blank page when upgrading from 1.3.4 to 2.0.2 Phalcon (not showing content)

Phalcon system in perfect running 1.3.4, 2.0.2 to upgrade to the views do not show me the form or content of the views. renowned folders "Persons" to "persons", ie you change the lowercase pa and if it shows the content.

there any way to display the content leaving P in uppercase?

however there are two views that are not seen, despite the renowned Lower case, placed them as one example of what I have.

in the routes.

    $router = new \Phalcon\Mvc\Router\Annotations(false);

    //se agregan todos los controladores que tienen annotations de rutas

                       ->andWhere("accion = '".$parts[1]."'")
                       ->execute();

If you, we will change this:

        $personas = Personas::query()
                    ->where('controlador = :n:')
                    ->andWhere('accion = :c:')
                    ->bind(array('n'=> $parts[0],
                                 'c'=> $parts[1]))
                    ->execute();

any idea about the problem raised?

The code is too long to understand the problem, could you please reduce it to the minimum necessary to understand your problem?
