[rules-users] Drools firing wrong rules

[Edson Tirelli]

   It is not possible to know, looking only at the screenshots that you
sent, what is the problem. Are the values null at the time you insert them
into the session? If you modify them after inserting them into the session,
are you properly notifying the engine?
