hash table does not return data in sharedDataupdate2

NadeemQazi — Tue, 04 Dec 2012 06:16:15 GMT

I have successfully achieved the widget communication following widget communication.pdf Prepared By: Robert J. Scheitlin. I have noticed one thing and it is that when sharedDataUpdated2 is fired the hash table does not contain any data, why it is so?. however when the sharedDataUpdated is fired than array collection data array contains the data. i have applied this lines of code in init function of basewidget:
AppEvent.addListener(AppEvent.DATA_PUBLISH, sharedDataUpdated);
AppEvent.addListener(AppEvent.DATA_SENT, sharedDataUpdated2);
fetchSharedData();

and in the sharedDataupdated2 i have following code:
var dataTable:Hashtable = event.data as Hashtable
however event.data does not contain any data and all of its key are empty as i checked in the debugger. therfore when i checked dataTable.find("KernelDensityData") IT RETURNS FALSE. there only sharedDataupDated returns the data but sharedDataupdated2 does not.
Any thought please.

Nadeem,

Where in your code are you using addSharedData? You can not fetch shared data unless you have added it.

yes i did use addsharedData in my widget that wish to pass the data to other widget.here is the code.

var id:Number = ViewerContainer.getInstance().widgetManager.getWidgetId("widgetLabel");
    var bWidget:IBaseWidget = ViewerContainer.getInstance().widgetManager.getWidget(id, true) as IBaseWidget;
    if (bWidget){
     var vSW:* = bWidget;

     addSharedData("myData", myArray);
where myArray is array collection variable which contains the data that need to be passed in other widgets.
as i wrote before that i have received data in SharedUpDateData but not in sharedDataUpdated2.

Nadeem,

If you keep on post generic code like this I can not tell where you are going wrong in your implementation.
