Thanks I made a search and it seems it is controlled by a config to switch between identity or equality. Since I can only write rules, I can't enjoy the advantage of that.
I ended up writing a retract rule to retract the same (equal) object from memory with higher salience. So everytime some rules insert a new object, this rule will fire to remove the object if they have the same id. -- View this message in context: http://drools.46999.n3.nabble.com/Any-easy-way-to-avoid-inserting-same-id-object-into-memory-tp4027102p4027182.html Sent from the Drools: User forum mailing list archive at Nabble.com. _______________________________________________ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
