Hi, I am desperately trying to figure out how to express the following: Having a set of object names, say (a,b,c) I want to write a rule firing when there are no objects in working memory with name equals to at least one name from the set.
In other words I want to say: fire if there are no objects with name 'a', or no objects with name 'b' or no objects with name 'c'. The rule "not Object(name in('a', 'b', 'c'))" only fires if none of the objects exist. What I need is different though. Any help greatly appreciated. Thanks a lot. -- View this message in context: http://drools-java-rules-engine.46999.n3.nabble.com/Not-exists-on-at-least-one-element-from-the-set-tp916375p916375.html Sent from the Drools - User mailing list archive at Nabble.com. _______________________________________________ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
