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

[arun1979]

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
