Errors other than Application::ERROR_EXCEPTION are missed

[juriansluiman]

Both default error listeners are disabled by the module, but the one now enabled listens only to Application::ERROR_EXCEPTION. There must be a way to connect the other errors to marker interfaces:

ERROR_CONTROLLER_CANNOT_DISPATCH
ERROR_CONTROLLER_NOT_FOUND
ERROR_CONTROLLER_INVALID
ERROR_EXCEPTION
ERROR_ROUTER_NO_MATCH

Suggestion is to map these error codes to a special marker interface. The control structure is then:

$exception = $e->getParam('exception');
if ($exception instanceof Exception\ExceptionInterface) {
    // Continue with interface from $exception
}

$error = $e->getError();
if (array_key_exists($error, $this->applicationErrors)) {
    // Continue with marker attached to error code
}

// Continue with default marker

In case the $exception is not a registered marker interface, the code checks again the error type of the event and as last sets it as default marker.
