Re: [Wicket-user] Pagemap null is locked
Everyone, This was a secondary effect caused by a Model that could not be successfully serialized. In the model, one of the members held a non-serializable object. I set the member to null in the onDetach() method, but apparently onDetach() was not being called. I have since changed the member so that it is declared as transient, since all I was doing in onDetach() is setting it to null. I am investigating why onDetach() was not called, but have not yet come up with an answer. Thanks, On Tue, 2006-09-12 at 14:29 -0500, Philip A.

Re: [Wicket-user] Pagemap null is locked
Did you have any luck with this yet tracking it down?Because i am very curious how this can happen because in the detach of the request i am clearing all things of the current threadin that map. So why something hangs is very strange. If you could debug or change the src a bit of wicket (by placing some output statements in at wicket.Session.getPage(Session.java:482)where you print the thread and the pagemap that is just lockedand then also print out on the release.I am then very curious why it doesn't get to the detach.. johanOn 9/12/06, Philip A.

Re: [Wicket-user] Pagemap null is locked
Nasty. Maybe you can set a breakpoint in Session.requestDetached in getPage (line 486). And for us something reproducible runnable would help :) Eelco On 9/12/06, Philip A.
