Click on the back button in the model field selector popover used to often remove too many names in the path created via the selector. For example, starting with "partner_id.name" and clicking on the back button in the opened popover would give the invalid path "" instead of "partner_id". We fix that problem. closes odoo/odoo#102156 X-original-commit: e4a7b63c68a87d7afef987e8d036d7ba9c5b6f96 Signed-off-by: Aaron Bohy (aab) <aab@odoo.com> Signed-off-by: Mathieu Duckerts-Antoine <dam@odoo.com>
