Not able to register a path [#2376183]

Hello guys,

I guess this is a stupid question, but I just don't get this module work.
I implemented hook_js() as it is described in the readme:

  function my_module_js() {
    return array(
      'path' => array(
        'callback'     => 'my_module_somefunction',
        'bootstrap'    => DRUPAL_BOOTSTRAP_SESSION,
        'access callback'  => 'user_is_logged_in',
        'page arguments'  => array(),
        'skip_hook_init' => FALSE,
      ),
    );
  }

  function my_module_somefunction() {
    echo 'test';
  }

But if I call mysite/js/my_module/somefunction, I'll get 'Error 404 Page not found'.
I checked whether the module is installed correctly with echo 'test'; exit; in the js.php file.
That works. Now if I call mysite/js/my_module/somefunction, I just get 'test' displayed.
So, I read through js.php to check what this file does. I realised, that it checks my_module_js (in the example url above) for the 'somefunction' key. Since there is just the 'path' key, JS_MENU_NOT_FOUND is returned. If I change 'path' to 'somefunction' and call mysite/js/my_module/somefunction I get a fatal error:

Call to a member function getDirectoryPath() on a non-object in .../sites/all/modules/print/print_pdf/print_pdf.module on line 70

What do I missing? I guess, that I just forgot a small thing...

I would welcome every advise.

Thanks a lot!
Daniel

Ok I tried a lot, but I guess I got it now. First I removed 'access callback' => 'user_is_logged_in', and checked in the callback, whether the user is logged in. Then I added user module, because I has enabled the overlay module (I guess I skipped this sentence in your readme...). But then I got the fatal error:

Call to undefined function current_path() in .../modules/overlay/overlay.module

Therefore, I tried to add 'file' => 'includes/path.inc', to my_module_js(), but that did not solve the problem. Since I want the maximum performence anyway, I decided to disable the overlay module, what results in this tiny hook_js():

  function my_module_js() {
    return array(
      'somefunction' => array(
        'callback' => 'my_module_somefunction',
        'bootstrap' => DRUPAL_BOOTSTRAP_SESSION,
       ),
    );
  }

This works and reduces the time for my Ajax requests from 420ms to 55ms! Great job guys!

But I would like to know what I did wrong as long as the overlay module is enabled. My my_module_js() looks like this then:

  function my_module_js() {
    return array(
      'somefunction' => array(
        'callback' => 'my_module_somefunction',
        'dependencies' => array('user'),
        'bootstrap' => DRUPAL_BOOTSTRAP_SESSION,
        'file' => 'includes/path.inc',
       ),
    );
  }

Thanks!
