[rules-users] Subclasses matche superclasses problem.

Hi everybody, I have a class Car which is superclass for class ConvertibleCar, two rules (described below) and a ConvertibleCar fact in working memory that causes both rules to fire, resulting this way an unwanted change to the car`s attribute and an infinite loop. How do I evitate this problem: the specialization class fact to not match its superclass column in a rule? ConvertibleCar car =new ConvertibleCar(10000); rule "rule-1" when $car:Convertible() then $car.setPotentialTheftRating("high"); end rule "rule-2" when $car:Car(price<20000) then $car.setPotentialTheftRating("low"); end Best regards, Oana --------------------------------- The fish are biting.
