With the patch, all changes (calls to ``write`` method) made in no
'en_US' language will be written in 'en_US' too (in the table model).
Anyway, the behavior is not activated by default, you must be activate
it adding this key-value in the ``openerp-server.conf`` file:
Default language for "model" values hardcoded as 'en_US' should be
Status in Odoo Server:
In the current v5.0, the default language for data strings in objects
is hardcoded to be 'en_US' in the server code.
This complicates usage when the main language in the company is not English.
For example even in a company where all the business is done in French, you cannot change (and correct!) the value of a translatable field in the table, because the new value will be written to ir_translation instead when you don't use en_US.
This is particularly disturbing in companies where English is not used
We should be able to change the default language from en_US to the
locale of our choice, preferably at database creation time, or else in
the server config file or command-line.
This is only for data strings input by users ("model" values in
ir_translate), and the default language for field names, help texts
and other stuff must remain en_US.
