Problem
Basically i have a One to Many relationship that works fine for create and add childs, but when i try to remove childs it throws this error, i'm using JPA Hibernate implementation.

Hibernate version:
Hibernate-Version: 3.2.6.ga
Product: Hibernate EntityManager Version: 3.3.1.GA
Spring-Version: 2.0.8

Mapping documents:
Coupon(One Side)
...
@Entity
@Table(name = "COUP_DTL")
public class Coupon implements Serializable {

/**
*
*/
...
@OneToMany(cascade = { CascadeType.ALL }, fetch = FetchType.LAZY, targetEntity = com.heb.coupon.model.Upc.class)
@Cascade(org.hibernate.annotations.CascadeType.DELETE_ORPHAN)
@JoinColumn(name = "COUP_ID", nullable = true)
private List<Upc> products;

Upc(Many side)
@Entity
@Table(name = "COUP_UPC")
@AttributeOverrides( {
@AttributeOverride(name = "coupId", column = @Column(name = "COUP_ID")),
@AttributeOverride(name = "retailUnitGtin", column = @Column(name = "RETL_UNTI_GTIN")) })
public class Upc implements Serializable {

/**
*
*/
@EmbeddedId
@ManyToOne
private CouponUpcCompositeId id;
@Column(name = "BUY_ITM_SW")
private String buyItemSw;
@Column(name = "CENT_OFF_SW")
private String centOffSw;
@Column(name = "DEPT_ID")
private Integer deptId;
...

CompositeUpcCompositeId
...
private Integer coupId;
private BigDecimal retailUnitGtin;

public CouponUpcCompositeId(Integer coupId, BigDecimal retailUnitGtin) {
super();
this.coupId = coupId;
this.retailUnitGtin = retailUnitGtin;
}
...

Code executed(JUnit)
public void testUpdate() {
try {

dummyCouponCreate2 = couponService.getCoupon(1);

Upc prod = dummyCouponCreate2.getProducts().iterator().next();

prod.setId(null);
dummyCouponCreate2.getProducts().remove(prod);

Coupon result = couponService.update(dummyCouponCreate2);
if (result != null) {
assertTrue(true);
} else {
fail("Error: Coupon is null");
}
} catch (ServiceLookUpException e) {
e.printStackTrace();
fail("Error:" + e.getMessage());
}
}


Service Implementation
@Transactional
public Coupon update(Coupon coupon) throws ServiceLookUpException {
Coupon result = null;
try {
result = getJpaTemplate().merge(coupon);
getJpaTemplate().flush();
} catch (DataAccessException e) {
throw new ServiceLookUpException(e);
}
return result;
}

Code between sessionFactory.openSession() and session.close():
Using JPA Template, no session.

Name and version of the database you are using:

...
Hibernate: update dbo.COUP_UPC set COUP_ID=null where COUP_ID=? and COUP_ID=? and RETL_UNTI_GTIN=?

Problems with Session and transaction handling?
No

Hi there,

in case you come back after some months:

you configured bidirectional mapping, i.e. references between the 2 Entities exist on both sides.
So for deletion you should null or remove data at both sides, preferable in a Helper method (on 1-side) like

public void removeChild(Child child) {
...
children.remove(child);
/***** that's missing in your code */
child.setParent(null);
/*****/
}

Same when adding children.

Have fun, Chris
