@tde-banana-odoo  if we call render method of ir.ui.view with new api then it will work fine till website module is not installed, once website module is installed, it will raise the traceback due to mismatching the arguments as in website render method is override with old api, if we dont want this change then we need to keep our method in old api. and base render method itself use @api.cr_uid_ids_context decorator, so i think there is not an issue with mapping. Thanks
