The Final Code
Here's the final code for the chat, ready to compile and run. It rings in at a svelte 70 lines.
package {
import flash.display.Sprite;

protected var chatRoom:Room;
protected var incomingMessages:TextField;
protected var outgoingMessages:TextField;
public function UnionChatPart1 () {
buildUI();
reactor = new Reactor();
reactor.addEventListener(ReactorEvent.READY, readyListener);
reactor.connect("tryunion.com", 80);
}
protected function readyListener (e:ReactorEvent):void {
incomingMessages.appendText("Connected to Union\n");
chatRoom = reactor.getRoomManager().createRoom("chatRoom");
chatRoom.addMessageListener("CHAT_MESSAGE", chatMessageListener);
chatRoom.join();
}
protected function buildUI ():void {

}
