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
