php - Auth token resets after redirect in Silex -

using opauth signup through facebook , twitter, using this example

$app->on(opauthextension::event_success, function ($e) use ($app) {     $userprovider = new userprovider($app);     $userprovider->oauthlogin($e->getsubject()); //stores user , creates session     //echo $app['security']->gettoken(); there works       $e->setargument('result', $app->redirect($app['url_generator']->generate('_homepage'))); }); 

if call $app['security']->gettoken(); works on event dispatcher, after redirect falls down anon. user. login through form forks fine.

the problem in userproviderinterface. refreshuser method serched user wrong field.
