[TYPO3-mvc] HowTo output usergroup from fe_user

[Heinz Schilling]

Hi

I tried several tips from the internet but nothing works. I extend fe_user in my Extbase 6.0 / Fluid 6.0 Extension and want to output usergroup.

File: Vendor/Myextension/Classes/Domain/Model/User.php
class User extends \TYPO3\CMS\Extbase\Domain\Model\FrontendUser {
}

File: Vendor/Myextension/Classes/Domain/Repository/UserRepository.php
class UserRepository extends \TYPO3\CMS\Extbase\Persistence\Repository {
}

File: Vendor/Myextension/Classes/Controller/UserController.php
class UserController extends \TYPO3\CMS\Extbase\Mvc\Controller\ActionController {
	/**
	 * userRepository
	 *
	 * @var \Vendor\Myextension\Domain\Repository\UserRepository
	 * @inject
	 */
	protected $userRepository;

	/**
	 * action list
	 *
	 * @return void
	 */
	public function listAction() {
		$users = $this->userRepository->findAll();
		$this->view->assign('users', $users);
	}
}


File: Vendor/Myextension/Configuration/TypoScript/setup.txt
plugin.tx_myextension {
	persistence {
		classes {
			Vendor\Myextension\Domain\Model\User {
				mapping {
					tableName = fe_users
					recordType = Tx_Extbase_Domain_Model_FrontendUser
				}
			}
		}
	}
}

File: Vendor/Myextension/Resources/Private/Templates/User/list.html
<table>
			<f:for each="{users}" as="user">
				<tr>
					<td>{user.username}</td>
					<td>{user.password}</td>
					<td>{user.usergroup.title}</td>
					<td>{user.usergroup.description}</td>
				</tr>
			</f:for>
</table>

Result: 
Works: {user.username}, {user.password}
No output: {user.usergroup.title}, {user.usergroup.description}

What did I miss? I hope, someone can help.

Greetings, Heinz
