Hi,
how can i serializable a EClassImpl ? I have problems with the remoting because the EClassImpl is not serializable.
Caused by: java.io.NotSerializableException: org.eclipse.emf.ecore.impl.EClassImpl

Hi,
I don't know much of your setup but it seems that the exception is thrown on the client when de-serializing correct?
Teneo replaces standard EMF ELists to give them extra persistence behavior, it seems that the Teneo EclipseLink classes
are not present on the client somehow. (but maybe I don't understand the exception or setup....).
