------------------------------------------

Davide,

Thanks for info first off. We have tried 5.6.0 snapshot from sept 13 and the bug still occurs, Only version this works with is 5.3.x We have many rules and I'm sure its not just one rule which will encounter this bug. I will investigate further into your problem description regarding beta constraints, is there any further information you can provide which would aid us in figuring out culprit rule so we can re-write them?

Also the mvel constraint evaluation you refer to, I want to confirm this has nothing to do with switching our selected dialect ? (which is java by default) but condition evaluations use dot notation (mvel) syntax.

Let me know what the new ticket reference number once its created.

> Experienced ClassCastException mixing BetaMemory and AlphaMemory. There is debate in the mailing list/forum. The problem seems to be related to dymanic updates of knowledgebase.
> Saddly there is no deterministic way how to reproduce the issue, but that should not prevent tracking it here.

> java.lang.ClassCastException: org.drools.reteoo.BetaMemory cannot be cast to org.drools.reteoo.AlphaNode$AlphaMemory
