title: Add entity to Symfony2 SonataAdminBundle dashboard
body: <p>I'm trying to integrate <a href="https://github.com/sonata-project/SonataAdminBundle" rel="nofollow">SonataAdminBundle</a> for my Symfony2 project. I extended FOSUserBundle for security and now trying to add users administration.</p>
  
  <p>I installed SonataAdminBundle, set it up (http://symfony2.local/admin/dashboard path works, using <code>sonata.admin.security.handler.noop</code> with the Symfony2 firewall), created UserAdmin class based on <a href="https://github.com/sonata-project/SonataUserBundle" rel="nofollow">SonataUserBundle</a> but nothing appears on dashboard page.</p>
  
  <p>Service configuration is:</p>
  
  <pre><code># src/G/UserBundle/Resources/config/service.yml
  services:
      g.user.form.type.security_roles:
          class: G\UserBundle\Form\Type\SecurityRolesType
          tags:
              - { name: form.type, alias: sonata_security_roles}
          arguments: [Sonata\AdminBundle\Admin\Pool]
  
      g.user.admin.user:
          class: G\UserBundle\Admin\UserAdmin
          tags:
              - { name: sonata.admin, manager_type: orm, group: user, label: user }
          arguments: [null, G\UserBundle\Entity\User, GUserBundle:UserAdmin]
  </code></pre>
  
  <p>I tried getting information from console using <code>php app/console sonata:admin:explain g.user.admin.user</code> - displays all information about administration with the only warning:</p>
  
  <pre><code>Getters constraints
     no getter constraints defined !!
  </code></pre>
  
  <p>So my question is: what could I miss so information about Entity is not appearing on admin dashboard page?</p>
