Hi,

When executing my rules for an object, on some objects I get a ClassCastException:

java.lang.ClassCastException: org.drools.reteoo.CollectNode$CollectMemory cannot be cast to org.drools.core.util.ObjectHashMap
at org.drools.reteoo.RightInputAdapterNode.assertLeftTuple(RightInputAdapterNode.java:128)
(full stack-trace: http://pastie.org/877237)

I've looked around in the source around where this happens, and can't figure out how it relates to my rules-file. (http://pastie.org/877238)

Any pointers on how to approach this problem?

Thanks!

Regards,
Martin Seebach
