Hello,

For our Business we sell products sold by m², but packaged by box. eg. We can't sell 1 m², this needs to be rounded to full packages of 1,08m². 

I use an automated action for this, and it works fine for orders in concept state. However on cofirmed orders I get an (blank) error. I Suspected it had something to do with the read-only modifier on order_lines, but after removing the read-only flag the error remains.

On a confirmed order I receive an error with a very strange accompanying log entry:

Error in Log

raise ValueError(_('Posting a message should be done on a business document. Use message_notify to send a notification to an user.'))

Automated action code

def ceil(value):
	return (value - (value%1))+1

product_packaging = record.product_id.x_studio_packaging
product_uom = record.product_id.uom_id
product_packaging_content = float(record.product_id.x_studio_packaging_content)
product_uom_qty = float(record.product_uom_qty)

if product_packaging and product_packaging_content > 0 and product_packaging != product_uom:
  product_package_count = product_uom_qty / product_packaging_content
  if prodct_package_count - int(product_package_count) != 0:
    new_product_uom_qty = ceil(product_package_count) * product_packaging_content
    record.write({
      'product_uom_qty': new_product_uom_qty,
    })

Anybody any idea how to write the sale.order.line to a confirmed order from an automated action?

Thanks!
