Code review comment for lp:~openerp-dev/openobject-addons/trunk-payment-order-tpa

Few remarks:
1. onchange_duedate_search_entries => onchange_duedate
2. onchange_duedate_search_entries method missing domain of credit > 0 and account_id.reconcile = True as shown in old code.
3. Will select the unpaid yet supplier's invoices before the selected due date. => Remove this.
4. Please improve get_obj_ref return variable types.
