Symfony2 multiple embedded forms one to many update foreign key - php

Question

Hello i have a problem with my multiple embedded form (one to many).
One game have many prizes and one prize have many options. When i attemp to save this form get an error message
SQLSTATE[23000]: Integrity constraint violation: 1048 Column 'fk_prize' cannot be null
I have already set in my entity on cascade and in my form type set by_refference false but didnt work. All the other assigned foreign keys works perfectly.
UPDATED :
In controller when i do this form saved successfull. But i want to do this with doctrine. Is it bug in doctrine or something wrong in my code ?
Thanks for your time!
//Hacked code in controller to save the form
$prizes = $data->getPrizes();
foreach ($prizes as $prize) {
$prizeOptions = $prize->getPrizesOptions();
foreach ($prizeOptions as $prizeOption) {
$prizeOption->setPrize($prize);
}
}
$em->persist($data);
$em->flush();
<?php
class Game
{
/**
* #ORM\OneToMany(targetEntity="Prize", mappedBy="game", cascade={"persist"})
*/
protected $prizes;
public function __construct()
{
$this->gameUsers = new ArrayCollection();
$this->prizes = new ArrayCollection();
}
}
?>
<?php
class GameType extends AbstractType
{
/**
* #param FormBuilderInterface $builder
* #param array $options
*/
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('alias', 'text' , [
'label'=>'Name'
])
->add('prizes' ,'collection', array(
'type' => new PrizeType($this->intention),
'allow_add' => true,
'allow_delete' => false,
'prototype' => true,
'by_reference' => false,
'label' => false,
))
->add('save', 'submit', [
'attr' => [
'class' => 'btn btn-primary'
]
]);
}
}
<?php
class Prize
{
/**
* The Game
* #ORM\ManyToOne(targetEntity="Game")
* #ORM\JoinColumn(name="game_id", referencedColumnName="id")
*/
protected $game;
/**
* #ORM\OneToMany(targetEntity="PrizeOptions", mappedBy="prize", cascade={"persist"})
*/
protected $prizes_options;
/**
* Constructor
*/
public function __construct()
{
$this->prizes_options = new \Doctrine\Common\Collections\ArrayCollection();
}
}
class PrizeType extends AbstractType

;
}

Doctrine can handle changes in entities only on "owning" side. That means, you can modify relations only in entity where is defined join column/join table.
