Re: [rules-users] when should we the not operator.

I am using the stream mode as depicted by the code below *configuration.setOption(EventProcessingOption.STREAM); * Both EventX and EventY are of the same type. Actually my mistake the rule is like this declare EventX @role( event ) @timestamp( eventDate ) @expires( 2m ) end rule "test rule" no-loop when event : EventX(eventType == 'XYZ', $oId :Id) not ( EventX(eventType == 'ABC', Id == $oId, this after[0s,8s] event)) then //fire the rule. code never reaches here if EventX of type 'ABC' does not occur at all end -- View this message in context: http://drools.46999.n3.nabble.com/when-should-we-the-not-operator-tp32259...
