Hi, 

I am creating a new payment acquirer module for Beanstream Payment Solutions. For reference, I refered to the payment_ogone to have the same strucutre. Everything is working fine exept that the shopping cart do not clear itself and the system still thinks I am editing the same Sale orde because I am getting this error: It is forbidden to modify a sale order which is not in draft status. After the payment, my quote is set to done.

What am I doing wrong ?

def _beanstream_form_validate(self, cr, uid, tx, data, context=None):   
 status = data.get('trnApproved')    
 res = {        
    'acquirer_reference': data.get('trnId'),        
    'beanstream_txn_type': data.get('trnType'),    
 }    
 if status == '1':        
    _logger.info('Validated Beanstream payment for tx %s: set as done' % (tx.reference))        
    res.update(state='done', date_validate=data.get('trnDate', fields.datetime.now()))        
    return tx.write(res)   
 else:        
    error = 'Received unrecognized status for Beanstream payment %s: %s, set as error' % (tx.reference, status)        
    _logger.info(error)        
    res.update(state='error', state_message=error)        
    return tx.write(res)
