> I have a rule that accumulate fact into sliding window.  When the count get to a certain threshold the rule should be activated.  After the window time is over, I expect that the rule will not fired anymore.  The counter of the fact is report as 0, but still the rule is being executed.
> drl :
> package com.sample;
> import com.sample.WindowLength.FactTest;
> declare FactTest
>   @role( event )  
> end
>  
> rule "A500 : test"
> when
> 		// count devices per tag id
> 		$counter : Number( intValue >= 2 ) from accumulate (
> 			 $d : FactTest() over window:time(1m), count($d))
> 			
> then
> 		System.out.println("A500: Rule is fired, count = " + $counter + " *********");
> end
> scenario:
> ksession.insert(new FactTest());
> ksession.fireAllRules();
> ksession.insert(new FactTest());
> ksession.fireAllRules();
> ksession.insert(new FactTest());
> ksession.fireAllRules();
> SessionPseudoClock clock = ksession.getSessionClock();
> clock.advanceTime(1, TimeUnit.MINUTES );
> ksession.fireAllRules();
> Result:
> A500: Rule is fired, count = 2 *********
> A500: Rule is fired, count = 3 *********
> A500: Rule is fired, count = 0 *********
