Hi RJ,
I am having same problem with 10.4.1. I can import the Geofences from a service with the Name field set to a numeric field, but GEP would throws the following error. And, I see the same error whenever Geofence Synchronization occurs, too.
"An unexpected error has occurred while updating the GeoFences from server "Default" in service "Geofences". java.lang.NullPointerException."
has this bug been address in 10.4.1 patches?
Thanks,
Roman
