Do Rollback in onValidationFails

According to the official documentation. The operation is already stopped. "Is executed before the validation process only when an insertion operation is being made" https://docs.phalcon.io/en/latest/reference/odm.html#validation-events-and-events-manager

Yes, the operation is already stopped. "Is executed after an integrity validator fails" https://docs.phalcon.io/en/latest/reference/models.html#events-and-events-manager, but the transactions don't finish. I don't understand because the transaction don't finish.

My code is:

class Table1 extends \Phalcon\Mvc\Model
{
    public function initialize()
    {
        $this->setSchema("public");
        $this->setSource('Table1');

        $this->hasOne('id',"Module\\Models\\Table2",'id', array(
            'foreignKey' => array(
                'action' => Relation::ACTION_CASCADE
            ),
            'alias' => 'session'
        ));
    }
}

class Table2 extends Table1
{
    public function initialize()
    {
        $this->setSchema("public");
        $this->setSource('Table2');

        $this->hasOne('id',"Module\\Models\\Table1",'id', array(
            'foreignKey' => array(
                'action' => Relation::ACTION_CASCADE
            ),
            'alias' => 'session'
        ));
    }
}

In Table2:

public function save($data=null, $whiteList=null){

    if(is_array($data) && !empty($data)){

        $this->assign($data);

        //Create a transaction manager
        $di = $this->getDI();
        $manager = $di->get('transactionManager');

        // Request a transaction
        $transaction = $manager->getOrCreateTransaction();

        try{
            $table1 = new Table1();
            $table1->setTransaction($transaction);
            if ($table1->save($data) == false) {
                $transaction->rollback(EXCEPTION_DB_ERROR . " " . implode(",",$table1->getMessages()));
            }

            $this->setTransaction($transaction);

            $this->table1 = $table1;
            $this->id = $table1->getId();

            if (parent::save($data) == false) {
                $transaction->rollback(EXCEPTION_DB_ERROR . ": " . implode(",",parent::getMessages()));
            }

            $metaData = $session->getModelsMetaData();
            $attributes = $metaData->getAttributes($session);

            //Force attributes from parent into child
            foreach($attributes as $attr){
                $this->$attr = $table1->$attr;
            }

            $transaction->commit();

        }catch(Exception $e) {
            throw new \Helpers\Exception(EXCEPTION_DB_ERROR, $e->getMessage());
        }

    }elseif($this->id) {
        $this->edit();
    }
}
