Blank page on for some actions

I read source code of pick method. I see that it return $this, so i compare $this->view and $this->view->pick('settings/company'). Diff:

279 -   '_pickView' => null
279 +   protected '_pickView' => 
280 +     array (size=2)
281 +       0 => string 'settings/company' (length=16)
282 +       1 => string 'settings' (length=8)

Ok, probably I know what break views but I have no idea why it works on my dev machine and why doesn't work on production server. In my Routes i have code similar to this: https://github.com/phalcon/cphalcon/issues/284#issuecomment-11723075 which rewrites /controller/some-method to Controller::someMethodAction

// Route for controller action (support dashes in actions)
$router->add("/:controller/:action[/]?", array(
    'namespace' => 'App\Controllers\\',
    'controller' => 1,
    'action' => 2,
))->convert('action', function($action) {
    return Phalcon\Text::camelize($action);
});

// Route for controller action params (support dashes in actions)
$router->add("/:controller/:action/:params[/]?", array(
    'namespace' => 'App\Controllers\\',
    'controller' => 1,
    'action' => 2,
    'params' => 3
))->convert('action', function($action) {
    return Phalcon\Text::camelize($action);
});

This code change $this->view->action to uppercase. For example this url works:

/controller (executes controller/index) 

but this doesn't work:

/controller/index

When I rename /views/controller/index.volt to /views/controller/Index.volt everything is ok. Is possible to use URLs with dashes without renaming views?
