[Question] process log from another contract

[everdreamsoft]

Hello !

I'm trying to register events triggered by a contract to another contract. Basically it would like to register ERC721 transfer generated by a linked contract

 public function processLog(FilterChange $filterChange) {

if ($filterChange->address->hexVal() !== $this->contractAddress) {
            return null;
       }

 if (is_array($filterChange->topics)) {
            $topic = $filterChange->topics[0]->hexVal();
            if (isset($this->events[$topic])) { //todo investigate here
                $transaction = $this->eth->eth_getTransactionByHash($filterChange->transactionHash);
                // We have a relevant event.
                $event = new EmittedEvent($this->events[$topic], $filterChange, $transaction);
                // Process onEventName handler.
                if (method_exists($this, $event->getHandler())) {
                    call_user_func([$this, $event->getHandler()], $event);
                }
                return $event;
            }
        }
        return null;
    }

I changed this method to inject tracked contracts list on order to delegate the call process log

This way

  public function processLog(FilterChange $filterChange, $otherTrackedContracts = null) {

        if ($filterChange->address->hexVal() !== $this->contractAddress) {

            if (isset($otherTrackedContracts[$filterChange->address->hexVal()])){
                $matchingContract = $otherTrackedContracts[$filterChange->address->hexVal()];
                return $matchingContract->processLog($filterChange);

            }
            return null;
        }

        if (is_array($filterChange->topics)) {
            $topic = $filterChange->topics[0]->hexVal();
            if (isset($this->events[$topic])) { //todo investigate here
                $transaction = $this->eth->eth_getTransactionByHash($filterChange->transactionHash);
                // We have a relevant event.
                $event = new EmittedEvent($this->events[$topic], $filterChange, $transaction);
                // Process onEventName handler.
                if (method_exists($this, $event->getHandler())) {
                    call_user_func([$this, $event->getHandler()], $event);
                }
                return $event;
            }
        }
        return null;
    }

Is there a better way ? Running this code I'm getting an issue later processing other events while parsing the ABI.
Not sure it's related but I wonder if this this hack is the cause.

Thanks
