django 1.6.1 raw_id_fields open a 'change' popup instead of 'select' popup

[Vittorio]

django==1.6.1
python==2.7.6
Mac OS X 10.7.5 (development) & UBUNTU Linux 13.04 (production -- Apache 2.2.server)
Browsers==(Mac OS X) Safari, Firefox,Chrome; (Linux) Firefox

To put in a nutshell in my app (I'm translating from Italian into English) 'warehouse' I have a model 'invoice' and a model 'items'. I use the admin interface only.
In an admin form I input all data for a specific invoice (client, date of issue, number of invoice) and, by means of inlines, the ordered items. In these inlines I defined a raw_id_fields referring to the 'items' model which is showing correctly in the form, BUT ... when I click on it a "change" page is often (not always) popping up instead of the expected "select" one.
Tis happens both in development and in production.

Surfing the net I saw a message with the same subject as mine http://stackoverflow.com/questions/21009319/django-1-6-1-raw-id-fields-open-a-change-popup-instead-of-select-popup with a somewhat cryptic only answer...

In my case the pop up window instead of being called by :
http://localhost:8000/warehouse/warehouse/items/?_popup=1 (which - I tested - works great showing a 'select' page)

is called by:
http://localhost:8000/warehouse/warehouse/items/?e=1 (which shows a change page)

Why is that and what should I do?

Thanks a lot
Vittorio

Hello,

Try to delete your browser cache.

No, it isn't a matter of browser cache.
Let's narrow the problem focusing on the linux machine only where there's myapp and the apache2 server.
If I run my app via "python manage.py runserver 192.168.100.100:8000" it all works correctly:

"GET /warehouse/warehouse/invoice/ HTTP/1.1" 200 2145
"GET /warehouse/jsi18n/ HTTP/1.1" 200 2005
"GET /warehouse/warehouse/invoice/5/ HTTP/1.1" 200 22551
"GET /warehouse/warehouse/items/?t=code&_popup=1 HTTP/1.1" 200 21793

and the correct select popup window's shown.

Whilst, *** using the same settings.py file ***, and Apache2 (see the enabled-site conf file below) in production I get a change popup window only and a nasty
/?e=1 appears at the and of the http called page.

Please help, I'm really stranded here.
Thanks a lot
Vittorio
