A rule always fires with executable model for a constraint which has extra parentheses -------------------------------------------------------------------------------------- Key: DROOLS-5107 URL: https://issues.redhat.com/browse/DROOLS-5107 Project: Drools Issue Type: Bug Components: executable model Affects Versions: 7.33.0.Final Reporter: Toshiya Kobayashi Assignee: Toshiya Kobayashi Priority: Major When you have a constraint with extra parentheses, {noformat} $p : Person((age > 30)) {noformat} executable-model generates a pattern without a constraint expr method so it always fires. {code:java} public static org.drools.model.Rule rule_R() { final org.drools.model.Variable<org.drools.modelcompiler.domain.Person> var_$p = D.declarationOf(org.drools.modelcompiler.domain.Person.class, DomainClassesMetadataFBDA1ED637C8B60C741C0BDB502EB8F0.org_drools_modelcompiler_domain_Person_Metadata_INSTANCE, "$p"); org.drools.model.Rule rule = D.rule("R").build(D.pattern(var_$p), D.execute(() -> { { } })); return rule; } {code}
