I have a module already installed inside my project with a couple of new tables. Now, I want to add XML associated with these tables to create menu items.

In my openerp.py, I had this code:

 'data': ['main.xml', 'security/ir.model.access.csv']

Now, I want to add a new file containing my XML:

 'data': ['main.xml', 
          'trips.xml',
          'security/ir.model.access.csv']

trips.xml looks like this:

<openerp>
    <data>

        <record id="action_partner_trip_form" model="ir.actions.act_window">
            <field name="name">Trips</field>
            <field name="type">ir.actions.act_window</field>
            <field name="res_model">res.partner.trip</field>
            <field name="view_type">form</field>
            <field name="help" type="html">
              <p class="oe_view_nocontent_create">
                Click to create a new trip.
              </p>
            </field>
        </record>

        <menuitem action="action_partner_trip_form" name="Trips" sequence="4" parent="base.menu_sales" groups="base.group_no_one"/>
    </data>
</openerp>

I restarted the server and also updated my main package, but the new XML is not loaded into the application. Also, there are no errors inside my logs.

Of course, if I uninstall -> reinstall it, my XML is loaded and my menu items are added, but I lose precious data.
