[rules-users] Collect and hibernate

Hi again, I wish to have a rule that when an Event has a certain uuid then load into working memory all other events that have been received for this unit... So I write the rule: rule "Repeating" when $m : MessageAsEvent(uuid=="mesC:7") $others : LinkedList() from collect ( MessageAsEvent(uuid=="mesC:7", id!=$m.id) from hibernateSession.createQuery("from MessageAsEvent where serial=?").setParameter(0,$m.serial).list() ) then System.out.println("Gathering m="+$m+" data="+$others); end Audit log shows: (wish cut and paste would work from Eclipse audit view) <activationId>Repeating [131, 14]</activationId> <rule>Repeating FAN</rule> <declarations>$others=[MessageAsEvent:[124] uuid=mesC:7 serial=serial123 count=7, MessageAsEvent:[94] uuid=mesC:7 serial=serial123 count=7, MessageAsEvent:[64] uuid=mesC:7 serial=serial123 count=7, MessageAsEvent:[118] uuid=mesC:7 serial=serial123 count=7, MessageAsEvent:[112] uuid=mesC:7 serial=serial123 count=7, MessageAsEvent:[106] uuid=mesC:7 serial=serial123 count=7, MessageAsEvent:[100] uuid=mesC:7 serial=serial123 count=7, MessageAsEvent:[88] uuid=mesC:7 serial=serial123 count=7, MessageAsEvent:[82] uuid=mesC:7 serial=serial123 count=7, MessageAsEvent:[76] uuid=mesC:7 serial=serial123 count=7, MessageAsEvent:[70] uuid=mesC:7 serial=serial123 count=7, MessageAsEvent:[58] uuid=mesC:7 serial=serial123 count=7, MessageAsEvent:[52] uuid=mesC:7 serial=serial123 count=7, MessageAsEvent:[46] uuid=mesC:7 serial=serial123 count=7, MessageAsEvent:[40] uuid=mesC:7 serial=serial123 count=7, MessageAsEvent:[34] uuid=mesC:7 serial=serial123 count=7](131); $m=MessageAsEvent:[130] uuid=mesC:7 serial=serial123 count=7(14)</declarations> <ruleFlowGroup>Gathering</ruleFlowGroup> So, you can see that the rule fired with $others having all the data, and $m being the main uuid but the output of the rule is: Gathering m=MessageAsEvent:[130] uuid=mesC:7 serial=serial123 count=7 data=null so, the $others has been translated to a null. I'm trying to copy the Expert example: import java.util.LinkedList; rule "Send a message to all mothers" when $town : Town( name == 'Paris' ) $mothers : LinkedList() from collect( Person( gender == 'F', children > 0 ) from $town.getPeople() ) then # send a message to all mothers end which indicates that $mothers will be available in the RHS for reference, the audit log shows when the rule fires: <org.drools.audit.event.ActivationLogEvent> <type>6</type> <activationId>Repeating [-1, 14]</activationId> <rule>Repeating FAN</rule> <declarations>$m=MessageAsEvent:[130] uuid=mesC:7 serial=serial123 count=7(14)</declarations> <ruleFlowGroup>Gathering</ruleFlowGroup> What am I doing wrong? I basically want all the MessageAsEvent added to working memory, so later other rules will do work on all the events.
