[jboss-jira] [JBoss JIRA] Assigned: (JBRULES-2671) Allow relational operators for String

Allow relational operators for String ------------------------------------- Key: JBRULES-2671 URL: https://issues.jboss.org/browse/JBRULES-2671 Project: Drools Issue Type: Feature Request Security Level: Public(Everyone can see) Components: drools-core (expert) Affects Versions: 5.1.0.FINAL Reporter: Toshiya Kobayashi Assignee: Edson Tirelli Attachments: JBRULES-2671-testcase.patch, JBRULES-2671.patch Currently you cannot use relational operators for String fields. e.g. MyFact(name > "bbb") org.drools.base.evaluators.ComparableEvaluatorsDefinition.evaluators has entries for ValueType.OBJECT_TYPE, but not for ValueType.STRING_TYPE. So it results in DescrBuildError: ========= Evaluator '>' does not support type 'ValueType = 'String' : [Rule name='Your First Rule'] Unable to create restriction '[LiteralRestriction: > bbb]' for field 'name' in the rule 'Your First Rule' : [Rule name='Your First Rule'] ========= According to docs: 4.8.3.1.1.3.1. Operators "Other relational operatory may be used whenever the type values are ordered;" http://downloads.jboss.com/drools/docs/5.1.0.34406.FINAL/drools-expert/ht... It is desirable to allow relational operators for String fields as String is Comparable.
