RE: WebSession shutdown
Thanks Eelco, but... The trouble is that the lifecycle of a Wicket WebSession object is not the same as the HTTPSession. When a session is temporary only, you never get a valueUnbound() callback. I'll have to move the resource manager initialization into the valueBound() method; inconvenient but not a problem per se. My second objection is that this works, as you said, with the default implmentation of ISessionStore. I would introduce a dependency on the exact implementation of ISessionStore used, not any published API. That somehow fills me with sombre premonitions ;-) I still think it would be nice if org.apache.wicket.Session had a proper lifecycle (à la WebApplication.onDestroy()). Should I file a feature request or start a conversation on the dev list? Thomas -Original Message- From: Eelco Hillenius [mailto:[EMAIL PROTECTED] Sent: Donnerstag, 20.

I'll have to move the resource manager initialization into the valueBound() method; inconvenient but not a problem per se. Ah yeah, but temporary sessions are volatile anyway. You could implement a custom request cycle that in onEndRequest checks whether the session is temporary, and if so, let it call the cleanup method.

Should I file a feature request or start a conversation on the dev list? Sure, you can start a discussion on the dev list, and filing a JIRA issue makes that it will be a more persistent discussion topic. Having it here is fine too though. I'm not sure whether depending on the Session object being put in the HttpSession is bad for you though. If you are not using that, it probably means you're working with a custom session store in which case you could just make sure your cleanup callback gets called by that, right?

WebSession shutdown
Hi folks, In our WebSession subclass we manage some resources which need to be cleaned up when the session goes away (because of timeout, etc). Is there a recommended way to call a shutdown() method on our session class? I have seen WebApplication.sessionDestroyed(String), but I'm not sure how to get the wicket session from there (since we don't necessarily have an active request at that time). Of course, I could implement my own session store or something like that, but that approach seems to be a bit hackish.
