I am developing a plugin, where I need to update the „QueryBuilderFactory“ class. For that reason I subscribed to the „Enlight\_Bootstrap\_AfterInitResource\_shopware\_searchdbal.dbal\_query\_builder\_factory“ event, and in the listener I am setting my own created class by following code:

> $coreService = Shopware()-\>Container()-\>get(‚shopware\_searchdbal.dbal\_query\_builder\_factory‘);  
> Shopware()-\>Container()-\>set(‚shopware\_searchdbal.dbal\_query\_builder\_factory‘, new QueryBuilderFactory($coreService, $this));

Where QueryBuilderFactory is the class that I have created, the namespace is different. But unfortunately In the listing page I am getting the following error:

> core.ERROR: TypeError: Argument 1 passed to Shopware\Bundle\SearchBundleDBAL\FacetHandler\VoteAverageFacetHandler::\_\_construct() must be an instance of Shopware\Bundle\SearchBundleDBAL\QueryBuilderFactory, instance of Shopware\_Components\ListingUpdate\Bundle\SearchBundleDBAL\QueryBuilderFactory given

The php version of server is 7.0.9. So I guess it has something to do with the PHP version, because I read that in PHP 7 this strict mode for types is introduced.&nbsp;  
So my question is, are there any workarounds&nbsp;(php version can not be changed)?&nbsp;
