Normarize rule constraints for property reactivity and indexing --------------------------------------------------------------- Key: DROOLS-4956 URL: https://issues.redhat.com/browse/DROOLS-4956 Project: Drools Issue Type: Bug Components: core engine, executable model Affects Versions: 7.31.0.Final Reporter: Toshiya Kobayashi Assignee: Toshiya Kobayashi Priority: Major Having a constraint like {code:java} Person(name == $customer) {code} is not really the same thing as {code:java} Person($customer == name) {code} In the second case not only you don't have property reactivity, but also you don't have indexing. This an inconsistent behaviour and hoping to fix it with a "normalization" phase where the second constraint got rewritten like the first before being analyzed by property reactivity and indexing.
