Hi, I'm developing REST Server Object Extensions for ARCGis 10.2.1, I found I could add my own properties to let the admin set configuration parameters. See ArcObjects Help for .NET developers . Arcgis Server Manager shows automatically the textboxs to set the properties values . The problem is the Arcgis Server Manager does not save the value set by the admin and the next time that he open the capabilities page of my service extension Arcgis Server Manager shows the default values again loosing the values.
Did you ever get this issue resolved?
