    }

When I work on my local machine server (127.0.0.1,odoo 8 version 8.0-20170429

used for development) It works perfectly, default value is set correctly

When I copy  my module on my synology server with Odoo 8.0.0-0109, default value is not set with exactly the same code...

Someone can helps me for this issue?

Thanks and sincerely yours
