I want to prevent user to add the same product in multiple line for stock.picking, i did it successfully on the Odoo backend and i raise a warning for this, but i see that i can still add the same product by using stock picking client UI into stock_barcode module in i know that require some JS code to have a complete solution, can any one guide me about that with how to inherit and modify confirm action in this view to block the user
Thanks in advance
