Interval-based events must have a property for their duration (in ms), not the end time.

@duration(duration)
duration : long

-W

Hi,

I've following event declarations and rule:



declare Event 

    @role(event) 

    @timestamp(datetime)

    datetime : Date

    name : String

end



declare Contest

    @role(event)

    @timestamp (startTimestamp)

    startTimestamp : Date

    endTimestamp : Date

end



rule "Contest"

no-loop

when    

    $e : Event(name == "event1")

    $contest : Contest(this includes $e)

then 

    System.out.println("rule Contest fired");

end



The timestamps with Event and Contest objects are set as follows (before insert in state-full session):



           // for Contest object

           Calendar c = Calendar.getInstance();

            c.set(2011, 7, 1);

            contestType.set(contest, "startTimestamp", new Date(c.getTimeInMillis()));

            c.set(2011, 7, 31);

            contestType.set(contest, "endTimestamp", new Date(c.getTimeInMillis()));



            // for Event object

             c.set(2011, 7, 3);

             eventType.set(event, "datetime", new Date(c.getTimeInMillis()));



The condition "this includes $e" in LHS doesn't get evaluated to true and RHS doesn't get executed.



If I change it to "$contest.startTimestamp before $e, 
$contest.endTimestamp after $e"  which has the same meaning then it 
works fine.

Please help in resolving the issue.



Thanks & Regards,

Neelesh
