I have couple fields within an Entity Class annotated with @NotEmpty Annotation. I am getting Constraint Violation Exception on the field of type List, when persisting the object to database. I have a another field (String) that also has the annotation which does not complain when I comment out the @NotEmpty for List field and saving object. This leads me to think it has something to do with Collections.

Error:
Exception in thread "main" javax.validation.ConstraintViolationException: Validation failed for classes [com.User] during persist time for groups [javax.validation.groups.Default, ]
List of constraint violations:[
ConstraintViolationImpl{interpolatedMessage='may not be empty', propertyPath=tickers, rootBeanClass=class com.User, messageTemplate='{org.hibernate.validator.constraints.NotEmpty.message}'}
]

//Extract of the fields
@Id
@GeneratedValue(strategy=IDENTITY)
@Column(name="id")
private Long id;

@Column(name="name", unique=true)
@Size(max=100)
@NotEmpty
private String name;

@ManyToMany
@JoinTable(name="user_game",
joinColumns = @JoinColumn(name="user_id"),
inverseJoinColumns= @JoinColumn(name="game_id"))
@NotNull
@NotEmpty
private Set<Game> games = new HashSet<Game>();

Version: Hibernate Validator Final 4.3.1.jar

Is this to say that you also get this constraint violation if the games set actually is not empty? Otherwise the violation seems expected to me.

Correct. Constraint Violation is triggered even when games is not empty.

Hum, that's odd indeed. Any chance that you provide me with a minimal test case demonstrating that issue? I could have a look into it then.

Run the AccountTester.class http://filebin.ca/1TAIVraCeIgw.

Hi,

Can you please open a JIRA ticket (https://hibernate.atlassian.net/browse/HV) and attach the test case with sources so I can build/debug myself?

Thanks,

--Gunnar

Done.
