• The methods setMessage(), getMessageTemplate() and getMessageParameters() in the ConstraintValidator class were deprecated and will be removed in Symfony 2.3.

  If you have implemented custom validators, you should use the addViolation() method on the ExecutionContext object instead.

  Before:

  public function isValid($value, Constraint $constraint)
  {
    // ...
    if (!$valid) {
        $this->setMessage($constraint->message, array(
            '{{ value }}' => $value,
        ));
  
        return false;
    }
  }

  After:

  public function isValid($value, Constraint $constraint)
  {
    // ...
    if (!$valid) {
        $this->context->addViolation($constraint->message, array(
            '{{ value }}' => $value,
        ));
  
        return false;
    }
  }
