Conditional Validation

In italy we have a code, called Codice Fiscale, which is for person and corporate.
For person can be 16 and for corporate can be 11.
I think can be useful a condition annotation like @OR(@Lenght(11),@Length(16)).

Any suggestion, for avoiding custom "validator"

Hi Luca,

there is something related in HV 4.2 (currently released as Beta version) which might help you. There you can create composed constraints which's base constraints are joined by a logical OR:

Code:

@ConstraintComposition(OR)
@Size(min = 11, max = 11)
@Size(min = 16, max = 16)
@ReportAsSingleViolation
@Target({ METHOD, FIELD })
@Retention(RUNTIME)
@Constraint(validatedBy = { })
public @interface CodiceFiscale {
   String message() default "codicefiscale.errorkey";
   Class<?>[] groups() default { };
   Class<? extends Payload>[] payload() default { };
}

That said you might consider to model person and corporate with separate classes and annotate each code fiscale member with the appropriate size constraint.

Hth,

Gunnar
