Disjunction over a set not working ---------------------------------- Key: JBRULES-2877 URL: https://issues.jboss.org/browse/JBRULES-2877 Project: Drools Issue Type: Bug Security Level: Public (Everyone can see) Affects Versions: 5.1.1.FINAL Reporter: Oliver Roess Assignee: Mark Proctor Hello there and a happy new year to everyone reading :) Why am I here again? Yep, got a problem. Don't know why it doesn't work. I'm using the latest snapshot version. So here it goes. A simple rule with conjunction and disjunction but over a set of events. when $ldes : Set(size == 2) from collect(LoopDetectorEvent() over window:length(2)) (or LoopDetectorEvent($t1 : transportation == "LKW", $id1 : eventID) from $ldes LoopDetectorEvent($t2 : transportation == "PKW", $id2 : eventID) from $ldes) LoopDetectorEvent($t3 : transportation == "BUS", $id3 : eventID) from $ldes So, what the rule says: fire when there's a BUS event plus either a LKW or PKW event in the set. But, instead I get a big exception. It's posted at the end. Interestingly, it works if I don't use the Set, like this... when (or $e1 : LoopDetectorEvent($t1 : transportation == "PKW", $id1 : eventID) over window:length(1) $e2 : LoopDetectorEvent($t2 : transportation == "LKW", $id2 : eventID) over window:length(1)) LoopDetectorEvent($t3 : transportation == "BUS", $id3 : eventID) over window:length(1) but that rule does not have the same meaning. So it's useless for me. Besides, it DOES work with the set if I just cut the third event out (the BUS event). What is wrong here? Thanks in advance. Kind regards!
