ArcGIS Explorer cannot handle KML updates

[VuDang]

Hello,

ArcGIS Explorer is not able to handle empty update responses from KML network links.   When Google Earth received an empty update responses, it ignores the update and maintain the existing data.  When ArcGIS Explorer received an empty update response, ArcGIS Explorer blank out the data from the KML.  Could ESRI team fix this please?  An empty kml response from a KML network link is as follows.  Note there is no data between the <Update> tag

<?xml version=""1.0"" encoding=""UTF-8""?>

     <kml xmlns=""http://www.opengis.net/kml/2.2"" xmlns:gx=""http://www.google.com/kml/ext/2.2"" xmlns:kml=""http://www.opengis.net/kml/2.2"" xmlns:atom=""http://www.w3.org/2005/Atom"">

          <NetworkLinkControl>

              <Update></Update>

          </NetworkLinkControl>

</kml>

Thanks,

Vu Dang

Vu Dang,

Could you attach the KML that your are using, or samples of that show the pattern you are using?

Thanks,
Mark

Hi Mark,

The KML is a network link and it responds with the following KML upon update request from ArcGIS Explorer. Google Earth is able to recognize that this means there is no updates. However, ArcGIS Explorer interprets this response as there is no data and it promptly empties out the map.
