Question

I have a simple class constraint validator which is referenced correctly in my entity and I can see that it is being called and returning false when I validate my form based on the entity, but $form->isValid() is returning true.

Any idea why this is happening? Surely any constraint returning false should cause the form to be invalid?

Entity:

* @ACMEAssert\ExampleConstraint()

ACMEConstraint:

**
 * @Annotation
 */
class ExampleConstraint extends Constraint
{
    public function validatedBy()
    {
        return 'acme.example.validator.example';
    }

    public function getTargets()
    {
        return Constraint::CLASS_CONSTRAINT;
    }
}

ACMEValidator:

class ExampleValidator extends ConstraintValidator
{
    public function isValid($entity, Constraint $constraint)
    {
        return false;
    }
}

Try this: Set an error message (Violation):

$this->context->addViolation('bar', array(), null);
