Hello, I am currently making a button to "Comfirm", "Validate" and "Post" invoices in one go as our business is small and only one person is doing that it takes too much time and sometimes the secretary get's things wrong and forgets to post and we don't get an invoice number. I have visually created the Button but am trying to call the method when I click it. I created a method called:
def qpost(): in the invoice.py but when I click on the button in tryton it gives me the following error: "Calling Method qpost on model account.invoice is not allowed!" I am new to this so bear with me! Regards, Oscar
