Remove str from IdType, because those kinds of ids are no longer necessary, and lead to unusable recordsets. Because IdType now only contains int and NewId, simplify (and speed up) the conversion of the parameter of browse(). Preferably wrap single NewId into a tuple instead of a list, as tuples are faster. closes odoo/odoo#83687 Signed-off-by: Raphael Collet <rco@odoo.com>
