Description

When deleting an object with a flattened read-only relationship an exception is thrown:

Caused by: org.apache.cayenne.CayenneRuntimeException: [v.3.0.1 Sep 06 2010 15:09:38] Cannot unset the read-only flattened relationship runtimeRelationship0

It might be the same issue as CAY-784, but I haven't looked at the code yet.
