[rules-users] lock-on-active, why keeps evaluating?

[Edson Tirelli]

    Lock-on-active does not prevent rule evaluation. It prevents only rule
activation.

    The reason nodes are still evaluated is because Rete eagerly calculates
all partial matches, because as soon as you move your execution to another
group, the previously locked group will start activating rules again and so
the partial matches are already calculated. I understand that this might not
be desired in some cases, but that is how rete in general works.
