I have a number of feature services published to ArcGIS Online from a File Geodatabase with coded value domains, both text and integer field types. All of the domains work great in Collector, the ArcGIS Online map viewer and in the new data tab in item details, with domain descriptions visible.The problem occurs when I add the feature service into ArcGIS Desktop, all of the domain descriptions are gone and only domains codes are shown. I would like to have an environment in which desktop users can view an ArcGIS Online Feature Services updated in the field using Collector and it would be great if the Desktop users could see the domain descriptions and not just the codes.
Nick,
Instead of just adding the feature service straight to Desktop, have you tried exporting your feature service back to a file geodatabase? This may somewhat solve your problem.
