Anyone ever seen this error in the IDE: Severity and Description Path Resource Location Creation Time Id Operator '50' does not exist for StringEvaluator RtvDecisionEngine/src/rules/com/circuitcity/rtvcrms/rules rtv.drl Unknown 1179954317638 29080 And if so what do you do about it? My rules file is just under 1000 lines [and growing] and shows no other errors.
