[rules-users] drools cannot be resolved

[Edson Tirelli]

   Raffaele,

   The LHS of a rule should have no "side effects", like creating the list.
That is because the engine may fire the rule any time it is best suited to
fire and we shouldn't try to control that. You will also lose expressiveness
doing such things.
   My advice for you is to rethink your rules, maybe creating multiple rules
if it is the case, having in mind that the LHS of a rule is a pattern
matching condition saying "when" the rule should fire, and only the RHS of
the rules should execute any real action.

    Hope it helps,
      Edson
