[TYPO3-dev] M:M relation objects not initialized

[Kevin von Spiczak]

Hi guys,

I'm currently learning extbase development. My extension has a class person and a class role. I have a Person-Role-Relationship class which should be holding all the roles related to a person. When I debug the relation in the frontend the person and role objects are NULL. I think it is some naming convention problem or something like that.
Here are my classes:
<?php
namespace Vendor\People\Domain\Model;
/**
 * Class Person
 * @scope prototype
 * @entity
 * @package Vendor\People\Domain\Model
 */
class Person extends \TYPO3\CMS\Extbase\DomainObject\AbstractEntity {

    public function __construct() {
        $this->initStorageObjects();
    }

    /**
     * @return void
     */
    protected function initStorageObjects() {
        $this->roles = new \TYPO3\CMS\Extbase\Persistence\ObjectStorage();
    }
    /**
     * Roles
     * @var \TYPO3\CMS\Extbase\Persistence\ObjectStorage<\Vendor\People\Domain\Model\PersonRelation>
     */
    protected $roles = NULL;

    /**
     * the person's first name
     * @var string
     * @validate StringLength(minimum = 3, maximum = 50)
     */
    protected $firstname;

    /**
     * the person's last name
     * @var string
     * @validate StringLength(minimum = 3, maximum = 50)
     */
    protected $lastname;

    /**
     * the person's responsibilities within the company
     * @var string
     */
    protected $role;

    /**
     * Photo
     * @var \TYPO3\CMS\Extbase\Domain\Model\FileReference
     */
    protected $photo;

    /**

     */

    /**
