… user Steps to reproduce: ------------------- - install the "hr" module; - remove access rights for "Employees"; - change language on the user profile. Issue: ------ There's an Access Error because we can't read the `private_street` field on the employee that corresponds to the user. Cause: ------ The new version of onchange fetches the record values on the server side, unlike the old version which used the values in the view. In the old version, as we were using view values, this didn't cause any problems, as the values came from a read that which took into account `SELF_READABLE_FIELDS`. Note: We do not have access to the value of the `private_street` field because it is a related field with the attribute `related_sudo=False` and we do not have access rights for the `hr.employee` model. Solution: --------- Use the cache and place the values of the fields in `SELF_READABLE_FIELDS` in it before performing the onchange logic. opw-3664929
When the server-side form view reads its record, the call to web_read() leaves data in cache, which may prevent some access error to be triggered in the first call to onchange(). In order to avoid that, simply clean up the environment like after the other method calls.

Cherry-picked two fixes that avoid Access Error because can't read some fields on the employee that corresponds to the user.
Original PR:
odoo#148997
There was a refactor of class Form between 16.0 and 17.0 versions. The class moved from tests/common.py (16.0) to tests/form.py (17.0), so I just copied the two lines of the fix in
_init_from_valuesmethod.
