Multiple @Valid annotations failing

JamesWoodward · **Posted:** Wed Apr 28, 2010 11:35 am

Hi,

I have a J2SE (JPA) project running fine under Hibernate 3.3.2.GA, Hibernate Annotation 3.4.0.GA, Hibernate Entity Manager 3.4.0.GA & Hibernate Validator 3.1.0.GA.

I have recently upgraded the project to use Hibernate Core 3.5.1.Final (JPA2), Hibernate Validator 4.0.2 (Bean Validation 2.0).

I have made all the package import & annotation changes but am seeing a problem when I have multiple embbeded fields in an entity class, as follows:

Code:

@Entity
class Order implements Serializable {

    @Embedded
    @AssociationOverrides({
        @AssociationOverride(name="country.id", joinColumns={@JoinColumn(name="SENDER_COUNTRY")}),
    })
    @AttributeOverrides({
        @AttributeOverride(name="addressLine1", column=@Column(name="SENDER_ADDRESS_LINE_1")),
        @AttributeOverride(name="addressLine2", column=@Column(name="SENDER_ADDRESS_LINE_2")),
        @AttributeOverride(name="addressLine3", column=@Column(name="SENDER_ADDRESS_LINE_3")),
        @AttributeOverride(name="town", column=@Column(name="SENDER_TOWN")),
        @AttributeOverride(name="county", column=@Column(name="SENDER_COUNTY")),
        @AttributeOverride(name="postcode", column=@Column(name="SENDER_POSTCODE")),
    })
    @Valid
    private Address sender;

    @Embedded
    @AssociationOverrides({
        @AssociationOverride(name="country.id", joinColumns={@JoinColumn(name="RECIPIENT_COUNTRY")}),
    })
    @AttributeOverrides({
        @AttributeOverride(name="addressLine1", column=@Column(name="RECIPIENT_ADDRESS_LINE_1")),
        @AttributeOverride(name="addressLine2", column=@Column(name="RECIPIENT_ADDRESS_LINE_2")),
        @AttributeOverride(name="addressLine3", column=@Column(name="RECIPIENT_ADDRESS_LINE_3")),
        @AttributeOverride(name="town", column=@Column(name="RECIPIENT_TOWN")),
        @AttributeOverride(name="county", column=@Column(name="RECIPIENT_COUNTY")),
        @AttributeOverride(name="postcode", column=@Column(name="RECIPIENT_POSTCODE")),
    })
    @Valid
    private Address recipient;
}

When I attempt to validate this entity using:

Code:

...
    Validator validator = Validation.buildDefaultValidatorFactory().getValidator();
    Set<ConstraintViolation<Order>> constraintViolations = validator.validate(order);
...    

I get an error complaining that

Code:

   at org.hibernate.validator.engine.ValidatorImpl.isValidationRequired(ValidatorImpl.java:764)
   ... 17 more

If I remove one of the @Valid annotations the other one works fine, but I only get one address validated!

Many Thanks,
James

Hi James,

I tried a similar usecase within Hibernate Core + Validator (Order instance with two embedded entities) and it worked fine. Are you still having this problem? If so it would help if you would post your complete mappings (including Address and Country) and the session code triggering the exception.

I am a little surprised about about "Unable to find field or method: class test.model.Address#address". For some reason Validator seems to think the Address class contains a field 'address'. Does it?
