Symfony2 + SonataAdmin + VichUploaderBundle - Image Upload Field - php

Question

Spent last days trying, as a newcomer to Symfony find a good solution on integrating a image upload field in an existing Entity in Sonata Admin. I've been Googling and following guides available but unfortunately I cannot figure it out.
Setup as specified in headline
Symfony2
SonataAdmin
VichUploaderBundle
Im currently stuck with the following error:
"Catchable Fatal Error: Argument 1 passed to Beautify\BeautiesBundle\Entity\Beauty::setImageFile() must be an instance of Symfony\Component\HttpFoundation\File\UploadedFile, instance of Symfony\Component\HttpFoundation\File\File given, called in /Users/gmf/symfony/vendor/symfony/symfony/src/Symfony/Component/PropertyAccess/PropertyAccessor.php on line 438 and defined in /Users/gmf/symfony/src/Beautify/BeautiesBundle/Entity/Beauty.php line 75 "
The image upload field renders correctly and I receive the error after submitting.
This is line 75:
/**
* If manually uploading a file (i.e. not using Symfony Form) ensure an instance
* of 'UploadedFile' is injected into this setter to trigger the update. If this
* bundle's configuration parameter 'inject_on_load' is set to 'true' this setter
* must be able to accept an instance of 'File' as the bundle will inject one here
* during Doctrine hydration.
*
* #param File|\Symfony\Component\HttpFoundation\File\UploadedFile
*/
public function setImageFile(UploadedFile $image = null)
{
$this->imageFile = $image;
if ($image) {
// It is required that at least one field changes if you are using doctrine
// otherwise the event listeners won't be called and the file is lost
$this->updatedAt = new \DateTime('now');
}
}

Any help is very appreciated and will make me very happy

Answer 1

You missed the use statement for the File class: use Symfony\Component\HttpFoundation\File\File;

Answer 2

Add the use statement above and then change the method signature to this:
public function setImageFile(File $image = null)
