Hallo,

I needed to pass an EObject for a RMI. Therefore I had to nake my generated model classes implement java.io.Serializable. I managed that by creating a root interface called SerializableEObject extending EObject and Serializable. All my model Interfaces extend SerializableEObject. So far so good, I was able to pass the Objects.

Now comes the strange part:
My passed Object has a Containment Reference. Before passing the EObject the eContainer()-Method return the desired container Object. After the EObject is the eContainer-Reference is null. Is there a way to circumvent that?

Thanks for any help, Sebastian

Sebastien,

EObjectImpl isn't marked serializeable, so I assume its fields aren't
being serialized. You'd need to implement specialized read/write logic
in your derived implementation classes...
