In an app for school floorplans with both map and feature services, selecting a visible feature to edit also selects features on other layers (other floors of the building) that aren't visible. In other words, with the edit widget open, I select a room (polygon) on the first floor to edit attributes, and the edit pop-up shows it and features from the second floor that aren't visible.
I assume this has something to do with having feature and map services together, but otherwise we have to have separate editors and viewers, which is cumbersome.
Curently this is by design as the editor widget is not confined to only edit features that are visible. You can contact esri tech support and log an enhancement request for your workflow. Also you can submit an Idea to the ArcGIS Ideas space:
