Re: [rules-users] Multipattern collect

Is a multipattern collect supported? I have a rule which finds all 2 topics and all the students they share if there is at least 1 such student: rule "calculateTopicConflict" when $leftTopic : Topic($id : id); $rightTopic : Topic(id > $id); $studentSet : HashSet( size > 0 ) from collect( $student : Student(), $leftTopic.studentList contains $student, $rightTopic.studentList contains $student ); then insertLogical(new TopicConflict($leftTopic , $rightTopic , $studentSet)); end This won't compile: Caused by: org.drools.rule.InvalidRulePackage: [29,36]: unknown:29:36 mismatched token: [@370,1504:1504=',',<11>,29:36]; expecting type RIGHT_PAREN[30,39]: unknown:30:39 mismatched token: [@376,1545:1552='contains',<49>,30:39]; expecting type LEFT_PAREN[30,48]: unknown:30:48 Unexpected token '$student' at org.drools.rule.Package.checkValidity(Package.java:424) Is a multipattern collect supported?
