Hi everyone, I need to perform a count of facts, but my problem is that the facts are nested inside other facts My model would be something like this a class called Cuscar that is like the main class that contains the other facts inside the class Cuscar I have a list called segmentGroup7 (private List<SegmentGroup7> segmentGroup7), and inside each SegmentGroup7 I have another list (List<SegmentGroup8> segmentGroup8) with this rule Im able to get all the facts of the type segmentGroup8 $cuscar : Cuscar(); $group7: SegmentGroup7() from $cuscar.segmentGroup7; $group8 : SegmentGroup8() from $group7.segmentGroup8; but I would like to count the number of facts, any idea how?? thanks so much for your help :) -- View this message in context: http://drools.46999.n3.nabble.com/counting-Facts-tp3192513p3192513.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

Thanks man it works perfectly... :) But I have another scenario where inside each SegmentGroup7 theres a SegmentGroup14 and inside this group I have to verify a value inside another class called GoodsItemDetails, as in my last post I can "collect" all the occurrences with this code : $cuscar : Cuscar(); $group7: SegmentGroup7() from $cuscar.segmentGroup7; $group8 : SegmentGroup8() from $group7.segmentGroup8; $group14 : SegmentGroup14() from $group8.segmentGroup14; GoodsItemDetails(c7064 == "9" from $group14.gid ); but again I want to count the number of facts, is there a way to do this?? thanks so much in advance for your suggestions :) -- View this message in context: http://drools.46999.n3.nabble.com/counting-Facts-tp3192513p3197756.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

if I insert int the WM the SegmentGruoup7 (that inside contains the SegmentGroup8) and then I insert SegmentGroup8 in the WM, wouldnt that be duplicating the information? or drools just holds a reference to this classes,
