Hi everybody, I'm new to drools and I would like to solve this simple situation: I have a rule which will fire when 3 or more events comes from entry-point with level > 4 in a 10s window: rule "Got 3 events" when not Alarm() t : Number(intValue > 2) from accumulate ( e : Event( level > 4) over window:time(10s) from entry-point "queue", count(e) ) then insert(new Alarm()); end This way if more events comes with level > 4 no more alarms are sent. I have another rule to retract Alarm object when more than 5 events comes with level < 6 in a 10s window: rule "Reset alarm" when a : Alarm() c : Number( intValue > 5) from accumulate ( e : Event( level < 6) over window:time(10s) from entry-point "queue", count(e) ) then retract(a); end The problem is that I got an infinite loop once I retract the Alarm object and a new is inserted by the first rule. How could I solve the problem? Probably a different approach but I'm still learning. -- View this message in context: http://drools.46999.n3.nabble.com/Insert-fact-to-be-used-as-semaphore-tp4...
