[hibernate-issues] [Hibernate-JIRA] Resolved: (HHH-7235) Support null NaturalId values in loadEntityIdByNaturalId query

Support null NaturalId values in loadEntityIdByNaturalId query -------------------------------------------------------------- Key: HHH-7235 URL: https://hibernate.onjira.com/browse/HHH-7235 Project: Hibernate ORM Issue Type: Improvement Components: core Affects Versions: 4.1.0, 4.1.1, 4.1.2 Reporter: Guenther Demetz Assignee: Steve Ebersole Labels: naturalId Fix For: 4.1.3 Original Estimate: 0.5h Time Spent: 56m Remaining Estimate: 0.5h As it is allowed to persist and commit null naturalId values (for example null String values), it would also be nice to can sucessful lookup for those values. Currently the where-clause of the lookup-query does not consider the eventuality of null values, which in sql require an extra handling (using 'is' keyword instead of '=' sign). The needed code change is simple, see pull request.
