I’m using the version 1.4.6 over centos 6 and see a possible bug, when create a invoice all work as well, you apply the discount (image 1) and show correctly but when export to pdf, the total amount of the item not show correctly, show the amount without the discount (image 2).
experiencing the same issue. on a discounted item, the item non-discounted total amount shows on the PDF item “total” instead of the discounted amount, but the total and balance amount for the items combined total is correct. the invoice was previously saved, and I tried the client view with the same results.
it appears to me that the PDF creation is reading the “Subtotal” value instead of the “Total” value for that particular item.
