Dmitry Pavlov updated OPENJPA-2144:
-----------------------------------
Description:
Partially defined entity:
@Entity
@IdClass(Node2.ID.class)
public class Node2 {
@Id
@GeneratedValue
private long id;
@Id private int region = 1;
@Id private int district = 2;
@ManyToOne(fetch = LAZY)
@JoinColumns({
@JoinColumn(name = "PARENT_ID", referencedColumnName =
"ID"),
@JoinColumn(name = "REGION", referencedColumnName =
"REGION"),
@JoinColumn(name = "DISTRICT", referencedColumnName =
"DISTRICT") })
private Node2 parent;
@OneToMany(mappedBy = "parent", cascade = ALL, fetch = LAZY)
private List<Node2> nodes = new ArrayList<Node2>();
// getters, setters, etc.
// full text will be attached as a unit test:
TestRecursiveRelationshipsWithIdClass.testTree()
An attempt to use a such entity leads to NullPointerException :
