Re: [rules-users] Date arithmetic in “when” session

Hi, you shouldn't put part of the "if" or "when" part after the "then". Put all conditions after the "when" so the rule engine will evaluate them. I guess you mean to write something like (although I haven't tested this): rule "ITR Discard" when req : LowFareRequest( $reqTime : requestedDeparture.time) itr : AirItinerary( discarded == false ) flight : Flight( departure.time - 2 * 3600000 < $reqTime, departure.time + 4 * 3600000 > $reqTime) then System.out.println("discard true"); end Christine
