Re: [rules-users] threw error java.lang.ClassCastException: org.drools.reteoo.FromNode$FromMemory cannot be cast to org.drools.reteoo.BetaMemory

Ejaz, without seeing the "original" rule and the "updated-so-that-it-will-not-fire" version of the same, there is little we can do. Are you by chance replacing something like Pattern( field == $previouslyBoundVariable ) with ? Pattern( field == $previouslyBoundVariable ) from $nowhere Problem is, there could be zillions of possibly suspect cases, and nobody in the community has the time to try them all. I understand that you may not be in a position to release your rules to the public, but it's common practice to "de-identify" rules by replacing class names and literal values with "Foos" and "Bars", so to preserve the structure of the logic without exposing its meaning - which out of its context would probably make no sense anyway.
