Hi,
I created the same new fields on account_tax and account_invoice_tax. I
created a new tax and filled those fields.
What I want is: when I insert a new product on a invoice those fields
must to be filled with the same information that was registered when I
configured the tax of this product.
To get this I need to modify Invoice._compute_tax and
InvoiceTax.on_change_tax. I did this on core (to test) and it worked. To
do this on my module I saw that Invoice._compute_tax is called by
Invoice.on_change_lines and I try to call this method on my module for
when user alters a line all the tax information will be automatically
filled. I did this:
class Invoice:
__name__ = 'account.invoice'
...
def on_change_lines(self):
super(Invoice, self).on_change_lines()
But it gives me the error: 'NoneType' object has no attribute 'items'
