I'm following this sample for ADF libraries

http://edndoc.esri.com/arcobjects/9.2/NET_Server_Doc/developer/samples/Web_Applications/ArcGIS_Buffer_Geoprocessing/ee05ac98-384b-4dbe-b8e3-8d741180dc9a.htm

I'm practically drawing a circle around a point with a geoprocessing service. The radius is about 20 km.

The code is working fine, but the "Clear" routine isn't. Every time I clear the map from the previous data, the memory of the buffer service isn't cleared too and I get this

The code of the "Clear" routine is the same of the sample, but isn't working:

// Clears features from all graphics layers in the resource specified by _graphicsResourceName
protected void ClearGraphics()
{
    // Retrieve the resource and clear its graphics dataset
    ESRI.ArcGIS.ADF.Web.DataSources.Graphics.MapResource graphicsMapResource =
        Map1.GetFunctionality(_graphicsResourceName).Resource as
        ESRI.ArcGIS.ADF.Web.DataSources.Graphics.MapResource;
    graphicsMapResource.Graphics.Clear();

// This won't work too
GeoprocessingResourceManager1.GetResource(0).ClearState();

// Refresh the resource and copy the map's callback results to the callback results collection so
// the graphics are removed from the map
Map1.RefreshResource(graphicsMapResource.Name);
_callbackResultCollection.CopyFrom(Map1.CallbackResults);
}

This should be simple but I can't figure out how to solve this.. the only solution I found is to restart the IIS server which is obviously very bad

Can someone please help me out?

You should go ahead check your own answer as the solution once the system allows you to, that way others know it is resolved. –  RyanDalton Sep 22 '11 at 19:20
