Querying a @OneToOne to an entity that inherit a @MappedSuperclass, the @DiscriminatorValue isn't used ------------------------------------------------------------------------------------------------------ Key: ANN-774 URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN-774 Project: Hibernate Annotations Issue Type: Bug Components: binder Affects Versions: 3.4.0.GA Reporter: Diego Plentz Priority: Critical If you have a class with a @OneToOne relation to an entity that inherit a @MappedSuperclass, and you do a query like the following, the @DiscriminatorValue isn't used if it's mapped eagerly. Criteria c = getSession().createCriteria(Foo.class) .createAlias("relatedOneToOne", "relatedOneToOne"); ----- @Entity public class Foo { @OneToOne(fetch = FetchType.LAZY) @JoinColumn(name = "cdfoo") private RelatedOneToOne relatedOneToOne; ... } ----- @Entity @Table(name = "bar") @Inheritance(strategy=InheritanceType.SINGLE_TABLE) @DiscriminatorColumn( name="cddiscriminator", discriminatorType=DiscriminatorType.INTEGER) public class Father { .. } ----- @Entity @DiscriminatorValue("3") public class RelatedOneToOne extends Father { ... } If you let the association to load "lazyly", it works and the DiscriminatorValue is used in the generated sql. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira
