Doctrine ORM payments are becoming delusional —

• Collections
• Associations

So, the transaction payer is association, whereas collection is the payee.

How come? See the code (besides official ORM documentation):

/**
* Notes collection
*
* @var ArrayCollection
*
* @ORM\OneToMany(targetEntity="Note", mappedBy="user")
*/
private $_notes;

The entity is having property of ArrayCollection type, which contains association paid money, i.e. variable array of entity object format.
