> 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!
