      Description

      When a merge is done on a new object with an Id that contains an Entity, the following exception occurs:

      <openjpa-2.2.1-SNAPSHOT-r422266:1292578 nonfatal user error> org.apache.openjpa.persistence.InvalidStateException: Attempt to change a primary key field of an instance that already has a final object id. Only new, unflushed instances whose id you have not retrieved can have their primary keys changed.

      ...

      During the merge, a copy is made of the original object, with a copy of the key fields. But, if a key field is an Entity, it is not copied, causing this exception in later processing. The fix is to attach this field immediately after the original object is copied.
