Hi,

I have added ModuleAVMix module to xml file

```auto
<Module>
<Name>ModuleAVMix</Name>
<Description>moduleavmix</Description>
<Class>com.wowza.wms.plugin.collection.module.ModuleAVMix</Class>
</Module>

```

Then I restarted the server.

Client side AS3 code is like this:

```auto
netconnection.call("getOutputNames", new Responder(someResult))

```

And this is the function that i want to call and written in the ModuleAVMix.java

```auto
public String[] getOutputNames()
	{
		return mixer.getConfiguredOutputStreams().keySet().toArray(new String[0]);
	}

```

However, I have got this warning:

WARN server comment - Missing function: getOutputNames

Also I have this log which seems normal.

INFO application comment - AVMixer.constructor: [avc/_definst_]

INFO application comment - ModuleAVMix.onAppStart No AVMixer config set in properties

Would you tell me what is wrong.

Thanks
