Hi,
is it guaranteed that the SessionStoreListener#beforeDestroy listener is
always called in the context of the session that is destroyed? Can I
access SessionSingletons without the danger of being diposed already?

Regards,
Stefan.

Hi,

yes, it's one of the reasons why we introduced the ISessionStore
abstraction - to allow a 'defined' shutdown process.
ISessionStoreListener#beforeDestroy gets invoked before any attribute is
removed from the store. Furthermore the implementation ensures that
beforeDestoy is executed in the UIThread of the session - so
SessionSingletons should be accessible without any special treatment.

Ciao
Frank

Excellent - I hoped that you would say this :-)
