hi I posted this question under WPF forum but no luck finding any response so try my luck in silverlight forum.
I am using esri for WPF v2.3. 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())
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!
