ArcGIS Server 10.3, ipad Air (iOS)
I have a service to which I can successfully add a new feature while disconnected. Then, with connectivity restored, I sync. The sync appears successful. But the new feature is not written to the database. A json query of the rest endpoint for its ID returns "no results," and the geometry is not present in the feature class.
Adding a feature to the same service while connected is successful. So it appears to be related to the sync.
How can I troubleshoot this?
You might want to change server log setting to verbose or debug and get more details while sync
Also, you can use Fiddler to capture the whole sync traffic in your iOS device http://docs.telerik.com/fiddler/configure-fiddler/tasks/ConfigureForiOS
In those two ways, you might have interesting finding.
I don't have Portal. I do have an ArcGIS Online Organizational account, and no, the feature is not there. I also queried the REST endpoint, and the feature is not there. It does not exist in the database, it only appears on the ipad, in the downloaded extent. I even checked another web map, on the ipad, which uses the same feature service. It isn't there, either.
