Mac Osx (Mountain Lion), OrmDesigner2
I created entity "User" with rows: createdat, updatedat and i try to use "lifecycle-callback's" for them.

After export to php files (entity User), he has:
* @ORM\HasLifecycleCallbacks
*/
class User
/**
* @ORM\Column(type="datetime", nullable=false)
*/
private $created_at;
/**
* @ORM\Column(type="datetime", nullable=false)
*/
private $updated_at;
/**
* @ORM\PrePersist
*/
public function setCreatedAt()
{
}
/**
* @ORM\PreUpdate
*/
public function setUpdatedAt()
{
}
As you can see, they without any variables, what i do wrong, or this is bug?
