Remote SharedObject problem

Hello,

I'm having problems understanding how the connections work in FMS3 with flex 3. This is my code :

quote:

---

case "NetConnection.Connect.Success":
Alert.show("Successful Connection to server");
enterRoom();
break;

---

quote:

---

public function enterRoom():void
{
_so= SharedObject.getRemote("so", _nc.uri, false);
_so.addEventListener(SyncEvent.SYNC, updateUserList);
_so.addEventListener(AsyncErrorEvent.ASYNC_ERROR, onAsync);
_so.addEventListener("sendMessages", onMessage);
_so.client = this;

_so.connect(_nc);
}

---

The shared object does connect. The SyncEvent.SYNC event is dispatched, however when I try to do this :

quote:

---

private function sendMessage():void
{
_so.send("sendMessages", _myName, messageArea.text);
messageArea.text="";
}

---

I get an Async error : Property sendMessages not found on videoconf and there is no default value. The onMessage function doesn't trigger. Do you know why ?

Additionally, how does the call() method work ? I keep getting a Call Failed message, where do I have to define the function in my main.asc ?

Thank you !
