this application works very well .
i compared source codes but i can not found problem.
i use php engine.
my Module class
`
<?php
namespace Frontend;
use Phalcon\Loader,
Phalcon\Mvc\Dispatcher,
Phalcon\Mvc\View,
Phalcon\Mvc\ModuleDefinitionInterface;
class Module implements ModuleDefinitionInterface
{
/**
 * Register a specific autoloader for the module
 */
public function registerAutoloaders()
{
    $loader = new Loader();
    $loader->registerNamespaces(
        array(
            'Frontend\Controllers' => realpath(__DIR__.'/controllers'),
            'Frontend\Models'      => realpath(__DIR__.'/models'),
        )
    );
    $loader->register();
}
/**
 * Register specific services for the module
 */
public function registerServices($di)
{
    //Registering a dispatcher
    $di->set('dispatcher', function() {
        $dispatcher = new Dispatcher();
        $dispatcher->setDefaultNamespace("Frontend\Controllers");
        return $dispatcher;
    });
    //Registering the view component
    $di->set('view', function() {
        $view = new View();
        $view->registerEngines(array(
            ".phtml" => "Phalcon\Mvc\View\Engine\Php",
        ));
        $view->setViewsDir(realpath(__DIR__.'/views/'));
        $view->setLayoutsDir('/layouts/');
        $view->setMainView('index');
        return $view;
    });
}
}
`
is it true settings?
i dont understand what is the problem Because controller is executed and displays strings with 'echo' in action method but does not auto render.
tank you for guidance.
