> Using the following entities, when a simple single entry aCase -> aText ->

> observed when this object tree is persisted
> @Entity

> @Id
> @GeneratedValue(strategy=GenerationType.IDENTITY)
> private int id;
> @OneToOne(fetch=FetchType.LAZY, mappedBy="aCase",
> cascade=CascadeType.MERGE)

> @Entity
> public class AText {
> @Id
> @GeneratedValue(strategy=GenerationType.IDENTITY)
> private int id;
> @OneToOne(fetch=FetchType.LAZY, cascade=CascadeType.MERGE)

> private ACase aCase;
> @OneToMany(targetEntity=AEvident.class, mappedBy="aText",
> cascade=CascadeType.MERGE)
> private Set<AEvident> aEvidents = new HashSet<AEvident>();
> @Column(name="ACASE_ID", insertable=false, updatable=false, unique=true)
> private int aCaseId; // <<< this field is not updated to the
> associated aCase.id value after aText instance is persisted/merged.

> when aEvident instance is persisted in the same transaction, the INSERT used
