Doctrine 2: OneToMany Relation, order by foreign key - symfony

Question

I have three entities (Profile, ProfileValue and Value).
A Profile has a one-to-many relation with ProfileValue, which has a many-to-one relation with the Value entity.
Is it possible to get the rleated ProfileValues from the Profile, ordered by the value id?
If I add the orderby annotation for a non-foreign-key like the enabled field in ProfileValue, it works. But for a foreign key, it failed with the message "inrecognized field". Any ideas?
/**
*
* #ORM\Table(name="profile")
* #ORM\Entity
*/
class Profile {
/**
* #var integer $id
*
* #ORM\Column(name="id", type="integer", nullable=false, options={"unsigned"=true})
* #ORM\Id
* #ORM\GeneratedValue(strategy="IDENTITY")
*/
private $id;
/**
* #var array $profileCValues
* #ORM\OneToMany(targetEntity="ABC\XYZBundle\Entity\ProfileValue", mappedBy="profile", cascade={"persist"})
* #ORM\OrderBy({"value" = "ASC"})
*/
private $profileValues;
And here is the ProfileValue entity:
/**
* ABC\XYZBundle\Entity\ProfileValue
*
* #ORM\Table(name="profile_value", indexes={#ORM\Index(columns={"profile_id"}), #ORM\Index(columns={"value_id"}) })
* #ORM\Entity
*/
class ProfileValue {
/**
* #var integer $id
*
* #ORM\Column(name="id", type="integer", nullable=false, options={"unsigned"=true})
* #ORM\Id
* #ORM\GeneratedValue(strategy="IDENTITY")
*/
private $id;
/**
* #var integer $enabled
*
* #ORM\Column(name="enabled", type="boolean", length=1, nullable=true)
*/
private $enabled;
/**
* #var ABC\XYZBundle\Entity\Profile
* #ORM\ManyToOne(targetEntity="ABC\XYZBundle\Entity\Profile", inversedBy="profileValues")
* #ORM\JoinColumn(name="profile_id", referencedColumnName="id", nullable=true, onDelete="CASCADE")
*/
private $profile;
/**
* #var ABC\XYZBundle\Entity\Value
* #ORM\ManyToOne(targetEntity="ABC\XYZBundle\Entity\Value")
* #ORM\JoinColumn(name="value_id", referencedColumnName="id", onDelete="CASCADE")
*/
private $value;
}

Answer 1

Had the same problem and solved it by adding a new field with foreign key:
/**
* #var integer $valueId
*
* #ORM\Column(name="value_id", type="integer")
*/
private $valueId;
Then you can order it without problems:
/**
* #var array $profileCValues
* #ORM\OneToMany(targetEntity="ABC\XYZBundle\Entity\ProfileValue", mappedBy="profile", cascade={"persist"})
* #ORM\OrderBy({"valueId" = "ASC"})
*/
private $profileValues;

Answer 2

Does this work?
/**
* #var array $profileCValues
* #ORM\OneToMany(targetEntity="ABC\XYZBundle\Entity\ProfileValue", mappedBy="profile", cascade={"persist"})
* #ORM\OrderBy({"id" = "ASC"})
*/
private $profileValues;
I don't use XML but this works in YML:
oneToMany:
foos:
targetEntity: Company\ProjectBundle\Entity\Foo
mappedBy: bar
orderBy: { 'id': ASC }
