			0 ignored issues – show Bug introduced 2016-12-11 19:37 UTC by Report Bug Copy Issue Report It seems like `$this->getRedirectRouteFromRequest()` targeting `ZfcUser\Controller\Redir...irectRouteFromRequest()` can also be of type `string`; however, `ZfcUser\Controller\RedirectCallback::getRedirect()` does only seem to accept `boolean`, maybe add an additional type check? This check looks at variables that are passed out again to other methods. If the outgoing method call has stricter type requirements than the method itself, an issue is raised. An additional type check may prevent trouble. Loading history...
