[rules-users] temporal operator workaround

Hi, I want to fomulate in the LHS something like: after an event happened another event of this kind did not happen for a specified time (somewhere externally defined). Unfortunatly, the obvious solution with the temporal operator 'after': --------------------------------------------------------------------- rule "rule temporal 1" ruleflow-group "g1" when $event : TestEvent($id: id) not( TestEvent(eval($id != id), this after[0ms,5000ms] $event ) ) then System.out.println( "Alarm " + $event.getId()); end --------------------------------------------------------------------- does not work here, because the specified time has to be hardcoded ( http://drools-java-rules-engine.46999.n3.nabble.com/Using-variables-in-Te... http://drools-java-rules-engine.46999.n3.nabble.com/Using-variables-in-Te... ) Is there a way to work around this limitation in this special case? I considered a polling approach with timers, but then I dont know how to stop the timer after firing the rule. Thanks in advance for your time.
