure PaaS, I have a very
limited amount of control.

Would be helpful if you elaborate this
in detail. It might be a clue. One of
pre-requirements for that in a cluster
environment is that the
jsf/ClientSideSecretKey
env param is set (usually in web.xml).
This has been renamed to faces/ClientSideSecretKey.
So if the cluster doesn't use sticky
sessions then ViewExpiredException
will occur.
Hey Reza,
Can you provide some more
details (perhaps point me to
logs or explain any scenarios)?
We're still partners with
PrimeTek and I still work with
Bauke Scholtz (cc'd), so we can
figure it out.

Hi
Kito/others,
I have been monitoring the
release for stability and
unfortunately we
have a problem that needs to be
solved. I had to remove
STATE_SAVING_METHOD=client
because I could not get it to
work with the
latest PrimeFaces/Jakarta EE
10/JBoss EAP 8. Now we have the
infamous
JSF problem of views expiring
left and right again of course.
I will
keep trying this weekend, but
can you possibly help me look at
this and
solve it? You still have some
contacts with the PrimeFaces
folks, right?
Could they help? This appears to
be mainly a PrimeFaces problem.
Thanks,
Reza
