Phalcon 2.0.0 View Documentation wrong

In the Section Simple Rendering in the Section "Using Views" of the Phalcon 2.0.0 Documentation is this Code Example:

<?php

use Phalcon\Mvc\Controller;

class PostsController extends \Controller
{

    public function indexAction()
    {
        //Render 'views-dir/index.phtml'
        echo $this->view->render('index');

        //Render 'views-dir/posts/show.phtml'
        echo $this->view->render('posts/show');

        //Render 'views-dir/index.phtml' passing variables
        echo $this->view->render('index', array('posts' => Posts::find()));

        //Render 'views-dir/posts/show.phtml' passing variables
        echo $this->view->render('posts/show', array('posts' => Posts::find()));
    }

}

But thats wrong. I can't simply pass a string like in the first and second example.

This method Documentation looks like this:

    /**
     * Executes render process from dispatching data
     * <code>
     * //Shows recent posts view (app/views/posts/recent.phtml)
     * $view->start()->render('posts', 'recent')->finish();
     * </code>
     *
     * @param string $controllerName 
     * @param string $actionName 
     * @param array $params 
     * @return \Phalcon\Mvc\View 
     */
    public function render($controllerName, $actionName, $params = null) {}

So either the Method is wrong in Phalcon v2.0.0 or the Documentation is wrong and should be updated.

Which is wrong? The Documentation or is it a Bug in Phalcon v2.0.0?
