Hi Elias, Have you discussed JBCACHE-880 on the forums yet? I don't see a link to a forum thread on the task. I'm not too excited by the implementation here, putting 'special' values in a node's hashmap is always ugly and although we do it with the UNITIALIZED marker, I'm not a fan of this. We should discuss this a bit further on the forums, see if there is a better solution. Also, I'd like to understand the use case a bit better as to why such a mechanism is useful in a 'generic' implementation (I can see this as a great custom policy, though) Cheers, -- Manik Surtani Lead, JBoss Cache JBoss, a division of Red Hat Email: manik(a)jboss.org Telephone: +44 7786 702 706 MSN: manik(a)surtani.org Yahoo/AIM/Skype: maniksurtani
