Re: [rules-users] Inserting elements of a list into a session from a rule consequence

I am trying to write a rule whose consequence loads several lists into the session. Each list contains a different type of class. What I would like to do (need to do as far as I can tell) is loop through the list and insert each element individually, rather than inserting the list as a whole. Is ther a way to do this in DRL? Here is my example rule: rule "Do we need to validate ONFI final action" when a : PackageMovementInfo( finalActionInd == "*", packageId == "AA") b : SubmissionsInfoForRules(subId == a.subId, amendment == false, onfiAssignmentId != null) then insert( new RuleFlag("Validate ONFI final action") ); insert( onfiService.getONFIAssignment(b.getSubId()) ); insert( onfiService.getONFIReviewers(b.getOnfiAssignmentId()) ); insert( onfiService.getONFIAttachments(b.getOnfiAssignmentId()) ); end The last two insert statements insert lists. A problem occurs in subsequent rules if I try to evaluate the contents of the lists. I've been getting a ClassCastException when lists are present for both the reviewers and attachments, because they are not the same class. Here is an example rule that causes a ClassCastException: rule "Validate ONFI final action - code 666" when RuleFlag(value == "Validate ONFI final action") a: PackageMovementInfo(actionCode == "666") b: ONFIAssignmentInfo(reviewType == "ES", subId == a.subId) $list : List( size > 0 ) ONFIReviewerInfo(notId == b.notId, revStatus == "CLO", reviewerRole == "PR") from $list then result.addMessage(a, "You can't do action code 666..." ); end What I need to do is either (1) load each element of the lists individually, or (2) rewrite "$list : List (size > 0)" to only pick up lists of a particular class. Is there a way to do either of these things from DRL? Or do I need to handle the loading outside of my rules (in the Java class that calls the rules).
