Управление полями перевода в типе формы Symfony, созданном с помощью KnpLabs / DoctrineBehaviors и Transhable.

Я новичок в Symfony и использую версию 2.6

Я хотел создать перевод для моих продуктов, следующих https://github.com/KnpLabs/DoctrineBehaviors#translatable

Я закончил с:

<?php

namespace KhaliBundle\Entity;

use Gedmo\Mapping\Annotation as Gedmo;
use Doctrine\ORM\Mapping as ORM;
use Knp\DoctrineBehaviors\Model as ORMBehaviors;

/**
* Product
*
* @ORM\Table(name="products")
* @ORM\Entity
*/
class Product
{
use ORMBehaviors\Translatable\Translatable;

/**
* @var integer
*
* @ORM\Column(name="id", type="integer")
* @ORM\Id
* @ORM\GeneratedValue(strategy="AUTO")
*/
private $id;

/**
* @var string
*
* @Gedmo\Slug(fields={"name"}, updatable=false)
* @ORM\Column(length=255, unique=true)
*/
private $slug;

/**
* @var integer
*
* @ORM\Column(name="status", type="smallint", length=1)
*/
private $status;

/**
* @ORM\ManyToOne(targetEntity="Category", inversedBy="products")
* @ORM\JoinColumn(name="category_id", referencedColumnName="id")
*/
private $category;

/**
* Get id
*
* @return integer
*/
public function getId()
{
return $this->id;
}

/**
* Set slug
*
* @param string $slug
* @return Product
*/
public function setSlug($slug)
{
$this->slug = $slug;

return $this;
}

/**
* Get slug
*
* @return string
*/
public function getSlug()
{
return $this->slug;
}

/**
* Set status
*
* @param integer $status
* @return Product
*/
public function setStatus($status)
{
$this->status = $status;

return $this;
}

/**
* Get status
*
* @return integer
*/
public function getStatus()
{
return $this->status;
}

/**
* Set category
*
* @param \KhaliBundle\Entity\Category $category
* @return Product
*/
public function setCategory(\KhaliBundle\Entity\Category $category = null)
{
$this->category = $category;

return $this;
}

/**
* Get category
*
* @return \KhaliBundle\Entity\Category
*/
public function getCategory()
{
return $this->category;
}

/**
*
*/
public function __call($method, $arguments)
{
return $this->proxyCurrentLocaleTranslation($method, $arguments);
}
}

и файл ProductTranslation.php

<?php

namespace KhaliBundle\Entity;

use Doctrine\ORM\Mapping as ORM;
use Knp\DoctrineBehaviors\Model as ORMBehaviors;

/**
* @ORM\Table(name="product_translations")
* @ORM\Entity
*/
class ProductTranslation
{
use ORMBehaviors\Translatable\Translation;

/**
* @ORM\Column(type="string", length=255)
*/
private $name;

/**
* @ORM\Column(type="string", length=255)
*/
private $description;

/**
* Set name
*
* @param string $name
* @return ProductTranslation
*/
public function setName($name)
{
$this->name = $name;

return $this;
}

/**
* Get name
*
* @return string
*/
public function getName()
{
return $this->name;
}

/**
* Set description
*
* @param string $description
* @return ProductTranslation
*/
public function setDescription($description)
{
$this->description = $description;

return $this;
}

/**
* Get description
*
* @return string
*/
public function getDescription()
{
return $this->description;
}
}

и ProductType.php

<?php

namespace KhaliBundle\Form;

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

class ProductType extends AbstractType
{
/**
* @param FormBuilderInterface $builder
* @param array $options
*/
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('name')
->add('slug')
->add('status')
->add('category')
;
}

/**
* @param OptionsResolverInterface $resolver
*/
public function setDefaultOptions(OptionsResolverInterface $resolver)
{
$resolver->setDefaults(array(
'data_class' => 'KhaliBundle\Entity\Product'
));
}

/**
* @return string
*/
public function getName()
{
return 'khalibundle_product';
}
}

Но я получил исключение:

Neither the property "name" nor one of the methods "getName()", "name()", "isName()", "hasName()", "__get()" exist and have public access in class "KhaliBundle\Entity\Product".
