IllegalStateException with Hibernate 4 and ManyToOne cascading

Question

I\'ve got those two classes

MyItem Object:

@Entity
public class MyItem implements Serializable {

    @Id
    private Integer id;
    @ManyToOne(casc         


        

Answer 1

Had the same exception (hibernate 4.3.0.CR2) tiring to save a object which is having two copies of a child object, got fixed by, in the entity from :

@OneToOne(cascade = CascadeType.MERGE)
private User reporter;
@OneToOne(cascade = CascadeType.MERGE)
private User assignedto;

to just,

@OneToOne
private User reporter;
@OneToOne
private User assignedto;

i don't know the reason though
