Hello everybody,



I have a problem in Odoo 12 that didn't exist in Odoo 11, inside the order_sale_line I have a field calling sheets of type One2Many, inside this field I have another field called sheet_finishing which is also of type One2Many.



I have an onChange routine, which should update both Sheets and Sheet_finishing. But unfortunately that doesn't happen.



Below is the code.

sheets = []
finishing_sheet = []
for x in self.product_id.sheets:
    finishing_sheet = []
    for y in x.finishing_sheet:
        finishing_sheet.append((0, 0, {
            'quantity': y.quantity,
            'finishing': y.finishing.id,
            'finishing_area_boolean': y.finishing_area_boolean,
            'sides': y.sides.id,
            'width': y.width,
            'height': y.height
        }))

    sheets.append((0, 0, {
        'name': x.name.id,
        'quantity': x.quantity,
        'width': x.width,
        'height': x.height,
        'color': x.color.id,
        'midia': x.midia.id,
        'sheet_finishing': finishing_sheet,
        'observation': x.observation,
        'sheet_asset_id': x.sheet_asset_id.id,

    }))
self.update({'sheets': sheets})
