How do you register as a listener for a managed event? Dispatching the Event Now that we have created certain parts of our application, we need to connect them together, basically how to fire the command when our custom event is fired. Email Parslye, but never shown. I cant understand Parsley much, when will you use [inject],messageHandler and manageevents?

Parsley is primarily a Dependency Injection framework. It also offers a very interesting messaging infrastructure. If you just want to run the application and dive into the code, here are the links: Click here to run the application.

Framework Initialization You initialize the Parsley framework using the ContextBuilder class corresponding to the configuration approach you chose. Here is the main application file for the inSync application. Parsley is initialized in the preinitialize event of the application.
In the following example ContactForm. In this case, the ContactService instance created in Config. This is an example of injection by type. Coding to the interface allows us to keep the view decoupled from a specific implementation of IContactService. For simplicity in this sample application, I inject a service directly into the view. The use of an interface provides some level of decoupling, but you can of course use other patterns like the Presentation Model to achieve a greater level of abstraction.
The Dependency Injection and Messaging infrastructure of Parsley will make the implementation of these patterns easier.
Contact; import insync. The event dispatcher and the event handler are decoupled from the framework: You dispatch events the Flex way. That event is defined as a managed event using the ManagedEvents annotation , meaning that the framework will make sure that all the parties interested in that event will receive it.
How do you register as a listener for a managed event? You simply annotate a function with [MessageHandler], and it automatically becomes an event handler for that event, regardless of the display object hierarchy or whether the event bubbles or not.
Alert; import mx. ArrayCollection; import mx. FaultEvent; import mx. AsyncToken; import mx. AsyncResponder; import mx. ResultEvent; import insync. SearchEvent; import insync. If you need finer control, you can use the selector notation to specify the event type. For example in MainView. For example, you can use [MessageBinding] to bind a property of an object to the property of an event. The application is configured to use the MockService ContactServiceMock by default, so it will run without any back-end.
