    <p>Well asynchronous operations always have this affect on code bases, unfortunately there's not really a lot you can do. If your loading operations form some sort of 'Service' then it would be best to make a IService interface, along with the appropriate MVC Style architecture and use data tokens. Briefly:</p> <pre><code>//In your command or whatever var service:IService = model.getService(); var asyncToken:Token = service.someAsyncOperation(commandParams); //some messaging is used here, 'sendMessage' would be 'sendNotification' in PureMVC var autoCallBack:Function = function(event:TokenEvent):void { sendMessage(workOutMessageNameHere(commandParams), event.token.getResult()); //tidy up listeners and dispose token here } asyncToken.addEventListener(TokenEvent.RESULT, autoCallBack, false, 0, true); </code></pre> <p>Where I have written the words 'workOutMessageNameHere()' I assume is the part you want to automate, you could either have some sort of huge switch, or a map of commandParams (urls or whatever) to message names, either way best get this info from a model (in the same command):</p> <pre><code>private function workOutMessageNameHere(commandParams):String { var model:CallbackModel = frameworkMethodOfRetrivingModels(); return model.getMessageNameForAsyncCommand(commandParams); } </code></pre> <p>This should hopefully just leave you with calling the command 'callService' or however you are triggering it, you can configure the callbackMap / switch in code or possibly via parsed XML. Hope this gets you started, and as I've just realized, is relevant?</p> <p>EDIT: Hi, just had another read through of the problem you are trying to solve, and I think you are describing a series of finite states, i.e. a state machine. It seems as if roughly your sequences are FunctionState -> LoadingState -> ResultState. This might be a better general approach to managing loads of little async 'chains'.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
