 Two cases need to be distinguisted:
    1) If the storno is a manual storno from the partner, the invoice is set to
-      state 'debit_denied', with 'reconciled' = False 
+      state 'debit_denied', with 'reconciled' = False
       This module implements this option by allowing the bank module to call
-     
+
           netsvc.LocalService("workflow").trg_validate(
               uid, 'account.invoice', ids, 'debit_denied', cr)
 
    2) If the storno is an error generated by the bank (assumingly non-fatal),
-      the invoice is reopened for the next debit run. This is a call to existing

       Should also be adding a log entry on the invoice for tracing purposes
 
-         self._log_event(cr, uid, ids, -1.0, 'Debit denied')

       If not for that funny comment
       "#TODO: implement messages system"  in account/invoice.py
 
    Repeating non-fatal fatal errors need to be dealt with manually by checking
    open invoices with a matured invoice- or due date.
