Hi,

I am getting this error when I attempt to save a child which has a unique composite key (sequence generated) but thesame PK. The issue only occurs when I try to save more than one child element with thesame child_key. Below is ths code. Please let me know any suggestions you may have. Been struggling with this for quite sometime now

@Entity
public class Parent implements Serializable {

@Column(name="PARENT_KEY", nullable=false)
@GeneratedValue(strategy=GenerationType.SEQUENCE, generator="ceremonyRecipientSeq")
@SequenceGenerator(name="ceremonyRecipientSeq", sequenceName="PARENT_KEY_SEQ")
private int parentKey

@OneToMany(cascade = {CascadeType.ALL})
@LazyCollection(LazyCollectionOption.FALSE)
@JoinColumn(name = "PARENT_KEY", nullable=false)
private List<Child> children= new ArrayList<Child>();

//getter, setters
.....
}

@Entity
public class Child implements Serializable{

@Id
@Column(name="CHILD_KEY", nullable=false)
private String childKey;

//getter, setters
.....
}
