Problem excluding and eligibling messages
Hi, I have php wamp server and using autobahn.js to send messages. I got a problem excluding clients from receiving messages and to make messages eliglible to certain clients. There is no error messages when I send the message and message is delivered to all subsribers. Problem with my json perhaps?

my code:

``` php
/**
 * {@inheritdoc}
 */
public function onPublish(ConnectionInterface $conn, $topic, $event, array $exclude, array $eligible) {
    $this->app->onPublish($conn, $this->getTopic($topic), $event, $exclude, $eligible);
}
```

My javascript:

``` javascript
var mySessionId = sess.sessionid();
sess.publish("event:"+rID, evt, [], [mySessionId], [] );return;
```

json received by server:

```
[2013-08-16 11:47:08] Sock-In.INFO: onMsg {"from":1253,"len":123,"msg":"[7,\"event:666\",{\"name\":\"chrome666\",\"msg\":\"some message\"},[],[\"520de70a988ef\"]]"} []
```
