symfony - there is no active transaction in catch rollback -

i have read should use method commit before persist, didn't solved problem. try use cancel entitymanager before rollback well, didn't solved problem too...

$this->em->getconnection()->begintransaction(); // suspend auto-commit     if($out = $this->em->getconnection()->istransactionactive()) {         var_dump($out);     }     try {         //... work         $history = new promocodehistory();         $history->setcode($code);         $history->setuser($this->getuser());         $this->em->persist($history);         $this->em->getconnection()->commit();         $this->em->flush();          $user = $this->getuser();         $updatedbalance = $user->getbalance() + $code->getsum() - $sum;         $user->setbalance($updatedbalance);         $this->em->persist($user);         $this->em->getconnection()->commit();         $this->em->flush();          $payment = new payment();         $payment->setsum($sum);         $payment->setuser($this->getuser());         $payment->setpromocode($code);          ....     } catch (\exception $e) {         if(!$out = $this->em->getconnection()->istransactionactive()) {             var_dump($out);         }         $this->em->getconnection()->rollback();     } 

before try block istransactionactive() returned me true, in catch block method retrurn me false. how fix it?

i solved problem:

$this->em->getconnection()->begintransaction(); // suspend auto-commit $this->em->getconnection()->setautocommit(false);
