Upload file for each translation - symfony

Question

I have a form with fields that are translated. One of this fields is a file, witch must to be uploaded (each language have different file).
I am using 'stof/doctrine-extensions-bundle' and 'a2lix/translation-form-bundle' and for uploading files 'vich/uploader-bundle' with symfony2.
found this https://github.com/a2lix/TranslationFormBundle/issues/83, but it's not working
Maximum function nesting level of '100' reached, aborting!
My Catalog entity:
/**
* Catalog.
*
* #ORM\Entity()
* #ORM\Table("catalog")
*
* #Vich\Uploadable
*
* #Gedmo\TranslationEntity(class="Entity\Catalog\CatalogTranslation")
*/
class Catalog
{
/**
* #var int
*
* #ORM\Column(type="integer")
* #ORM\Id()
* #ORM\GeneratedValue()
*/
private $id;
/**
* #var string
*
* #ORM\Column()
*
* #Gedmo\Translatable()
*
* #Assert\NotBlank()
*/
private $name;
/**
* #var File
*
* #Vich\UploadableField(mapping="product_image", fileNameProperty="imageName")
*
* #Assert\Image(maxSize = "4M")
*/
protected $imageFile;
/**
* #var string
*
* #ORM\Column(nullable=true)
* #Gedmo\Translatable()
*/
protected $imageName;
/**
* #ORM\OneToMany(
* targetEntity="CatalogTranslation",
* mappedBy="catalog",
* cascade={"persist", "remove"}
* )
*/
private $translations;
}
Also tried this when building form:
->add('imageName', 'a2lix_translationsForms', [
'form_type' => 'vich_file',
'form_options' => array(
'required' => true,
'mapping' => 'product_image',
'allow_delete' => true,
'download_link' => true,
)
])

My guess is that CatalogTranslation should be the class defined as Uploadable as otherwise it will probably confuse VichUploaderBundle.
I'd try something like this:
<?php
/**
* Catalog.
*
* #ORM\Entity()
* #ORM\Table("catalog")
*
* NOT uploadable
*
* #Gedmo\TranslationEntity(class="Entity\Catalog\CatalogTranslation")
*/
class Catalog
{
/**
* #var int
*
* #ORM\Column(type="integer")
* #ORM\Id()
* #ORM\GeneratedValue()
*/
private $id;
/**
* #var string
*
* #ORM\Column()
*
* #Gedmo\Translatable()
*
* #Assert\NotBlank()
*/
private $name;
/**
* #var string
*
* #ORM\Column(nullable=true)
* #Gedmo\Translatable()
*/
protected $imageName;
/**
* #ORM\OneToMany(
* targetEntity="CatalogTranslation",
* mappedBy="catalog",
* cascade={"persist", "remove"}
* )
*/
private $translations;
}
class CatalogTranslation
{
// ... as usual
/**
* #var File
*
* #Vich\UploadableField(mapping="product_image", fileNameProperty="imageName")
*
* #Assert\Image(maxSize = "4M")
*/
protected $imageFile;
protected $imageName;
}
