"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

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.
