GeoRSS projection

Question

I am trying to use a GeoRSS feed that seems to be in geographic cooridantes so it will overlay in google maps.  When I try and use this feed in the Flex Viewer it shows the points all over the world.  Is there anything i can do to use this feed in the Flex Viewer?  Thanks.

Carl, If you have the ability to change code and recompile the viewer than there is a simple fix for this. Replace the GeoRSSUtil.as code with this://////////////////////////////////////////////////////////////////////////////// // // Copyright (c) 2010-2011 Esri // // All rights reserved under the copyright laws of the United States. // You may freely redistribute and use this software, with or // without modification, provided you include the original copyright // and use restrictions.

Thanks.  I will look at videos.  I am not a programmer and was hoping there was a way to use the GeoRSS widget that is provided with the ArcGIS Viewer for Flex.  Thanks again.
