If am using a Stateful knowledge session with a rule flow group. I am inserting into working memory one instance of each class/type listed below. All of the rules fire except for rule 14. Rule 14 and 15 are very similar but for some reason only rule 15 fires. If I swap the physical order of 14 and 15 in the DRL file then rule 14 fires and 15 does NOT. If I change the order of the LHS conditions for rules 14 and 15 then both rules fire. I am assuming the order of the LHS conditions or physical order of the rules is irrelevant. Is that the case? If so, then can someone tell me what I’m doing wrong? //*******************Classes/Types*********************************** DRuleContext.java (annotated with @PropertyReactive): boolean elig; Date date; Person.java String typeID; String status; DDE (declared type in Drools.
