Re: [rules-users] Collect and hibernate

Did you tried this? when $m : MessageAsEvent(uuid=="mesC:7") $o : MessageAsEvent(uuid=="mesC:7", id!=$m.id) from hibernateSession.createQuery("from MessageAsEvent where serial=?").setParameter(0,$m.serial).list() then insert($o) end In any case, collect should work too. Which version of drools are you using?
