empty response array with unmapped entity

[remoteclient]

Hey there,
I want to expose the symfony security role hierarchy to the client. The route should be /api/role_hierarchy. When the client gets the hierarchy, it can select one or more roles and assign them to one user.

The get started my goal is to expose a static array first and if this works, replace the static array with a appropriate function.

My api_resources.xml (relevant part is on the end):

My Entity:

<?php

namespace MWS\UserBundle\Model;

class RolesHierarchy
{
    private $id;

    private $roles;

    /**
     * @return integer
     */
    public function getId()
    {
        return 1;
    }

    /**
     * @return array
     */
    public function getRoles()
    {
        $this->roles = array(0=>array(0=>'string'), 1=>34);
        return $this->roles;
    }

}

And the entity xml file:

<?xml version="1.0" encoding="UTF-8"?>
<doctrine-mapping xmlns="http://doctrine-project.org/schemas/orm/doctrine-mapping"
                  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
                  xsi:schemaLocation="http://doctrine-project.org/schemas/orm/doctrine-mapping
                                      http://doctrine-project.org/schemas/orm/doctrine-mapping.xsd">

    <entity name="MWS\UserBundle\Model\RolesHierarchy">

        <field name="id" type="integer" />

        <field name="roles" type="array" />

    </entity>

</doctrine-mapping>

When I try to get the result via swagger-ui I always get an empty array as result:

{
  "@context": "/api/contexts/RolesHierarchy",
  "@id": "/api/roles_hierarchy",
  "@type": "hydra:Collection",
  "hydra:member": [],
  "hydra:totalItems": 0
}

Does anybody know how to get unmapped entities working?
