Symfony2 custom validator annotation not working - symfony

Question

I have a custom validator in src/VNN/PressboxBundle/Component/Validator/CurrentPasswordValidator.php:
<?php
namespace VNN\PressboxBundle\Component\Validator\Constraints;
use Symfony\Component\Validator\ConstraintValidator,
Symfony\Component\Validator\Constraint,
Symfony\Component\Security\Core\Encoder\EncoderFactoryInterface,
Symfony\Component\Security\Core\SecurityContextInterface,
JMS\DiExtraBundle\Annotation\Validator,
JMS\DiExtraBundle\Annotation\InjectParams,
JMS\DiExtraBundle\Annotation\Inject;
/**
* #Validator("user.validator.current_password")
*/
class CurrentPasswordValidator extends ConstraintValidator
{
// ...
}
And then I have this at src/VNN/PressboxBundle/Component/Validator/Contraints/CurrentPassword.php:
<?php
namespace VNN\PressboxBundle\Component\Validator\Constraints;
use Symfony\Component\Validator\Constraint;
/**
* #Annotation
*/
class CurrentPassword extends Constraint
{
public $message = "Your current password is not valid";
/**
* #return string
*/
public function validatedBy()
{
return 'user.validator.current_password';
}
}
For some reason, when I try to add an annotation that uses this validator, I get an error. Here's my entity/annotation:
<?php
namespace VNN\PressboxBundle\Entity;
use Symfony\Component\Security\Core\User\UserInterface;
use Doctrine\ORM\Mapping as ORM;
use Doctrine\ORM\Mapping\JoinTable as JoinTable;
use Doctrine\ORM\Mapping\JoinColumn as JoinColumn;
use Symfony\Component\Validator\Constraints as Assert;
use Symfony\Component\Validator\ExecutionContext;
use Symfony\Component\Validator\Mapping\ClassMetadata;
use Symfony\Component\Validator\Constraints\NotBlank;
use Symfony\Component\Validator\Constraints\MaxLength;
use Symfony\Component\Validator\Constraints\Email;
use VNN\PressboxBundle\Component\Validator\Constraints\CurrentPassword;
use Symfony\Bridge\Doctrine\Validator\Constraints\UniqueEntity;
/**
* VNN\PressboxBundle\Entity\User
*
* #ORM\Table(name="user")
* #ORM\Entity
*/
class User implements UserInterface, \Serializable
{
/**
* #var string $password
* #Assert\NotBlank()
* #CurrentPassword()
*
* #ORM\Column(name="password", type="string", length=255)
*/
private $password;
}
The error I'm getting is:
AnnotationException: [Semantical Error] The annotation
"#VNN\PressboxBundle\Component\Validator\Constraints\CurrentPassword"
in property VNN\PressboxBundle\Entity\User::$password does not exist,
or could not be auto-loaded.
What am I doing wrong?

Check that VNN\PressboxBundle\VNNPressboxBundle() is correctly registered with the kernel in AppKernel.php.
Update: If it is correctly registered, and src/ is registered as a fallback with the autoloader (assuming VNN/ is under src/), you may want to try and load the service yourself manually and check the stack trace if/when it fails:
$validator = $container->get('user.validator.current_password');
// Pretending this is a unit test:
// $this->assertInstanceOf('VNN\PressboxBundle\Component\Validator\Constraints\CurrentPasswordValidator', $validator);
Also, make sure you have cleared the cache (if not testing in dev environment).
Side note (but unrelated to your problem) - if you start to add more validators, it will be more useful to use this syntax:
<?php
namespace VNN\PressboxBundle\Entity;
use VNN\PressboxBundle\Component\Validator\Constraints as VNN;
class User implements UserInterface, \Serializable
{
/**
* #VNN\CurrentPassword
*/
private $password;
}
