When I tried using ElementCollection of Embeddables with TexoResource I got an eclipselink error complaining that the Embeddable object is not a Entity.

Are Element Collections not supported with the TexoResource?

Hi Chris,
ElementCollections should be supported, or it might be a bug... Can you check if the orm.xml/JPA annotations are indeed
correct?

I've added to a simplified test case with a Book that has an Element Collection of Authors. Author being embeddable, generates the following code:

@ElementCollection()
@CollectionTable(joinColumns = { @JoinColumn(name = "BOOK_ID", referencedColumnName = "ID") }, name = "AUTHOR")
@OneToMany(cascade = { CascadeType.ALL })
private List<Author> authors = new ArrayList<Author>();

I thought maybe the OneToMany interfered and removed it from the JPA annotation but it did not change the result:

Object: Author  [name: Hermann Melville] is not a known entity type.
[EL Config]: Using OSGi initializer: [org.eclipse.persistence.internal.jpa.deployment.osgi.equinox.EquinoxInitializer].
java.lang.IllegalArgumentException: Object: Author  [name: Hermann Melville] is not a known entity type.
	at org.eclipse.persistence.internal.sessions.UnitOfWorkImpl.registerNewObjectForPersist(UnitOfWorkImpl.java:4176)
	at org.eclipse.persistence.internal.jpa.EntityManagerImpl.persist(EntityManagerImpl.java:451)
	at org.eclipse.emf.texo.server.store.BaseDao.insert(BaseDao.java:204)
	at org.eclipse.emf.texo.server.store.EntityManagerObjectStore.insert(EntityManagerObjectStore.java:108)
	at org.eclipse.emf.texo.server.store.EPersistenceService.persist(EPersistenceService.java:86)
	at org.eclipse.emf.texo.store.TexoResource.save(TexoResource.java:133)

It may be a bug, but at this point I'm not experienced enough to say that I've not configured something improperly in the orm.annotationsmodel or ecore.

Hi Chris,
Ha now I understand, Texo does not know that Author is embedded so tries to explicitly insert it. Can you enter a
bugzilla for this? And attach your example project to it?
