Re: [starter-dev] Return of the Dreaded View Expiration!

[Reza Rahman <reza_rahman@xxxxxxxx>]

Do you mind kindly making a PR with the approach you think is best overall? I'll test it out and monitor that it works. I appreciate it!

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.

Hi,

 

I had to remove STATE_SAVING_METHOD=client because I could not get it to work

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
