Faisal,

I don't see anything wrong with your code except that I would call

SiteContainer.addEventListener(AppEvent.DATA_UPDAT ED, sharedDataUpdated);

outside of the if configXML actually before the if configXML.

Guys,
I am not sure what you are doing wrong. I developed two very simple widgets in SFV1.3 to show how it works and to test the messaging between widgets any they work just fine.

Widget A:

<?xml version="1.0" encoding="utf-8"?>
<BaseWidget xmlns="com.esri.solutions.flexviewer.*" xmlns:mx="http://www.adobe.com/2006/mxml">
 <mx:Script>
  <![CDATA[
   import mx.collections.ArrayCollection;
   
   private function sendMessage():void
   {
    var recAC:ArrayCollection = new ArrayCollection();
    recAC.addItem("Hello World");
    addSharedData("Some Unique Name", recAC);
   }
  ]]>
 </mx:Script>
 <WidgetTemplate id="wTemplate">
  <mx:Button x="10" y="10" label="Button" click="sendMessage()"/>
 </WidgetTemplate>
</BaseWidget>

Widget B:

<?xml version="1.0" encoding="utf-8"?>
<BaseWidget xmlns="com.esri.solutions.flexviewer.*" xmlns:mx="http://www.adobe.com/2006/mxml"
  creationComplete="init()">
 <mx:Script>
  <![CDATA[
   import com.esri.solutions.flexviewer.SiteContainer;
   import com.esri.solutions.flexviewer.utils.Hashtable;
   import mx.collections.ArrayCollection;
   import com.esri.solutions.flexviewer.AppEvent;
   
   private function init():void
   {
    SiteContainer.addEventListener(AppEvent.DATA_UPDATED, sharedDataUpdated);
   }
   
   private function sharedDataUpdated(event:AppEvent):void
   {
    var dataTable:Hashtable = event.data as Hashtable;
    if (dataTable.containsKey("Some Unique Name"))
    {
     var recAC:ArrayCollection = dataTable.find("Some Unique Name") as ArrayCollection;
     var obj:Object = recAC[0];
     //do something with obj
     ta.text = obj.toString();
     dataTable.remove("Some Unique Name");
    }
   } 
  ]]>
 </mx:Script>
 <WidgetTemplate id="wTemplate">
  <mx:TextArea id="ta" width="100%" height="100%"/>
 </WidgetTemplate>
</BaseWidget>

Config.xml entries:

<widget label="Send" icon="com/esri/solutions/flexviewer/assets/images/icons/i_lego.png" menu="menuWidgets" config="">com/esri/solutions/flexviewer/widgets/SendMessageWidget.swf</widget>
  <widget label="Recieve" icon="com/esri/solutions/flexviewer/assets/images/icons/i_lego.png" menu="menuWidgets" config="">com/esri/solutions/flexviewer/widgets/MessagingWidget.swf</widget>

Nadir,

Did you attempt to use the provided widgets and they do not work, or are you saying that you attempted to use the concept in your own code? The example widgets are as simple as I can make, showing how messaging works. I have messaging working on my site since the first release of the SFV, so I still am not sure where you are going wrong. The only thing I can suggest is that you get the Flash Player Debugger version from the Adobe website and add breakpoints into your code to see where it is getting to and not getting to.
