Symfony error targeted by Callback constraint is not a valid callable

Question

I have this error. Help please.

I use this instruction http://symfony.com/doc/current/reference/constraints/Callback.html for 3.0 version (i use Symfony 3.0)

My validation.yml

App\Bundle\NameBundle\Entity\Product:
    constraints:
        - Callback: [validate]

Entity

namespace App\Bundle\NameBundle\Entity;

use Doctrine\ORM\Mapping as ORM;
use Symfony\Component\Validator\Context\ExecutionContextInterface;
/**
 * Product
 */
class Product
{
    /**
    * @var integer
     */
    private $id;

    /* ... some code .... */

     public function validate(ExecutionContextInterface $context)
     {
         $context->buildViolation('This name sounds totally fake!')
             ->atPath('firstName')
             ->addViolation();
     }
}

what am I doing wrong?

SOLUTION:

in validation.yml

...
- Callback: validate
...

Where is the actual error? What is going wrong? Where are you trying to apply this? etc. — Jason Roman
