cannot destroy component exception

[henrik.lindberg]

I keep getting exceptions when a session times out. The trace is below:
What could be causing this? What should I do?

I also get exceptions like this when using some ajax button on the page after the page has timed out.

You're not the only one. I get the same exceptions. Seam appears to have quite a few flaws like this. I'm quickly losing confidence in it.

[gavin.king]

You need to set your SFSB timeout longer than your HTTP session timeout. This is in the FAQ, and we have already added it to the reference documentation.

I'm not sure how a simply config setting that is described in the FAQ, and has been discussed in several forum threads could lead you to lose confidence in a project, but that's just me, I suppose.

[henrik.lindberg]

Thanks Gavin, I have not lost confidence + the support and helpfulness of everyone here in the forums is just great !

Hope to be able to contribute back when I have learned more.

[henrik.lindberg]

Found this issue logged regarding this, but I am having trouble finding anything else regarding this...
http://jira.jboss.org/jira/browse/EJBTHREE-788

Which FAQ is this?

[henrik.lindberg]

found this - but it does not help with my problem afaics:
http://wiki.jboss.org/wiki/Wiki.jsp?page=SeamProblemsFAQ

[gavin.king]

http://wiki.jboss.org/wiki/Wiki.jsp?page=JbossTimeoutSettingForSeam

I'm not sure why this was not linked from the main FAQ page, but google found it quick enough.

[henrik.lindberg]

Thanks, problem is now cured.

Was not easy to find that FAQ until you provided the URL. I actually did google for "HTTP Session Timeout SFSB JBoss" and combinations thereof, but the page with the answer was not among the first 3-4 pages anyway...

It just seems totally lame that you have to make such a configuration change to avoid the exception and it reduces application flexibility if the session timeout needs to be changed in future as each and every session bean would need to be changed. A better solution needs to be found.

[kukeltje]

feel free....imo seams solves so many other issues, that this small issue is of so little importance to us.....

[henrik.lindberg]

waynebagguley, you don't have to change every bean - the fix that is in the FAQ shows how to do it.

Problem is now gone.

[waynebagguley]

Doing the fix at the container level isn't a valid solution.

[gavin.king]

Then complain to the EJB3 team, as I have already done. I don't know exactly why you're blaming Seam for this, since Seam has absolutely nothing to do with HTTP session and SFSB timeouts.
