+
+        When the main language in the company is not English, you cannot change
+        the value of a translatable field in the table if you not switch the
+        client interface to 'en_US', because the new value will be written
+        to ir_translation table instead of the table model.
+
+        This complicates usability, and the default language for "model" values
+        hardcoded as 'en_US' should be configurable
+        (see https://bugs.launchpad.net/openobject-server/+bug/400256).
+
+        With this patch, all changes made in selected default language will be
+        written in 'en_US' too (in the table model) if :
+                  - vals are modified (it is later checked if vals are on
+                        translatable fields)
+                  - more than one language is installed
+                  - default language is set
+                  - current language = default language and not 'en_US'
