Framework: Possible problem with registering Custom Validator Resolver

[spib]

I'm using the docs at http://four.laravel.com/docs/validation under 'Registering A Custom Validator Resolver' but I'm getting an exception thrown

class CustomValidator extends Illuminate\Validation\Validator {
    public function validateFoo($attribute, $value, $parameters)
    {
        return $value == 'foo';
    }
}

In my service provider

Validator::resolver(function($translator, $data, $rules, $messages)
{
    return new CustomValidator($translator, $data, $rules, $messages);
});

But I get the following exception

Error: Call to undefined method Illuminate\Support\Facades\Validator::resolver() in /vagrant/bootstrap/compiled.php line 5299

Paste your service provider.

OK, this is the full provider

<?php

use Illuminate\Support\ServiceProvider;

class PlatformServiceProvider extends ServiceProvider
{

    public function register()
    {
        App::bind('Repositories\IAccountRepository', 'Repositories\AccountRepository');
        App::bind('Repositories\ICampaignRepository', 'Repositories\CampaignRepository');
        App::bind('Repositories\IMailingListImportRepository', 'Repositories\MailingListImportRepository');
        App::bind('Repositories\IMailingListRepository', 'Repositories\MailingListRepository');
        App::bind('Repositories\IPersonRepository', 'Repositories\PersonRepository');
        App::bind('Repositories\IUserRepository', 'Repositories\UserRepository');
        App::bind(
            'S3StorageService',
            function () {
                return new S3StorageService(
                    Config::get('s3.key'),
                    Config::get('s3.secret'),
                    Config::get('s3.bucket')
                );
            }
        );
        App::bind(
            'LMongo\Connection',
            function () {
                return LMongo::connection();
            }
        );

        Route::filter(
            'role',
            function ($group) {
                if (Auth::guest()) {
                    return Redirect::to('login');
                }

                $user = Auth::user();

                if (!isset($user)) {
                    return Redirect::to('login');
                }

                // Only allow super if super
                if ($group == User::$user_type_super && $user->user_type != User::$user_type_super) {
                    return Redirect::to('login');
                }

                // Only allow admin if not user
                if ($group == User::$user_type_admin && $user->user_type == User::$user_type_user) {
                    return Redirect::to('login');
                }
            }
        );

        Request::setTrustedProxies(array('127.0.0.1'));

        $this->app['validation.presence'] = $this->app->share(
            function ($app) {
                return new MongoPresenceVerifier($app['db']);
            }
        );

        Validator::resolver(function($translator, $data, $rules, $messages)
        {
            return new \Services\PlatformValidator($translator, $data, $rules, $messages);
        });
    }

}

Move your Route::filters and the Validator::resolve stuff into the boot
method. Register is strictly for registering / binding. Nothing else
should be done.

Yeah, that fixed it. Thanks for the quick response
