Symfony 2错误消息

I have a form with a drop down and a set of checkboxes, i've used entity form field type to get the values via DB. it works with one of the entity but not with the other. i have this code seperately inside AddBadgesType there is NO AddBadges entity

<?php
namespace Test\Bundle\TestBundle\Form;

use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;

class AddBadgesType extends AbstractType
{
 /**
  * @param FormBuilderInterface $builder
  * @param array $options
  */
 public function buildForm(FormBuilderInterface $builder, array   $options)
{
    $builder
        ->add('property', 'entity', array(
            'class' => 'TestBundle:Property',
            'property' => 'id',
            'query_builder' => function (\Doctrine\ORM\EntityRepository $er) {
                return $er->createQueryBuilder('property')
                    ->orderBy('property.id ', 'ASC');
            },
        ))
        ->add('badges', 'entity', array(
                'class' => 'TestBundle:Badge',
                'property' => 'name',
                'multiple' => true,
                'expanded' => true,
            ))
        ;
}

/**

 */
public function getName()
{
    return 'test_bundle_testbundle_AddBadges';

However if i change the entity to 'Campus' it works fine, i think it might be something to do with the ManyToMany relationship in property entity?!

Campus entity for reference

    You have not included the Symfony EnityRepository class at the top of your form file so PHP is looking for it in the same directory as your form class. Hence the error message. Add this to your form class (or qualify EntityRepository inline):

    use Doctrine\ORM\EntityRepository;
