Symfony2 Doctrine Extensions generating entities from YML - symfony

Question

I am trying to use the Timestampable behaviour from Doctrine Extensions, I installed StofDoctrineExtensionsBundle to help me with that. But when I make my YML scheme and run the generate entities command, everything runs without errors, but in the generated php class no Gedmo/DoctrineExtensions annotations appear. What am I doing wrong?
This is the YML file I use for the simple issue tracker I want to make (Issue.orm.yml):
Theta\IssueTrackerBundle\Entity\Issue:
type: entity
table: issues
id:
id:
type: integer
generator:
strategy: AUTO
fields:
category:
type: string
length: 16
created_at:
type: datetime
gedmo:
timestampable:
on: create
updated_at:
type: datetime
gedmo:
timestampable:
on: update
closed_at:
type: datetime
gedmo:
timestampable
title:
type: string
length: 64
oneToOne:
user_id:
targetEntity: ThetaUserBundle\User
assigned_to:
targetEntity: ThetaUserBundle\User
This is the generated php class (Issue.php):
namespace Theta\IssueTrackerBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
/**
* Issue
*/
class Issue
{
/**
* #var integer
*/
private $id;
/**
* #var string
*/
private $category;
/**
* #var \DateTime
*/
private $created_at;
/**
* #var \DateTime
*/
private $updated_at;
/**
* #var \DateTime
*/
private $closed_at;
/**
* #var string
*/
private $title;
/**
* #var \ThetaUserBundle\User
*/
private $user_id;
/**
* #var \ThetaUserBundle\User
*/
private $assigned_to;
/**
* Get id
*
* #return integer
*/
public function getId()
{
return $this->id;
}
/**
* Set category
*
* #param string $category
* #return Issue
*/
public function setCategory($category)
{
$this->category = $category;
return $this;
}
/**
* Get category
*
* #return string
*/
public function getCategory()
{
return $this->category;
}
/**
* Set created_at
*
* #param \DateTime $createdAt
* #return Issue
*/
public function setCreatedAt($createdAt)
{
$this->created_at = $createdAt;
return $this;
}
/**
* Get created_at
*
* #return \DateTime
*/
public function getCreatedAt()
{
return $this->created_at;
}
/**
* Set updated_at
*
* #param \DateTime $updatedAt
* #return Issue
*/
public function setUpdatedAt($updatedAt)
{
$this->updated_at = $updatedAt;
return $this;
}
/**
* Get updated_at
*
* #return \DateTime
*/
public function getUpdatedAt()
{
return $this->updated_at;
}
/**
* Set closed_at
*
* #param \DateTime $closedAt
* #return Issue
*/
public function setClosedAt($closedAt)
{
$this->closed_at = $closedAt;
return $this;
}
/**
* Get closed_at
*
* #return \DateTime
*/
public function getClosedAt()
{
return $this->closed_at;
}
/**
* Set title
*
* #param string $title
* #return Issue
*/
public function setTitle($title)
{
$this->title = $title;
return $this;
}
/**
* Get title
*
* #return string
*/
public function getTitle()
{
return $this->title;
}
/**
* Set user_id
*
* #param \ThetaUserBundle\User $userId
* #return Issue
*/
public function setUserId(\ThetaUserBundle\User $userId = null)
{
$this->user_id = $userId;
return $this;
}
/**
* Get user_id
*
* #return \ThetaUserBundle\User
*/
public function getUserId()
{
return $this->user_id;
}
/**
* Set assigned_to
*
* #param \ThetaUserBundle\User $assignedTo
* #return Issue
*/
public function setAssignedTo(\ThetaUserBundle\User $assignedTo = null)
{
$this->assigned_to = $assignedTo;
return $this;
}
/**
* Get assigned_to
*
* #return \ThetaUserBundle\User
*/
public function getAssignedTo()
{
return $this->assigned_to;
}
}
The timestampable behaviour does not appear in the php class, and I don't understand why. I followed the instructions for installing the StofDoctrineExtensionsBundle to the letter, and it seems to be installed correctly, but it doesn't do anything. I am using Symfony 2.2.
So my question: am I expecting something that is not supposed to happen, or am I doing something wrong?
Thanks for your help.

Answer 1

Not sure if its works the same way for StofDoctrineExtensions but generally you would need to put the lifecyccallbacks in your yml.
lifecycleCallbacks:
postPersist: doSomething
# callback # method in entity
And then the annotations and the method name would match this.
