Hi Francois,
yes, that's a non-request thread.
IExceptionMapper isn't a general exception handler, it is a mapper from
exceptions to request handlers.
Using it here does not make sense.
Have fun

Yes, I mean a non-web-request thread, i.e. when the session expires as you've
written.

Hi,
actually #sessionUnbound() is called *on* the application instance, so
the ExceptionMapper is available.
oh, right. silly me!
But ExceptionMapper maps an exception to a requestHandler, this doesn't
make sense for an exception happening on a worker thread.
you meant on *non*-worker thread ?
Francois, please give us the stack trace.
Hope this helps

Hi Francois,
#sessionUnbound() is called in two contexts:
1) the user clicked the Logout button - in this case the call is executed
in http worker thread where there is a ThreadContext, i.e.
Application.get(), Session.get() and RequestCycle.get() would work
here, I think, Wicket should use the ExceptionMapper
2) when the user session has timed out - in this case the web container
(Tomcat/Jetty) will execute this method in non-worker thread and
Application.get() would be null, so we cannot get a reference to the
ExceptionMapper

Hi,
Any RuntimeException thrown in Application # newSession(Request request,
Response response) is handled by the DefaultExceptionMapper #
mapUnexpectedExceptions(Exception e, final Application application)
but
Any RuntimeException thrown in Application # sessionUnbound(String
sessionid) is not handled
Is that normal ?
