Symfony: using $this->widgetSchema->setFormFormatterName('list')

Question

Hi,

im using $this->widgetSchema->setFormFormatterName('list'); this way below to render my form as a list but it is still a table. Any idea?

public function configure()
  {

            parent::configure();

            $this->widgetSchema->setFormFormatterName('list');

  }

}

Any idea?
