GeoRSS Error

I get the following error when I try to load a GeoRSS feed - any suggestions?

Error in reading the RSS feed.

Anyone else have trouble with GeoRSS feeds?

Hi Tanya,

How are you adding the GeoRSS feed (it has to be done programmatically)? Can you try using the following feed just to test? I just tried this one and it seems to be working: http://earthquake.usgs.gov/earthquakes/catalogs/7day-M5.xml

Also, from the API Reference, "Only GeoRSS-simple feeds are supported. Geometries are returned in Geographic WGS84. If you are displaying the feed on top of a map in a different projection, they must be reprojected manually when the graphics collection gets features added."

Can you check that you are using a GeoRSS-simple feed?

Thanks Kathy,

The earthquake feed works fine for me. I am not sure if the one I am using is simple or not (how do you tell?). I thought the projection might be an issue so I set it up for the base map and the layer to have the same projection. I also tried to bring the feed into one of my API web application an received the following error:

"An unhandled exception ('Unhandled Error in Silverlight Application
Code: 4004
Category: ManagedRuntimeError
Message: System.Exception: Error in reading the RSS feed. --->
System. Security.SecurityException ---> System.Security.SecurityException:"

Which I had for something similar when the client access policy doesn't have my computer listed. We are working on seeing if that is the problem.

I also came across this post for the api:http://forums.arcgis.com/threads/22714-More-on-GeoRSS...?highlight=georss. I am not sure if this is a problem in the viewer but I will let you know if the client access policy allows me to use it in the viewer.
