org.apache.openjpa.persistence.InvalidStateException: Encountered unmanaged object "au.com.combined.domain.Status-1" in life cycle state unmanaged while cascading persistence via field "au.com.combined.domain.AHistory.status" during flush. However, this field does not allow cascade persist. You cannot flush unmanaged objects or graphs that have persistent associations to unmanaged objects.
Suggested actions: a) Set the cascade attribute for this field to CascadeType.PERSIST or CascadeType.ALL (JPA annotations) or "persist" or "all" (JPA orm.xml),
b) enable cascade-persist globally,
c) manually persist the related field value prior to flushing.
d) if the reference belongs to another context, allow reference to it by setting StoreContext.setAllowReferenceToSiblingContext().
