Hey guys, 

You know, in my country (Canada, Quebec), I have two (childrens) taxes to pay. See below (TPS and TVQ) :

Point of sale (POS) has many problem with these children taxes. If a product is setted with these taxes, orders stay on New status, even if validated in POS. Order doesn't get the paid status unless I pay it in Point of sale-> order.

How did you solve the problem?

Documentation :

• https://bugs.launchpad.net/openobject-addons/+bug/1231574?comments=all
• https://github.com/odoo/odoo/issues/1515

TEST :

• I have found two new files at https://github.com/odoo/odoo/pull/1835/files#diff-1c14accbe350f7a177b3e81e5846861b
• I have replaced my two files :
• /home/odoo/addons/point_of_sale/static/src/js/models.js
• /home/odoo/addons/point_of_sale/point_of_sale.py

Now I have the error :
