Re: [rules-users] Not and forall operator behaviour

Davide, Thank you for the clarification. My error was to interpret the "not" operator as an existential function (ie: "there is no such object that exists") and viewing the object as a unit, rather than, as you pointed out, logically manipulable. In light of that, the logical OR in place of the comma makes sense. Roger -- View this message in context: http://drools.46999.n3.nabble.com/Not-and-forall-operator-behaviour-tp402...
