The ArcGISTiledMapServiceLayer is http://services.arcgisonline.com/ArcGIS/rest/services/World_Imagery/MapServer
My FeatureLayers are GeodatabaseFeatureTables coming from a local geodatabase file.
The SpatialReference for the Service is 102100.
The SpatialReference for the geodatabase/FeatureLayers is 2285.
If I add just the FeatureLayers to the map, it looks fine.
If I add the Imagery Map Service and then my FeatureLayers, I see only the Satellite Imagery. My FeatureLayers seem to load ok, but are not visible on the map. At least there are no errors in my LayerLoaded handler.
If I force the code to load my feature layers first, so the Map has a spatial reference of 2285, then add the Image Service layer, I get the following error in my LayerLoaded handler.
"Layer cannot be displayed on a Map with a different spatial reference."
Any ideas how I can get these two data sources to play nice together?
