Re: [rules-users] RE : Identity Mode?

Hi, I think you are talking about the assert behavior: KnowledgeBaseConfiguration configuration = KnowledgeBaseFactory.newKnowledgeBaseConfiguration(); configuration.setOption(AssertBehaviorOption.EQUALITY); But I think you will have to add a condition like... : p1 : Person() Person(this != p1) ... to make it work like you intended.

If I have a rule such as: When Person() Person() Then System.out.println("There are two people!") End I only want this to fire if there are two (or more) Person objects inserted into the session, however as default drools will fire even when there is just one Person object inserted (i.e. both Person patterns get matched to the same fact). I seem to remember there is a flag I can set that swaps between these two types of behavior, and seem to remember it's to do with Identity/Equality mode. However, I can't remember how or where to do this. Any help on this would be greatly appreciated.. Cheers, Rich. P.S I realise that I could add constraints to the patterns to explicitly check that the facts aren't the same.. however I'd rather not have to do that as I'm trying to make it as simple as possible for users to create rules.. -- View this message in context: http://drools.46999.n3.nabble.com/Identity-Mode-tp4024428.html Sent from the Drools: User forum mailing list archive at Nabble.com. _______________________________________________ rules-users mailing list rules-users(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users _______________________________________________ rules-users mailing list rules-users(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
