Problem with validation

[Miguel Orbegozo]

Hi all,

I'm recently started a project with vraptor 4.

I have a user suscription that works, but now I'm trying to add validation.

The method in the controller:

public void save(@NotNull @Valid User user) {
        validator.onErrorUsePageOf(this).add();
        userService.insertUser(user);
        result.redirectTo(UserController.class).index(user);
    }

Note that the User is a plain bean (we don't use hibernate or another orm):

public class User implements Serializable {
    private long id;
   
    @NotNull @Size(min=8, max=20)
    private String name;

When I add a valid user all works fine, but with a short name user I have this error:

​Hi Miguel! You need to add the ​META-INF/validation.xml file 

indicating to CDI do not validate methods automatically. You 

can find more info about that at this vraptor's site doc page.

We hope so! Please, feel free asking,

Thanks Rodrigo.

That's the answer.

For the time being I like VRaptor and I feel tha I choose the right framework.

Thanks again for your support and for all the caelum team work.
