If I use the "Phalcon\Config\Adapter\Yaml" class from the incubator as described in the readme:

    define('APPROOT', dirname(__DIR__));
    define('CONFKEY', 'secret');

    $config = new Phalcon\Config\Adapter\Yaml('path/config.yml', array(
        '!decrypt' => function($value) {
            return (new Phalcon\Crypt)->setCipher('blowfish')->decryptBase64($value, CONFKEY);
        },
        '!approot' => function($value) {
            return APPROOT . $value;
        }
    ));

    echo $config->phalcon->controllersDir;
    echo $config->database->username;
    echo $config->database->password;

I am getting an error: 

BadMethodCallException: Wrong number of parameters

Stack trace:

#0 Phalcon\Config\Adapter\Yaml->__construct(/usr/share/nginx/phalcon-services/config/config.yml, Array([!decrypt] => Object(Closure), [!approot] => Object(Closure)))

However, if instead I manually load the yml file in an array $result and then pass it to a Phalcon\Config constructor, everything works (basically, do the same thing that the adapter does in my index.php inside the public folder).

Also, if I dump the callbacks array, it works as well but obviously without having the values processed by the closure functions. I am not sure why I get that exception when I pass the closures to the adapter.

I am using:

PHP Version 5.4.4-14+deb7u14 YAML module 1.1.1 Phalcon 1.3.2

Could someone help me?

Thanks!
