Re: Cakephp Transaction

ok i've partially solved the problem! wow!!
in my model:

ClassRegistry::init('Referente');
$Referente = new Referente();

$Referente->CodiceReferente = $elettorez['Elettore']
['ReferenteElettore']; //CodiceReferente is primary key!!
$oldpreferenze=$Referente->field('PreferenzePrevisteReferente');

$actual=(($elettorez['Elettore']['PersoneCollegate']*
$elettorez['Elettore']['ProbabilitaDiVoto'])/100);

$dataSource = $this->getDataSource();
$dataSource->begin($this);

$newpreferenze=$oldpreferenze+$actual;

if($this->save($elettorez)) // ok
{
if($Referente->saveField('PreferenzePrevisteReferente',
$newpreferenze)) // !! insert!
{
return $dataSource->commit($this);
}
}
$dataSource->rollback($this);
return false;

the problem is that saveField make an insert instead of an update
