4. Add the boldface text to the <mx:Application> tag to call the initApp() method when

the contact application is initialized:

<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" height="100%"

width="100%" creationComplete="initApp();"

height="100%" width="100%">

Send notes

In this section, you write an event listener method that sends text to the notes destination

when you click the Send button. You then assign that method to the

click event of the Send

button.

1. Add the boldface text to create two-way binding between the log.text property and the

noteProxy.noteText property:

<mx:Binding source="log.text" destination="noteProxy.noteText"/>

<mx:TextArea id="log" width="100%" height="80%"

text="{noteProxy.noteText}"/>

Add the boldface text to the <mx:Button> tag to call the sendMessage() method when

the Send button is clicked:

<mx:Button label="Send" click="ds.commit();"/>

Handle returned data

In this section, you write an event listener method that handles data that the Data

Management Service returns to the client.

Add the following method just below the

initApp() method:

public function resultHandler(event:ResultEvent):void

{

if (event.token == getToken)

noteProxy = ObjectProxy(event.result);

}

In the resultHandler() method, event.token is the AsyncToken that the getItem()

method returns. Because the noteObj object is an anonymous object, the Data Management

Service wraps it in an ObjectProxy object and returns that object in the result event.
