I have a WPF application that allows users to select features on a map; from that selection the application fetches associated data from a specialized service. This was working well until I loaded this layer into a FeatureLayer. No symbols display on the map but you can still perform a select query on the features. Obviously the user needs to be able to see what they're selecting. So this seems like a bug to me.
I tried loading the root service layer (here) as an ArcGISMapImageLayer and that displayed the Meter layer correctly. So I know the layer is there and working, I just can't select features on the map unless it's a FeatureLayer which doesn't render anything.
Any help with this problem would be much appreciated, thanks.
