Print Page - CoCoMo and PureMVC advices needed

Hi guys,

I was building a collaborative project using PureMVC, now i see that CoCoMo is knocking at the door and it will simplify a lot of work if we use it for our project.

The thing i dont know is how to integrate PureMVC with it.

Looking a this simple chat code coming from CoCoMo examples

<?xml version="1.0" encoding="utf-8"?> 
<mx:Application 
	xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" 
	xmlns:rtc="CocomoNameSpace"> 
	
	<mx:Script>
		<![CDATA[
			import com.adobe.rtc.pods.simpleChatClasses.ChatMessageDescriptor;
			import com.adobe.rtc.events.ChatEvent;
			import com.adobe.rtc.pods.simpleChatClasses.SimpleChatModel;
			
			// This simple example just shows how this shared model can be made easily bindable for MXML.
			// See SimpleChatModel for details.
			
			[Bindable]
			public var chatModel:SimpleChatModel;
			protected function buildModel():void
			{
				// Create the model: just calling the constructor won't create the collection node or pass the messages.
				// Call subscribe and give it a shared ID while creating the model. 
				// The shared ID becomes the name of the collection node.
				chatModel = new SimpleChatModel();
				chatModel.sharedID = "myChat_SimpleChatModel";
				
				chatModel.subscribe();
				chatModel.addEventListener(ChatEvent.HISTORY_CHANGE, onChatMsg);
				this.addEventListener(KeyboardEvent.KEY_UP, onKeyStroke);
			}
			
			protected function submitChat(str:String):void
			{
				var cmd:ChatMessageDescriptor = new ChatMessageDescriptor();
				cmd.displayName = cSession.userManager.getUserDescriptor(cSession.userManager.myUserID).displayName;
				cmd.msg =  str;
				chatModel.sendMessage(cmd);
				chat_mesg_input.text = "";
			}
			
			protected function clearChat():void
			{
				chat_mesg_area.text = "";
				chatModel.clear();
			}
			
			protected function onChatMsg(p_evt:ChatEvent):void
			{
				if(p_evt.message != null && p_evt.message.msg != null && p_evt.message.displayName != null)
					chat_mesg_area.text += "\r\n" +  p_evt.message.displayName + ": " + p_evt.message.msg;
				else
					chat_mesg_area.text = "";
			}
			
			protected function onKeyStroke(p_evt:KeyboardEvent):void
			{
				if(p_evt.keyCode == Keyboard.ENTER) {
					submitChat(chat_mesg_input.text);
				} 
			}

	<!-- 
		You would likely use external authentication here for a deployed application; 
		you would certainly not hard code Adobe IDs here.
	-->
	<rtc:AdobeHSAuthenticator 
		id="auth" 
		userName="AdobeIDusername" 
		password="AdobeIDpassword"  />
		
	<rtc:ConnectSessionContainer roomURL="YourPersonalRoomUrl" id="cSession" authenticator="{auth}" width="100%" height="100%"> 
		<mx:Canvas width="100%" height="100%" creationComplete="buildModel()"> 
			<mx:VBox id="chatBox">
				<mx:TextArea width="800" height="500" id="chat_mesg_area"/>
				<mx:TextInput width="400" id="chat_mesg_input"/>
				<mx:HBox>
					<mx:Button label="Submit Chat" click="submitChat(chat_mesg_input.text)"/>
					<mx:Button label="Clear Chat" click="clearChat()"/>
				</mx:HBox>								
			</mx:VBox>
		</mx:Canvas> 
	</rtc:ConnectSessionContainer> 
</mx:Application>

What would be the convertion path to a PureMVC way

Myapp.xml will sendNotification( STARTUP, app );
Which call StartupCommand

Which registers Proxies: what are my proxies here ?
ConnectSessionContainer give access to many stuff:
authenticator : AbstractAuthenticator
autoLogin : Boolean = true
fileManager : FileManager
initialRoomSettings : RoomSettings
isSynchronized : Boolean
roomManager : RoomManager
roomURL : String
streamManager : StreamManager

What would be his place in PureMVC ?

ChatMessageDescriptor is a "simple value-object to describe chat message properties." where should i put it ? in a descriptor folder along my models ?

cmd.displayName = cSession.userManager.getUserDescriptor(cSession.userManager.myUserID).displayName;

chatModel will be in a ChatProxy as a VO ?

Since here the View talk to the ChatModel directly with bindable there is no mediator. Should i add one ?

Thanks for your answers i want to continue using PureMVC. :D
