Re: [rules-users] Trying to get Sliding Windows to work

Still trying to get sliding windows to work (basing my code off of the Eclipse supplied "Hello World" example). I don't think I fully understand how it works yet so I'm trying to simplify things even further by writing a simple rule that is meant to say: if (current_message = "Hello" AND exists( goodbye_message within sliding_window(3 seconds) )) then print("There was a GOODBYE message before the HELLO message." ) In other words: This rule should fire if the current Hello World message was preceeded within 3 seconds by a goodbye message. --------------------------------------------------------------------------------------------------- I wrote a new rule for this: declare Message @role( event ) end rule "Goodbye before Hello World" when Message( status == Message.HELLO ) exists( Message( status == Message.GOODBYE ) over window:time( 3s ) ) then System.out.println( "There was a GOODBYE message before the HELLO message." ); end --------------------------------------------------------------------------------------------------- To send the messages: (ksession is a StatefulKnowledgeSession) ... ksession.insert(goodbye_message); ksession.fireAllRules(); Thread.sleep(5000); ksession.insert(hello_message); ksession.fireAllRules(); ... --------------------------------------------------------------------------------------------------- I expect to get nothing back since I sent the Hello message 5 seconds after the goodbye message (outside the sliding window of 3 seconds). But, for some reason the rule fires and I get one: "There was a GOODBYE message before the HELLO message." Any help would be greatly appreciated.
