overriding template of password change fos user bundle - symfony

Question

HI everyone Im working on a project using FOSUserBundle to manage users inside the application, what I want to do is to - almost the same thing as - move/copy the template of password change inside a page that contains the profile of the current user, it works fine, it displays for me ChangePasswordFormType, however when I submit the changes to the controller it gives me an error like this :
Catchable Fatal Error: Argument 1 passed to User\UserBundle\Entity\Acces::checkAllFields() must be an instance of Symfony\Component\Validator\ExecutionContext, instance of Symfony\Component\Validator\Context\ExecutionContext given
thats my controller :
$request = $this->get('request');
$em = $this->getDoctrine()->getManager();
$roles = $em->getRepository('AdminAdminBundle:Role')->findAll();
$userManager = $this->get('fos_user.user_manager');
$user = new \User\UserBundle\Entity\Acces();
$user = $this->container->get('security.context')->getToken()->getUser();
/** #var $dispatcher \Symfony\Component\EventDispatcher\EventDispatcherInterface */
$dispatcher = $this->container->get('event_dispatcher');
$event = new GetResponseUserEvent($user, $request);
$dispatcher->dispatch(FOSUserEvents::CHANGE_PASSWORD_INITIALIZE, $event);
if (null !== $event->getResponse()) {
return $event->getResponse();
}
/** #var $formFactory \FOS\UserBundle\Form\Factory\FactoryInterface */
$formFactory = $this->container->get('fos_user.change_password.form.factory');
$form = $formFactory->createForm();
$form->setData($user);
$currentuser = $user;
$personnel = $em->getRepository('AdminAdminBundle:Personnel')->findBy(array('acces' => $user));
$user = $this->container->get('security.context')->getToken()->getUser();
if (!is_object($user) || !$user instanceof UserInterface) {
throw new AccessDeniedException('Cet utilisateur n\'a pas d\'acces à ce contenu.');
}
if ($request->isMethod('POST')) {
/** #var $formFactory \FOS\UserBundle\Form\Factory\FactoryInterface */
$formFactory = $this->get('fos_user.change_password.form.factory');
$form = $formFactory->createForm();
$form->setData($user);
$form->handleRequest($request);
if ($form->isValid()) {
/** #var $userManager \FOS\UserBundle\Model\UserManagerInterface */
$userManager = $this->container->get('fos_user.user_manager');
$event = new FormEvent($form, $request);
$dispatcher->dispatch(FOSUserEvents::CHANGE_PASSWORD_SUCCESS, $event);
$userManager->updateUser($user);
if (null === $response = $event->getResponse()) {
$url = $this->container->get('router')->generate('personnel_profile');
$response = new RedirectResponse($url);
}
$dispatcher->dispatch(FOSUserEvents::CHANGE_PASSWORD_COMPLETED, new FilterUserResponseEvent($user, $request, $response));
return $response;
}
}
The View code is :
<form role="form" name="passchange" method="post" {{ form_enctype(password_form) }} action="{{ path('personnel_update_personnal') }}" id="form_sample_2">
<input type="hidden" name="passchange" value="0" />
<div class="form-group">
<label class="control-label">Mot de passe actuel</label>
{{ form_widget(password_form.current_password,{ 'attr': {'required': 'required', 'class':'form-control'} }) }}
<span class="help-block">
{{ form_errors(password_form.current_password) }} </span>
</div>
<div class="form-group">
<label class="control-label">Nouveau mot de passe</label>
{{ form_widget(password_form.plainPassword.first,{ 'attr': {'required': 'required', 'class':'form-control'} }) }}
<span class="help-block">
{{ form_errors(password_form.plainPassword.first) }} </span>
</div>
<div class="form-group">
<label class="control-label">Confirmation mot de passe</label>
{{ form_widget(password_form.plainPassword.second,{ 'attr': {'required': 'required', 'class':'form-control'} }) }}
<span class="help-block">
{{ form_errors(password_form.plainPassword.second) }} </span>
</div>
<div class="margin-top-10">
<button type="submit" class="btn green-haze">Valider le changement</button>
<button type="reset" class="btn default reset">Annuler le changement</button>
</div>
</form>
A simple note: The entity User (of the userBundle) in my case is named Acces
The error given above is generated on the line : $form->handleRequest($request);
Plz if someone has encountered this error, any info could be helpful
Thanks a lot.
Edit : the Use Entity :
