Context is not passed to name_get() in many2one widget in read-only form view

[Lionel Sausin - Initiatives/Numérigraphe]

In the current v7, I noticed that when I set a context on a many2one widget, it is not sent to the server in some situations :
- in the "view ony" form view
- in the editable field in "edit" view
It is however correctly passed to the pop-up list under the editable field in edit mode.
It is also correctly passed to other widgets lik.e many2many-tags

Here is an illustration of this bug: I'm testing the module l10n_fr_naf from lp:openerp-data.
In partners, it adds a many2one to categories. It also imports a big file of official categories, with a 6 levels deep hierarchy.
So it uses a context key to demand short category names for display.
In the attached video you can see that the long name is returned instead, except in the pop-up list. You can see from the console that the key is missing from the context ("LONG" is printed on the console).

Thanks for your tests.
Indeed your video shows a case where it works. Maybe this is only a
problem with name-get?
You can see an example of where it fails using the standard addons here:
lp:~numerigraphe-team/openobject-server/7.0-exhibit-lp1297882-ls
<https://code.launchpad.net/%7Enumerigraphe-team/openobject-server/7.0-exhibit-lp1297882-ls>
You can test it on runbot here:
http://7-0-exhibit-lp1297882-ls-32877-all.runbot.openerp.com/#id=50&view_type=form&model=res.partner.category&menu_id=80&action=68
It's the latest 7.0 server with only 1 line changed: added context to
the parent in partner tags form.
I created a tag tree like this:
- partner
   - telecom
     - level3
       - level4
In "level4", the context demands that the parent be displayed as
"level3" instead of "Partner / Telecom sector / level3" (screenshot
attached).

Mohammed Shekha answered:
"I got your issue, you are not getting context when you are in readonly view and name_get is called.

Note that if you are overriding name_get method and value is coming based on context key then I would prefer always_reload option should set on that many2one field, so I would write something like below.

<field name="parent_id" context="{'partner_category_display':'short'}" options='{"always_reload": True}'/>

Note that when readonly view is displayed then name_get is not called by web-client so if you want to do explicit call of name_get then you must set this option on your many2one field."

"When search read is called to fetch existing record, server already gives key, value pair for records like(id, value) but when there is many2one is in effective_readonly mode(that is readonly view) at that time Web-Client do not call name_get method explicitly, it s server which calls name_get while reading record and at that time server will not having field based context right and hence you might getting wrong name_get value.

always_reload option will forces many2one to call name_get explicitly and hence youwill get proper result based on context."

I have a very similar issue, however I cannot overcome the problem with the options='{"always_reload": True}' as described by Mohammed Sheka. In my case I have a custom stock.location.balance object with a reference to the location. I am trying the group in a search view on the location_id (many2one on stock.location) but the group view will not display the location name but "undefined" despite using always_reload. How can it be enforced to call explicitly name_get?

Then it would probably another proble, and I suggest you file a new bug,
or rather an "issue" on github now.
