[hibernate-issues] [Hibernate-JIRA] Assigned: (HHH-5393) @MapKey with embeddable value

@MapKey with embeddable value ----------------------------- Key: HHH-5393 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5393 Project: Hibernate Core Issue Type: Bug Components: annotations Affects Versions: 3.5.3 Environment: Hibernate 3.5.3, PostgreSQL 8.4.3 Reporter: Harald Wellmann Map<Basic, Embeddable> does not work, when the map key is a persistent field of the value. The map key shall not be represented as a separate table column, this is why the example uses @MapKey and not @MapKeyColumn. Example: {code:java} @Embeddable public class LocalizedString { private String language; private String text; } @Entity public class MultilingualString { @Id private long id; @ElementCollection(fetch=FetchType.EAGER) @MapKey(name = "language") @CollectionTable(schema = "jpa", name = "multilingual_string_map", joinColumns = @JoinColumn(name = "string_id")) private Map<String, LocalizedString> map = new HashMap<String, LocalizedString>(); } {code} Hibernate appears to expect an Entity as map value: org.hibernate.AnnotationException: Associated class not found: LocalizedString Detailed discussion of this use case: http://hwellmann.blogspot.com/2010/07/jpa-20-mapping-map.html
