Based on testing expiring an event does no remove it from working memory. What is the best way to manage working memory in the case that after a period of X seconds you want the event removed? Would you simply write a rule that would do a retract after a certain window i.e rule "Closed Connection Occured" when $e:Event(connectionEventType == ConnectionEventType.CLOSE this after [20s] this) then retract($e); end -- View this message in context: http://drools.46999.n3.nabble.com/expires-tp4020117.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
