And when I attempt to view the form itself, I get the following error message from an UnexpectedTypeException:
Expected argument of type "string or Symfony\Component\Form\FormTypeInterface", "MajorProductions\SewingDiva\SiteBundle\Entity\GalleryThumbnailImage" given
So, it's choking on the FormBuilder addition of my GalleryThumbnailImage field, thinking it should be backed by a string rather than that object. I really don't know why it's doing that, however. Could it be because I used namespace aliases in GalleryImage (Thumb in place of GalleryThumbnailImage and Full in place of GalleryFullSizeImage)? Or am I missing something obvious?
EDIT: The problem remains even after creating form types for GalleryFullSizeImage and GalleryThumbnailImage:
namespace MajorProductions\SewingDiva\SiteBundle\Form\Type;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolverInterface;
class GalleryFullSizeImageType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder->add('file', 'file');
}
public function getName()
{
return 'galleryFullSizeImage';
}
public function setDefaultOptions(OptionsResolverInterface $resolver)
{
$resolver->setDefaults(array('data_class' => 'MajorProductions\SewingDiva\SiteBundle\Entity\GalleryFullSizeImage'));
}
}

}
Note that where // ---- is written in my code, that represents the end of one file and the beginning of another. Given the length of my entity code with all of the Doctrine annotations, I figured I'd save some vertical space by putting the code of individual classes in the same code blocks here.
