I've created a new module named event_extended, which depends on the module named event. In my module, I've created a class ee.diploma. I created a new menu option to access to the views of this projects:

<menuitem name="Diplomas"
            id="menu_action_event_diploma" parent="base.menu_event_main"
            action="action_event_diploma" sequence="11"
            groups="event.group_event_manager,event.group_event_user"/>

As you can see, I've set some groups to the menuitem: I copied them from other existing menuitem which was set on the event module code. I did this because I want my menu option to bevahe like that menuitem.

As I want to use the same user groups as the ones declared in the module event, I didn't create any XML file in the security folder. I've only created a CSV file (which I've included in the array data of __openerp__.py). This is my CSV:

id, name, model_id:id, group_id:id, perm_read, perm_write, perm_create, perm_unlink

access_ee_diploma, ee.diploma, model_ee_diploma, event.group_event_user, 1, 1, 1, 1

The problem is: I can't see the menu option if I'm logged as a normal user (it doesn't mind if my user belongs to event.group_event_manager or event.group_event_user).

Can anyone help me, please? I've seen several questions which ask the same as I do, and I've tried their answers with no result. There must be something I'm missing.

EDIT

The rows I write in my CSV are being ignored. I have the next structure in my module

event_extended
|_ controllers
|_ i18n
|_ report
|_ security
|_ static
|_ wizard
|_ __openerp__.py
... etc

And my __openerp__.py is:
