Hi Josh,
you should use the automatic mapping between Java ValueObjects and
ActionScript ValueObjects. For that your ActionScript VO should look
like this:
/***
AS class
***/
// ActionScript Document
class Person {
var name:String;
var birthdate:String;
public static var registeredClass:Boolean =
Object.registerClass("[full path in WEB-INF / java class name]",Person);
}
Don't use a constructor in the AS VO, the constructor is called AFTER
FLEX filled the attributes from the Java VO.
Your MXML file could look like this:
/***
MXML File
***/
<mx:Application xmlns:mx="http://www.macromedia.com/2003/mxml";>
<mx:RemoteObject id="peopleObject" source="People">
<mx:method name="getPerson"
result="handleResults(event.result)"/>
</mx:RemoteObject>
<mx:Script>
<![CDATA[
import Person;
var my_person:Person;
function handleResults(event){
my_person = event.result;
}
]]>
</mx:Script>
<mx:Panel width="800" height="600">
<mx:HBox>
<mx:Form>
<mx:FormItem label="Person name">
<mx:Label text="{my_person.name}" />
</mx:FormItem>
<mx:FormItem label="birthday">
<mx:Label text="{my_person.birthdate}" />
</mx:FormItem>
</mx:Form>
<mx:Button label="Get Person"
click="{peopleObject.getPerson()}" />
</mx:HBox>
</mx:Panel>
</mx:Application>
I coded everything in my mail app, so I'm not totally shure if the code
runs at once.
Greetings
Christoph
