"unable to locate static metamodel field" caused by MetadataContext.applyIdMetadata(PersistentClass, EntityTypeImpl) -------------------------------------------------------------------------------------------------------------------- Key: HHH-6804 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-6804 Project: Hibernate Core Issue Type: Bug Components: metamodel Affects Versions: 4.0.0.CR5, 3.6.3 Environment: Hibernate 3.6.3 Reporter: Karl Rhenius Attachments: hibernate_issue.zip Hello, Hibernate throws the following error on startup: MetadataContext.registerAttribute:421 - Unable to locate static metamodel field : org.foo.test.inheritance.singlePk.MoviePoster_#posterId The entity MoviePoster is a subclass of the entity Poster. Poster uses the @IdClass annotation to define a primary key class and has a field posterId tagged with @Id After some debugging I found this piece of code in MetadataContext, that adds the property of my id class to the metadata-list of MoviePoster, because the id class has only one property: Line 251: else { final KeyValue value = persistentClass.getIdentifier(); if (value instanceof Component ) { final Component component = ( Component ) value; if ( component.getPropertySpan() > 1 ) { //FIXME we are an Hibernate embedded id (ie not type) } else { //FIXME take care of declared vs non declared property jpaEntityType.getBuilder().applyIdAttribute( attributeFactory.buildIdAttribute( jpaEntityType, (Property) component.getPropertyIterator().next() ) ); } } } I'm not quite sure, if this is a bug or improvement, because I couldn't find any problems so far. This bug seems to be related to HHH-5024, but the testcases are quite different. The attached file contains a testcase with a single-column and multi-column id-class. -- This message is automatically generated by JIRA.
