Uploading images using Form Collections and Doctrine in Symfony2

I have been trying to make a Form Collection with file upload in Symfony2 and following this guide

http://symfony.com/doc/master/cookbook/form/form_collections.html

but can't seem to make this part work:

// src/Acme/TaskBundle/Entity/Task.php

// ...

public function setTags(ArrayCollection $tags)
{
foreach ($tags as $tag) {
    $tag->addTask($this);
}

$this->tags = $tags;
}

. Basically, I have a Property Entity and an Image Entity with 1 to many relationship. I already made each of their FormTypes and the Property Entity persist just fine on the other hand Image entity's property_id column always gets NULL, even thought other properties of Image entities get persisted properly.

Here is the Property Entity:

<?php

namespace Mata\MainBundle\Entity;

use Doctrine\ORM\Mapping as ORM;
use Doctrine\Common\Collections\ArrayCollection;

use Mata\MainBundle\Entity\Image;


class Property
{

When you add by_reference => false you are suposed to set the counter entity in the add function.

So your property_id should be persisting correctly in the image changing the addImage function in your propery to:

public function addImage(\Mata\MainBundle\Entity\Image $image)
{
  $this->images[] = $image;

  $image->setProperty($this);

  return $this;
}
