Emmanuel Bernard commented on ANN-344:
--------------------------------------

yes what I want is an error message between 0 and  20 so basically a validator merge when possible

> When the same validation annotation is applied to an over-riding method in a subclass the expected behaviour is that the validation annotation in the base class is over-ridden.  Currently, both validations are executed.   This severely limits the usability of the package for domain models where inheritance is used.
> The problem also occurs with over-riding interfaces.
> For example:
> class A {
>    @Length (min = 0, max = 32)
>     Integer getFoo() {
>         return foo;
>     }
> }
> class B extends A
> {
>    @Length (min = 15, max = 20)
>     Integer getFoo() {
>         return super.getFoo();
>     }
> }
> In this case validating an instance of class B which has a foo value of 100 will result in two error messages: "foo must be between 15 and 20"  and  "foo must be between 0 and 32".
