When I use the EditGeometry, sometimes I experience a NullReferenceException and my app will crash. I managed to catch the exception in my App.cs and I can see in the call stack that it crashes at the point of EditGeometry.UpdateVertexPosition and EditGeometry.HandleElementMove and normally occur after EditGeometry.Action == EditCanceled (but I did not explicitly call EditCancel())</SPAN><BR /><BR /><SPAN>The exception is random and occurs on and off which is a headache. Can Esri developers shed some light on when this exception will occur? Thks!</SPAN></BODY></HTML> Tue, 03 Jan 2012 05:17:30 GMT https://community.esri.com/t5/arcgis-api-for-silverlight-questions/nullreferenceexception-editgeometry/m-p/159039#M3972 Hwee_KiangSim 2012-01-03T05:17:30Z Re: NullReferenceException EditGeometry https://community.esri.com/t5/arcgis-api-for-silverlight-questions/nullreferenceexception-editgeometry/m-p/159040#M3973 <HTML><HEAD></HEAD><BODY><SPAN>I apologize that you were not getting a reply.
