Jira issue originally created by user jeffreiffers:

The creation of an Associated Collection of a Proxy Class is broken by this line:

$reflField->getValue($entity) ?: new ArrayCollection

$entity is a Proxy Class and the property is the field users. The function ReflectionProperty::getValue() will return an Entity User. This results that the internal collection of the PersistenCollection is an Entity. This results in:

Fatal error: Call to undefined method Entity\User::clear() in \library\Doctrine\ORM\PersistentCollection.php on line 206

This is my Entity Configuration

class Organization {
    /****
     * @OneToMany(targetEntity="User", mappedBy="organization", cascade={"persist", "remove"})
     */
    private $users;    

    public function **constructor() {
      $this->users = new ArrayCollection();
   }
}

class User {
    /****
     * @ManyToOne(targetEntity="Organization", inversedBy="users")
     * @JoinColumn(name="organization_id", referencedColumnName="id")
     */ 
    private $organization;  
}

I don't understand why this $reflField->getValue() returns a user entity. It should only return either NULL or a collection.
