[rules-users] timer and duration

[OlliSee]

Hello folks.

Got a new characteristic unveiled,...

if I have a rule like this (with Fusion in STREAM mode)...
(Sensor is a fact)

rule "Test"
       timer(int: 7s 7s)
       when
              $sensor : Sensor()		
	      Number($avg : doubleValue > 0.0) from accumulate
			(LoopDetectorEvent($vel : velocity, sensor == $sensor) over
window:time(7s), average($vel))
        then
              ...
end

...Drools fires the rule correctly every 7 seconds for each Sensor fact.
BUT, it sometimes fires twice for random Sensors.

This is of course not intended. Is this a bug or can this behaviour be
explained?
