Description Martin Taal CLA 2011-12-05 06:00:58 EST 
See this question on the form:
http://www.eclipse.org/forums/index.php/mv/msg/263238/760792/

When having an external annotation it makes sense to annotate the refered to class as being transient to prevent a table from being created in the database. This results however in a NPE (see the forum post), as the ereference is set to be transient and no one-to-many annotation is generated.
Comment 1 Martin Taal CLA 2011-12-05 15:09:48 EST 
In latest build: an eclass can be annotated with @External, in that case no table will be created for the EClass and all ereferences to it are assumed to be external (they will automatically get an External annotation):
