"This form should not contain extra fields" on step 1 (Symfony2.1)

[stevelacey]

I'm getting this error constantly, and having tried disabling CSRF protection and removing all of my more complicated FormType's, I'm at somewhat of a loss as to what is causing the problem.

Note: I tried removing the event listener, no change.

My FormType looks something like this:

public function buildForm(FormBuilderInterface $builder, array $options)
{
    switch ($options['flowStep']) {
        case 1:

            $builder->addEventListener(FormEvents::PRE_SET_DATA, function($event) use ($builder) {
                $form = $event->getForm();
                $review = $event->getData();

                $factory = $builder->getFormFactory();

                if (!$review->getDealership()) {
                    $field = $factory->createNamed('dealership', 'dealership');
                } else {
                    $field = $factory->createNamed('dealership', 'hidden', $review->getDealership()->getId());
                }

                $form->add($field);
            });

            $builder->add('ratings', 'collection', array(
                'type' => new Rating,
            ));

            $builder->add('comments');

            break;

        case 2:

            $builder->add('department', 'department');

            // $builder->add('employees');

            $builder->add('visited', null, array(
                'label' => 'Date of visited to dealership',
                'format' => 'dd-MM-yyyy',
                'years' => range(date('Y'), date('Y') - 2)
            ));;

            break;
    }
}

public function setDefaultOptions(OptionsResolverInterface $resolver)
{
    $resolver->setDefaults(array(
        'data_class' => 'ACMEDemo\ReviewBundle\Entity\Review',
        'flowStep' => 1
    ));
}

and my template features:

{% include 'CraueFormFlowBundle:FormFlow:stepField.html.twig' %}

Any thoughts on what the problem might be?

Also, when first loading the form, getCurrentStep returns null and I get a blank form, I have to click next to get to step 1, despite my setDefaultOptions looking like:

    $resolver->setDefaults(array(
        'data_class' => 'ACMEDemo\ReviewBundle\Entity\Review',
        'flowStep' => 1
    ));

Any ideas?

Turned out I wasn't binding the data before creating the form, basic fail.

$this->flow->bind($review);

Thanks!
