[hibernate-issues] [Hibernate-JIRA] Commented: (BVAL-234) Ignore @NotNull on JPA's @GeneratedValue properties for pre-persist operations

[David Konecny (JIRA)]

David Konecny commented on BVAL-234:
------------------------------------

FYI: I commented in NetBeans issue why I think this should be resolved on JPA side - http://netbeans.org/bugzilla/show_bug.cgi?id=197845#c3
It is possible I'm completely wrong here as spec is not very clear to me. Until we reach a consensus I suggest NetBeans do not generate @NotNull constraint as it is causing more harm than help.

>             Project: Bean Validation
>          Issue Type: Improvement
>          Components: spec-general
>    Affects Versions: 1.1
>         Environment: Netbeans 7, Seam 3 under JBOSS AS 7
>            Reporter: Richard Clarke
>            Priority: Minor
>              Labels: bean, validation
>   Original Estimate: 8h
>  Remaining Estimate: 8h
>
> When using NetBeans 7 to generate entity classes from a database table, the entity classes are generated with the following annotations...
> public class Orders implements Serializable {
>     private static final long serialVersionUID = 1L;
>     @Id
>     @GeneratedValue(strategy = GenerationType.IDENTITY)
>     @Basic(optional = false)
>     @NotNull
>     @Column(name = "orderid")
>     private Integer orderid;
> .....
> When persisting, bean validation fails because the autogenerated primary key is null at the time the object is persisted.
> Netbeans have stated that they wont fix this as they see it as bean validation issue rather than their generated classes.
