I have a module that create invoice from some datas. In my model, I have a field that is linked to invoicing system (see below). When I create invoices, I put the invoice_id generated by accounting system in this field. I set ondelete to "set null", to remove the invoice Id in my model if I delete an invoice. The problem is that my field is not set to null when I delete an invoice, is still feeded with the original ID of the invoice. I do the same thing with some other models an I don't have any problem. Does the "account.invoice" have some constraints to do that? What is wrong?
invoice_id = fields.Many2one('account.invoice', ondelete='set null')
