Richard Rak commented on OPENJPA-1422:
--------------------------------------

Here is the stack trace when executing the given test case on 1.2.1:

<openjpa-1.2.1-rexported nonfatal user error> org.apache.openjpa.persistence.InvalidStateException: Encountered unmanaged object in persistent field "org.apache.openjpa.persistence.jdbc.maps.embeddedkey.Folio.folioItems<key:class org.apache.openjpa.persistence.jdbc.maps.embeddedkey.FolioItemPK>" during flush.  However, this field does not allow cascade persist. Set the cascade attribute for this field to CascadeType.PERSIST or CascadeType.ALL (JPA annotations) or "persist" or "all" (JPA orm.xml), or enable cascade-persist globally, or manually persist the related field value prior to flushing. You cannot flush unmanaged objects or graphs that have persistent associations to unmanaged objects.
