Hi all,

I am having some problem with lazy loading. Here is an example of my mappings

@Entity
public class GrandParent {
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private Long id;

@OneToMany(mappedBy = "grandParent", cascade = { CascadeType.ALL })
@org.hibernate.annotations.Cascade({ org.hibernate.annotations.CascadeType.DELETE_ORPHAN })
private Set<GrandParentParent> grandParentParents = new HashSet<GrandParentParent>();
}

@Entity
public class GrandParentParent {
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private Long id;

@ManyToOne(fetch = FetchType.LAZY, cascade = { CascadeType.ALL })
@JoinColumn(name = "parent_id")
private Parent parent;

@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name = "grandParent_id")
private GrandParent grandParent;
}

@Entity
public class Parent extends {
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private Long id;

@OneToMany(mappedBy = "parent", fetch = FetchType.LAZY, cascade = CascadeType.ALL)
private Set<GrandParentParent> grandParentParents = new HashSet<GrandParentParent>();
}


public FamilyVo load(Long idGrandParent ,Long idParent) {
FamilyVo vo = new FamilyVo();
GrandParent grandParent = this.loadGrandParent(idGrandParent );
Parent parent = this.loadParent(idParent);

vo.setGrandParent(grandParent);
vo.setParent(parent);
return vo;
}

In the same transaction I want to load an object of class GrandParent but I don´t want to load de collection of GrandParentParent, then I want to load an object of class Parent that is member of collection GrandParentParent but this objet has proxy CGLIB and later in the presentation layer I get LazyInitializationException.
I think happen because I load first the object of class GrandParent that has in its collection the object of class Parent, it is in the Session.

Any suggestion???

Thank you in advance
