Emmanuel Bernard resolved ANN-514:
----------------------------------

    Resolution: Rejected

There is no need for such a feature, the use case is already supported since bean level validation is supported

> I really like Hibernate Validator. In the absense of this framework, I was going to write something similar.
> But, I see a major limitation. If validation of a field depends on the value of another field in the same object, 
> hibernate validator doesn't have a way to handle this.
> The simplest example is when the validator is used for forms. Forms sometimes have fields like "email" and "retypeEmail". 
> It would be great to be able to write a custom annotation:
>   @Match(property="retypeEmail")
>   public String getEmail(){
>     return email;
>    }
> where, getRetypeEmail() is also available in the same object.
> Another example is where validation of a credit card number, depends on the credit card type
> This feature can be implemented, by exposing the object being validated to the isValid() method. 
> Without changing the signature of this method, the object can be exposed via some kind
> of a ValidationContext object, which is stored as a ThreadLocal variable.
> Please let me know the best work around, until this feature can be implemented.
> Regards,
> Rakesh
