title: Symfony FOSUserBundle Cannot instantiate abstract class FOS\UserBundle\Model\User
body: <p>I have a fresh isntalation of Symfony 2.4 + FOSUserBundle.
  I just configured FOSUserBundle, this guide: <a href="https://github.com/FriendsOfSymfony/FOSUserBundle/blob/master/Resources/doc/index.md" rel="nofollow">https://github.com/FriendsOfSymfony/FOSUserBundle/blob/master/Resources/doc/index.md</a></p>
  
  <p>Now I try to create a new user with the CLI </p>
  
  <pre><code>fos:user:create --super-admin user user@domain.com password1
  </code></pre>
  
  <p>And I get this error</p>
  
  <pre><code>PHP Fatal error:  Cannot instantiate abstract class FOS\UserBundle\Model\User in /var/www/symfony2/vendor/friendsofsymfony/user-bundle/FOS/UserBundle/Model/UserManager.php on line 55
  </code></pre>
  
  <p><strong>config.ylm</strong></p>
  
  <pre><code>...
  fos_user:
      db_driver: propel
      firewall_name: main
      user_class: FOS\UserBundle\Model\User
  ...
  </code></pre>
  
  <p><strong>When access /register I get the same error, but /login seems to work fine (although I cant login, since I have no users)</strong></p>
  
  <p>Any ideas?
  Thanks in advance</p>
  
  <p>EDITS:</p>
  
  <p>new user class:</p>
  
  <pre><code>namespace g9\BoBundle\Model;
  
  use FOS\UserBundle\Model\User as MyUser;
  use FOS\UserBundle\Model\UserInterface;
  use FOS\UserBundle\Model\UserManager;
  
  class User extends MyUser {
      # .. no code here yet
  }
  </code></pre>
  
  <p>When I use CLI to create user I get:</p>
  
  <pre><code>  [InvalidArgumentException]
    This user instance is not supported by the Propel UserManager implementation
  </code></pre>
