I have created a map service based on a locally hosted ArcGIS Server feature service containing a number of sign types for collection and editing. In the .MXD that defines the feature service, the sign layer template is setup with the signs in a specific, alphabetic order. In the feature service that is published from said .MXD, the signs are still in their alphabetic order. Once I put the feature service into an ArcGIS online web map and open it in collector however, the sign types are completely randomized, with no order whatsoever. Why? FWIW, this is all 10.2 from top to bottom, so no easy outs here saying, "Upgrade to the latest version" 😉
