Estou tentando fazer um form com troca de se senha sem acesso ao sistema. Mas dá um erro muito escroto que buga todo o sistema.

segue o código:

public function onSave($param)
{
try
{
$this->form->validate();
TTransaction::open('permission');
$object = $this->form->getData();
$user = SystemUser::newFromLogin($object->login));




if (SystemUser::newFromLogin($object->login) instanceof SystemUser)
{

if ($object->pergunta_secreta_id == $user->pergunta_secreta_id) and ( md5($object->resposta_secreta) == $user->resposta_secreta)
{


$user->password = md5($object->password);

}


}
else
{

throw new Exception(_t('Current CPF does not match'));
throw new Exception(_t('Current question does not match'));
throw new Exception(_t('Current question does not match'));

}




if ($object->repassword != $object->password)
{
throw new Exception(_t('New password does not match the confirm password'));
}
// stores the object

$user->store();

// fill the form with the active record data
$this->form->setData($object);



// close the transaction
TTransaction::close();

// shows the success message
new TMessage('info', _t('Password changed successfully'));


}
catch (Exception $e)
{
new TMessage('error', $e->getMessage());

TTransaction::rollback();
}
}




public static function onReload()
{
AdiantiCoreApplication::gotoPage('RecuperaSenhaForm', '');
}

}
