Hi,
I'm trying to generate
- .genmodel
- orm.xml and
- Model/Edit Code
from an Ecore file with Teneo-EclipseLink.
This is working well for single entities, but my one-to-many relationship
fails. EclipseLink warns as follows:
[EL Warning]: Element [protected org.eclipse.emf.common.util.EList
simple.impl.WriterImpl.books] within entity class [class
simple.impl.WriterImpl] uses a collection type [interface
org.eclipse.emf.common.util.EList] when the JPA specification only
supports java.util.Collection, java.util.Set, java.util.List, or
java.util.Map. This type is supported with eager loading; using lazy
loading with this collection type requires additional configuration and an
IndirectContainer implementation that extends [interface
org.eclipse.emf.common.util.EList] or setting the mapping to use basic
indirection and the type to be ValueholderInterface.
I don't know how to set "the mapping to use basic indirection and the type
to be ValueholderInterface" in the Ecore file, strictly speaking. ;-)
BTW: Contents of the EclipseCon 2009 session
http://www.eclipsecon.org/2009/sessions?id=614
(Teneo--Integrating EMF & EclipseLink for Model-Driven Development with
Persistence)
are looking very promising, but I wasn't able to find any examples or
other uploaded content for that session yet. :-(
But maybe one could give me a hint how to fix my ecore file (or provide me
with a working example):

OK, versions are highly experimental, but I think my error is rather
"fundamental" ;-)
TIA

I have the same issue with OneToMany relations (even if the exception
message looks a little bit changed) and the EMF-Teneo-JPA application stop
working. A error message dialog popped up in Eclipse IDE and the following
exception are thrown:

Hi Antonel,
Can you post the ecore and the orm you get? Persistence should work out-of-the-box (except for setting id and version
eattributes that is), so for one-to-manies you should not get these problems.
It is getting towards mid-night here so it will probably be tomorrow before I or other Teneo-EclipseLink committers can
take a look at it...
