In this article I would like to give you a tutorial in order to invoke SAP web tutoriall with Flex using Cairngoorm framework. Cairngorm is one of the primary MVC open source frameworks for application architecture in Adobe Flex.
Flfx in the view are bounded with view locator application objects and throws events such as ClickedDraggedDropped and so on. Manage the business logic of your application.
First of all we need to create a SAP web service for our test. It is out of scope of this weblog to calrngorm you the how to… You can read this web post on this blog Create a web service with ECC 6. This is our Model Locator, this is a singleton class, and so only one instance of this class is active in the same execution. As described above, this class will be used to store all Application Value Objects.
What we need to have a fully customized template for our Flex project is the delegator and the remote repository. In the business folder we create to files: The project, as it is, is a fully customized Cairngorm one; you can use this template as default for all of your projects.
We need to create the value objects that will store values to be displayed on our views. This object is very simple right now and it is not in scope of this tutorial to perform any other development.

In real projects is useful to enhance this Value Object in order to be similar to a Java Bean with get and set methods for each attribute e. For this tutorial we need two views: It would be enough only one view, but I prefer to create two views in order to explain how is possible to change view with the Model Locator. Open Welcome view in design mode and create a button and associate function onConnect to the onClick event as show below:.
Save and close Welcome view and now edit CompanyList view.

In desing mode create a new DataGrid as shown below:. We need to register event in the Front Controller and create the Command object in order to manage the business logic. Open your Front Controller and in the function initializeCommands insert the following instruction:. Now, our event is registered and every time event Connect is thrown framework will invoke fpex ConnectCommand. In the folder commands create a new ActionScript Class named ConnectCommand ; in the interface list add these interfaces: ICommandIResponder mx.
When front controller handles the event, it instantiates a new ConnectionCommand and invokes method execute. The command instance calls the delegate method and waits for the result.
If the remote call is successful the framework invokes result method, in this method we retrieve the event result and store it value in the Model Locator Value Object. The last step is to implement the remote call tutoeial the Delegate class; open this file and add this function:. In order to be sure to call the right method, you can get the remote function name looking into the WSDL definition.
We are ready to execute our application. Before you tutkrial you have to be sure that the crossdomain. More information are available on this blog Add crossdomain.
