[rules-users] drools-[slidingTimeCount]

Hi! I'm trying to use a sliding time fro count a facts with a condition. I'have set a stream mode. In test, with pseudo clock active, set this to current Time (it's correct?), declare a fact type in drl with declare MyFact (i've a javabean) @role(event) @timestamp(myTimestamp) end attribute type of myTimestamp must be long or Date? I've tried with both but nothing, engine count all fact ex: n fact in x days ago from now, the statement over window:time(1s) result always n fact. why? in when: // $o : Order(<condition>) $nRic : Number(intValue<maxRic) from accumulate($n: Order(this==$o) over window:time(1s),count($n)) ps. if i set a real clock altough a pseudo, in runTime i've a ClassCastExc. to JdkTimerService Thanks in advance. *Francesco*
