[rules-users] java.lang.ClassCastException: org.drools.reteoo.BetaMemory cannot be cast to org.drools.reteoo.AlphaNode$AlphaMemory

[AlesD]

I understand that, but as far as I can say, it is not in the rules or facts.
I have restarted our solution, used same rules and fed them with same facts.
This time everything went without errors.

Could you please give us hint what BetaMemory and AlphaNode and under which
circumstances the one is case to another. Right now I can provide stack
trace and quite detailed log (created by custom Agenda/WorkingMemory/Process
listeners) if you wish. I doubt however that it will help.

Ales
