Hi there,

I'm working on a client/server rcp application, using emf, teneo, hibernate.
What I wish for is a persistent emf model, that has a one-to-many reference to a non-peristent emf-object... the non-persistent object will be created on the server-side when necessary and "shipped" to the client attached to its container, therefore it needs to be serialized by emf... which is way emf/jpa transient annotations won't solve my problems...

Is there a way of somehow telling teneo via annotations to not generate hibernate mappings for specific objects/references? Or how are these problems usually solved?

Thanks,
Roman

Hi Roman,
You can set the @Transient annotation on:
- an EClass: then instances of the EClass will not be mapped to hibernate, ereferences to this EClass will also be
considered as transient and are not mapped
- an EStructuralFeature: in this case the efeature is not mapped.
