Hi all,

I have problem with cascading persistence with the following code consisting of 2 annotated classes Listing and ListingLocation.
if a Listing instance is set to the listing2 of a ListingLocation instance, the Listing instance will be automatically persisted when I save the ListingLocation instance
if a Listing instance is only set to the listing1 of a ListingLocation instance, the Listing instance will NOT be automatically persisted when I save the ListingLocation instance
listing1 is also used as the primary and foreign key.

Would any one please tell me how should I code to get listing1 to automatically get persisted?

Thank you very much.

Code:
@Entity
@Table
@Access(AccessType.FIELD)
public class Listing implements Serializable {
@Id
@GeneratedValue
private long id;
@Column(columnDefinition = "DECIMAL(10,2)")
private double price;
...}


Code:
@Entity
@Table
@Access(AccessType.FIELD)
public class ListingLocation implements Serializable {
  @Id
          @OneToOne()
          @Cascade(value={ CascadeType.PERSIST, CascadeType.SAVE_UPDATE })
          @ForeignKey(name = "FK_ID")
          @JoinColumn(name = "ID", referencedColumnName = "id", unique = true, updatable = false, insertable = false)
          private Listing listing1;
      @Column(name = "address")
          private String address;
      @OneToOne()
          @Cascade(value={ CascadeType.PERSIST, CascadeType.SAVE_UPDATE })
          @JoinColumn(name = "List2", referencedColumnName = "id", nullable = true)
          private Listing listing2;
...}
