Incorrect sequence when calling Super()

[Luis Felipe Miléo - http://www.kmee.com.br]

Hi,

I have this modules installed:

1 - purchase
2 - account_fiscal_position_rule_purchase ( depends purchase)
3 - l10n_br_purchase ( depends account_fiscal_position_rule_purchase

#l10n_br_core/l10n_br_purchase/purchase.py

    def onchange_partner_id(self, cr, uid, ids, partner_id=False,
                            company_id=False, context=None, **kwargs):
        if not context:
            context = {}
        # TODO try to upstream web_context_tunnel in fiscal-rules
        # to avoid having to change this signature
        fiscal_category_id = context.get('fiscal_category_id')
        if not company_id:
            company_id = self.pool['res.users'].browse(
                cr, uid, uid, context).company_id.id
        return super(PurchaseOrder, self).onchange_partner_id(
            cr, uid, ids, partner_id, company_id, context,
            fiscal_category_id=fiscal_category_id, **kwargs)

#account_fiscal_position_rule_purchase/purchase.py:

    def onchange_partner_id(self, cr, uid, ids, partner_id, company_id=None,
                            context=None, **kwargs):
        if not context:
            context = {}

        result = super(purchase_order, self).onchange_partner_id(
            cr, uid, ids, partner_id)

        if not partner_id or not company_id:
            return result

        kwargs.update({
            'company_id': company_id,
            'partner_id': partner_id,
            'partner_invoice_id': partner_id,
            'partner_shipping_id': partner_id,
            'context': context
        })
        return self._fiscal_position_map(cr, uid, result, **kwargs)

# purchase/purchase.py

    def onchange_partner_id(self, cr, uid, ids, partner_id):
        partner = self.pool.get('res.partner')
        if not partner_id:
            return {'value': {
                'fiscal_position': False,
                'payment_term_id': False,
                }}
        supplier_address = partner.address_get(cr, uid, [partner_id], ['default'])
        supplier = partner.browse(cr, uid, partner_id)
        return {'value': {
            'pricelist_id': supplier.property_product_pricelist_purchase.id,
            'fiscal_position': supplier.property_account_position and supplier.property_account_position.id or False,
            'payment_term_id': supplier.property_supplier_payment_term.id or False,
            }}

In common situations the l10n_br_purchase calls account_fiscal_position_rule_purchase that calls the onchange_partner_id from purchase, but we receive this following error:

TypeError: onchange_partner_id() takes exactly 5 arguments (8 given)

I don't know why the super calling sequence is wrong, but if i uninstall account_fiscal_position_rule_purchase and install l10n_br_purchase everything starts to work properly.

Any one have some issue like this?

Thanks in advance.
