SuperObject Notification

[mrbar2000]

Hi friend,

There are some way to use DOR server with a desktop client
application? How we can do this?

[Henri Gourvest]

you mean a client GUI application ?
in wich programming language ?

[Marcos Barreto]

Yeah, a GUI VCL desktop application! How do This?
I want too see with you if there is way to integrate Flex and DOR!
My goal is create the same server application and use the same exchange message protocol with differents client applications.

I have never used Flex before, but it was easy to create a sample
program that interprets JSON data from a DOR server.
I used this additional library: http://code.google.com/p/as3corelib/
and take a look here:
http://ntt.cc/2008/10/06/as3corelib-tutorial-how-to-use-json-class-in-flex.html

With Flex, data controls can automatically render xml, so you could
automatically create an xml view from superobject in the Dor Server.

xmlns:s="library://ns.adobe.com/flex/spark"
xmlns:mx="library://ns.adobe.com/flex/mx">

<fx:Script>

import mx.controls.Alert;
import mx.rpc.events.FaultEvent;
import mx.rpc.events.ResultEvent;
import mx.rpc.http.HTTPService;
import mx.utils.ObjectUtil;

private var srv:HTTPService

protected function button1_clickHandler(event:MouseEvent):void
{
srv = new HTTPService();
srv.url = "http://server/controller/action.json";
srv.method = "GET";
srv.resultFormat = "text";
srv.addEventListener("result", httpResult);
srv.addEventListener("fault", httpResult);
srv.send();

}
public function httpResult(event:ResultEvent):void {
var result:Object = JSON.decode(event.result.toString());
memo.text = JSON.encode(result);
}

public function httpFault(event:FaultEvent):void {
var faultstring:String = event.fault.faultString;
Alert.show(faultstring);
}

</fx:Script>
<s:Button x="55" y="58" label="Button"
click="button1_clickHandler(event)"/>
<s:TextArea id="memo" x="44" y="116" width="374" height="221"/>
</s:WindowedApplication>

Ok. But what about VCL desktop applications? To update GUI I need receive notification of changes on superobject properties and lists!

[Henri Gourvest]

I do not understand what you expect of me.

the client sends a request to the server and the server responds.

the server does not send notification to the client asynchronously.

Maybe this is a wrong forum to this. i think that i have post on superobject forum.
I want know how use the superobject returned from server in my desktop application.
How use it as a common object?
Person.Name instead Person.S['Name']
And how I can be notified when changing the superobject data? Person.Name := 'Marcos'
