Overriding GroupAdmin class - php

Question

I try to override my SonataUserBundle GroupAdmin Class, like that :
namespace Application\Sonata\UserBundle\Admin\Model;
use Sonata\AdminBundle\Datagrid\DatagridMapper;
use Sonata\AdminBundle\Datagrid\ListMapper;
use Sonata\AdminBundle\Form\FormMapper;
use Sonata\UserBundle\Admin\Model\GroupAdmin as MyGroupAdmin;
class GroupAdmin extends MyGroupAdmin
{
...
}
And add parameters in my config.yml file :
parameters:
sonata.user.admin.group.class: Application\Sonata\UserBundle\Admin\Model\GroupAdmin
But when I try to view my form I have that exception:
Attempted to load class "GroupAdmin" from namespace "Application\Sonata\UserBundle\Admin\Model".
Did you forget a "use" statement for e.g. "Sonata\UserBundle\Admin\Document\GroupAdmin", "Sonata\UserBundle\Admin\Entity\GroupAdmin" or "Sonata\UserBundle\Admin\Model\GroupAdmin"?
My kernel :
$bundles = array(
new Symfony\Bundle\FrameworkBundle\FrameworkBundle(),
new Symfony\Bundle\SecurityBundle\SecurityBundle(),
new Symfony\Bundle\TwigBundle\TwigBundle(),
new Symfony\Bundle\MonologBundle\MonologBundle(),
new Symfony\Bundle\SwiftmailerBundle\SwiftmailerBundle(),
new Doctrine\Bundle\DoctrineBundle\DoctrineBundle(),
new Sensio\Bundle\FrameworkExtraBundle\SensioFrameworkExtraBundle(),
new Sonata\CoreBundle\SonataCoreBundle(),
new Sonata\BlockBundle\SonataBlockBundle(),
new Knp\Bundle\MenuBundle\KnpMenuBundle(),
new Sonata\DoctrineORMAdminBundle\SonataDoctrineORMAdminBundle(),
new Sonata\AdminBundle\SonataAdminBundle(),
new AppBundle\AppBundle(),
new Knp\Bundle\MarkdownBundle\KnpMarkdownBundle(),
new Ivory\CKEditorBundle\IvoryCKEditorBundle(),
new Sonata\FormatterBundle\SonataFormatterBundle(),
new Sonata\NewsBundle\SonataNewsBundle(),
new Sonata\MediaBundle\SonataMediaBundle(),
new Sonata\IntlBundle\SonataIntlBundle(),
new Sonata\ClassificationBundle\SonataClassificationBundle(),
new FOS\UserBundle\FOSUserBundle(),
new Sonata\UserBundle\SonataUserBundle('FOSUserBundle'),
new Sonata\EasyExtendsBundle\SonataEasyExtendsBundle(),
new JMS\SerializerBundle\JMSSerializerBundle(),
new Application\Sonata\NewsBundle\ApplicationSonataNewsBundle(),
new Application\Sonata\UserBundle\ApplicationSonataUserBundle(),
new Application\Sonata\MediaBundle\ApplicationSonataMediaBundle(),
new Application\Sonata\ClassificationBundle\ApplicationSonataClassificationBundle(),
);
This is 6:00 and I can't find the error. Plz help

It definitely is not a problem with the class declaration or the error would contain 'The file was found but the class was not in it'.
You most likely have a typo in the name of the file
