Hello,

I dont know how to change many2one field in onchange method.

What i need to do is: when someone is creating a new invoice and changing currency, bank account changing in the same time. I'm using exception to have a look at the value of partner_bank_account.

@api.onchange('currency_id')

	def currency_id_change(self):

		if self.currency_id:

			return {

                            'value': {

                                'partner_bank_id': ????????????????,

                                    }

                                }

			raise except_orm(('Warning!'), (self.partner_bank_id))
