Hello,
How can I fetchSharedData() From TocItemRender.as ?
Any suggestions ?

Thanks ,

Thanks Robert ! It worked really great.
I only need to change 
fromViewerContainer.addEventListener(AppEvent.DATA_PUBLISH, sharedDataUpdated);

To ViewerContainer.addEventListener(AppEvent.DATA_NEW_PUBLISHED, sharedDataUpdated);

Lu,

So the only thing the fetchSharedData function is doing is dispatching an appEvent:ViewerContainer.dispatchEvent(new AppEvent(AppEvent.DATA_FETCH_ALL));

Which in turn dispatches this event:ViewerContainer.dispatchEvent(new AppEvent(AppEvent.DATA_SENT, dataTable));

in the DataManager.as.

So from W1 dispatch this event:var data:Object =
            {
                key: key,
                collection: arrayCollection
            };
        ViewerContainer.dispatchEvent(new AppEvent(AppEvent.DATA_PUBLISH, data));

and in the toc add this listener:ViewerContainer.addEventListener(AppEvent.DATA_PUBLISH, sharedDataUpdated);

Then just a function that handles the event:private function sharedDataUpdated(event:AppEvent):void
            {
                var data:Object = event.data;

if (data.key == "your Key Name")
                {
                    //todo
                }
            }

Lu,

Maybe you should tell me your workflow and or objective, the more I think about this the more complicated it is getting.

Thanks Robert for your time !.
My workflow - i have a widget "W1" and I want to enable a specific Layer in the TOC (visibility on and off ) only after I get an input from "W1" say hit a "ok" button.

My workaround:
calling addsharedData() in "W1" and passing a boolean value in arraycollection.
fetching the boolean value in TocItemRender.as to on\off the specific Layer.
But i did not get fetchshareddata() funtion here.

please help me out if you could suggest me a better logic or a way to get to fetchSharedData()
 TocItemRender.as .

Thanks Robert again for youe ultimate support.
