I am getting an HTTP 404 error when I try to rewrite my URL's in Yii with urlManager.

Here are two config formats I've tried in my main.php config file, one like `'pattern1'=>'route1'` and the other in the new format `array('route1', 'pattern'=>'pattern1')`:

```
'urlManager' => array(
            'urlFormat' => 'path',
            'rules' => array(
                'messageBulk'=>'message/apiBulk'
            ),
        ),

'urlManager' => array(
                'urlFormat' => 'path',
                'rules' => array(
                    array('message/apiBulk', 'pattern'=>'messageBulk')
                ),
            ),

```
