Problems with unique constraint

[KSDaemon]

Hi! I faced a problem with unique constraint check.
In User model:

    attributes: {
        login: {
            type              : 'string',
            size              : 64,
            unique            : true,
            notEmpty          : true,
            alphanumericdashed: true
        }

Then in controller action (passing a login, that allready exists in table in db):

        User.create(req.params.all())
            .exec(function (err, user) {
               ...
             });

Doesn't get to exec callback function with errors:
