Identify Widget for Flex Viewer - No Loading of Results in Application Preview

I have added the Identify Widget found at the following address;

http://www.arcgis.com/home/item.html...728c50461a1a89


I have loaded two features into this tool in Widget settings and I chose the same URL for both of the feature layers which are found on my ArcGIS Server site. These are the same URLs I provided when adding these features as operational layers when beginning the Application Builder. When I preview my application the Identify Widget appears however when I click on one of the features which I added to the widget no results are loaded.

Any ideas as to what might be the issue?
