Showing us the defclass and definstance calls might help, too. It's possible that your problem is related to problems with your objects's hashCode() and/or equals() method. If the hashCode of the object changes unexpectedly -- i.e., while it's installed in working memory as a definstance, without associated change events -- Jess's internal data structures can become corrupted. Furthermore, if your Bean class's equals and hashCode methods are not defined consistently -- i.e., you've overridden one, but not the other, so that their basic contract is violated -- again, Jess can become confused. Earlier versions of Jess were more prone to this than current ones. > > Hakim > > > Jess> (facts) > f-6 (MAIN::AlarmFaultData (assocEntityId1 1) (assocEntityId2 2) (assocEntityId3 0) >(class <External-Address:java.lang.Class>) (description "The Wave Interface of an >unprotected circuit is manually turned down.
