expecting number but found array

Question

When i access to the form with no rows in the oneToMany field, openErp return:
Uncaught Error: [_.sprintf] expecting number but found array
This error caused by this function:
def _total_presupuestos(self, cr, uid, ids, field_name, field_value, arg, context=None):
result={}
total=0
invoice_obj = self.pool.get('sat.incidencias')
for records_invoice in invoice_obj.browse(cr, uid, ids, context=context):
for records_invoice_lines in records_invoice.presupuesto_id:
total += records_invoice_lines.pv_s

Try this:

def _total_presupuestos(self, cr, uid, ids, field_name, field_value, arg, context=None):
result={}
if not ids:
return result
total=0.0
invoices = self.pool.get('sat.incidencias').browse(cr, uid, ids, context=context)
for records_invoice in invoices:
for records_invoice_lines in records_invoice.presupuesto_id:
total += records_invoice_lines.pv_sin_impuestos
result[records_invoice.id] = total
return result
