			0 ignored issues – show Comprehensibility Bug introduced 2016-04-02 14:37 UTC by Report Bug Copy Issue Report It seems like you call parent on a different method (`render()` instead of `processSingleSource()`). Are you sure this is correct? If so, you might want to change this to `$this->render()`. This check looks for a call to a parent method whose name is different than the method from which it is called. Consider the following code: class Daddy { protected function getFirstName() { return "Eidur"; } protected function getSurName() { return "Gudjohnsen"; } } class Son { public function getFirstName() { return parent::getSurname(); } } The `getFirstName()` method in the `Son` calls the wrong method in the parent class.
