Note You normally have to append wsdl to the URL your server registered for a SOA to allow SoapSuds

The second test will test failed requests. We are purposely setting a URL that does not exist "file-thatdont-exists", which will result in a failed service call. The result method onFault expects that the event object will have faultCode param.

Let s see how MVC works in a real ActionScript 3.0 (AS3.0) application. In the chapter s source files, you ll find a folder called BasicMVC. Run the SWF file and press the arrow keys. A status box displays the name of the key you ve pressed, as shown in Figure 1-7. It s an example of what is just about the most basic MVC application that can be written.

[Test(async,timeout="500")] public function testeFailedServicRequest():void { service.url = "file-that-dont-exists"; service.addEventListener( FaultEvent.FAULT, Async.asyncHandler ( this, onFault, 500 ), false, 0, true ); service.send(); }

To let SoapSuds extract the information from a compiled DLL, you use the -ia parameter. soapsuds -ia:<assembly> -oa:<OUTPUTFILE>.DLL -nowp

Figure 1-7. When you press an arrow key, the view informs the controller, the controller updates the model, and the view reads the new data from the model. We re going to take a careful look at this simple application because if you understand it, you ll understand all MVC systems, no matter how much larger or more complex they appear. Before we look at the code itself, let s see how the code is structured, as shown in Figure 1-8.

private function onFault(event:FaultEvent, passThroughData:Object):void { Assert.assertTrue( event.fault.hasOwnProperty("faultCode") ); }

When you run SoapSuds in its default configuration (without the -nowp parameter) by passing only a URL as an input parameter and telling it to generate an assembly, it will create what is called a wrapped proxy. The wrapped proxy can only be used on SOAP channels and will directly store the path to your server. Normally you do not want this behavior, apart from some rare testing scenarios, in which you d just like to quickly call a method on a server during development. Implementing the Server The server in this example will be implemented without any up-front definition of interfaces. You only need to create a simplistic SAO and register an HTTP channel to allow access to the metadata and the server-side object, as shown in Listing 3-22.

BasicMVC is the main application class It imports the model, view, and controller from the mvc package It instantiates them and composes them in just the right way so that they work together These are the most important lines of code in the BasicMVC class: _model = new Model(); _controller = new Controller(_model); _view = new View(_model, _controller); addChild(_view); You can see here that the controller has access to the model because it s being fed a reference to the model in its constructor argument: _controller = new Controller(_model); This makes the model part of the controller s DNA, and the controller can use this reference to the model anywhere in its class To help visualize this, think of the model as a kind a parasitic worm that has infected the controller and is living inside it.

In the testEvent test stub, you are testing and dispatching an event and expecting the results after 500 milliseconds. We set the event type to eventType .

Listing 3-22. Server That Presents a SAO using using using using System; System.Runtime.Remoting; System.Runtime.Remoting.Channels.Http; System.Runtime.Remoting.Channels;

[Test(async,timeout="500")] public function testEvent():void { var EVENT_TYPE:String = "eventType"; var eventDispatcher:EventDispatcher = new EventDispatcher(); eventDispatcher.addEventListener(EVENT_TYPE, Async.asyncHandler handleAsyncEvnet, 500 ), false, 0, true ); eventDispatcher.dispatchEvent( new Event(EVENT_TYPE) ); } [Test(async,timeout="500")] public function testMultiAsync():void { testEvent(); testServiceRequest(); }
