[Inf-IT DAVcl] Duplicate UID after copy

Hi, When I copy (clone) an appointment (click on it, and [Copy] && [Save]) I en dup with two appointments that have the same UID. Even if this is permitted by the specs, there are some tools that have problems with this -- they require all events to have unique ids. Is it possible to generate a new UID for the new appointment? Also: The latest InfCloud release was in 2015. Is it still under active development/maintenance? Regards, Johan
