Just recently I was notified it did not work anymore. It seems to be a problem with the basemap being in one spatial reference and my reference layers being in another. I can possibly get my ref layers changed, but this will require an act of congress. I was trying to reproject my reference polygons via GeometryService to project onto my basemap, but got nowhere. My geometries did not return in the callback.
