[Form] ValidationListener validates only "Default" group

https://github.com/symfony/symfony/blob/2.7/src/Symfony/Component/Form/Extension/Validator/EventListener/ValidationListener.php#L64

// Validate the form in group "Default"
$violations = $this->validator->validate($form);

Is it correct? Because in this example the Custom group never will be validated.

    /**
     * @param FormBuilderInterface $builder
     * @param array $options
     */
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder->add('foo', 'hidden', [
            'constraints' => [
                new NotBlank(),
            ],
            'validation_groups' => [
                Constraint::DEFAULT_GROUP,
            ],
        ]);
        $builder->add('bar', 'hidden' , [
            'constraints' => [
                new NotBlank(),
            ],
            'validation_groups' => [
                'Custom',
            ],
        ]);
    }

    /**
     * @param OptionsResolverInterface $resolver
     */
    public function setDefaultOptions(OptionsResolverInterface $resolver)
    {
        $resolver->setDefaults([
            'validation_groups' => [
                Constraint::DEFAULT_GROUP,
                'Custom',
            ],
        ]);
    }

Yes, it is correct. Validation groups for Form's Data are retrieved into the https://github.com/symfony/symfony/blob/2.7/src/Symfony/Component/Form/Extension/Validator/Constraints/FormValidator.php with FormValidator::getValidationGroups

Look also here

Closing it because this doesn't look like a bug. As @origaminal said, validation groups are indeed taken into account to validate the forms.
