File update : Argument 1 [...] must be a File

[bonswouar]

While I was going to implement the solution to be able to update Files in an Entity (#8 (comment)), I noticed an Error when I handle my update Form :

Catchable Fatal Error: Argument 1 passed to VENDOR\Bundle\Entity\MyEntity::setImage() must be an instance of Symfony\Component\HttpFoundation\File\File, null given

To fix that I can change that :

public function setImage(File $image)
{
    $this->image = $image;

    return $this;
}

to that :

public function setImageTexte($image)
{
    $this->image = $image;

    return $this;
}

But I guess if that's the solution it would be in the documentation, did I do something wrong ?

By the way, here are my properties :

/**
 * @Vich\UploadableField(mapping="article_image", fileNameProperty="imagePath")
 *
 * Note : This is not a mapped field of entity metadata, just a simple property.
 *
 * @var File $image
 *
 * @Assert\File(maxSize="6000000", mimeTypes={"image/jpeg", "image/png"})
 */
public $image;


/**
 * @var string
 *
 * @ORM\Column(name="image_path", type="string", length=45)
 */
private $imagePath;

Just change your method definition like this:

public function setImage(File $image = null)
