In Windows it is possible to do a sum on a “checkbox”, where the domain is INT


In the Universal GUI, this doesn't work

Would be very nice if this option will also work in Universal GUI
….ef_evnt_event_staff_planning?$apply=aggregate(count_using_dinner%20with%20sum%20as%20count_using_dinner_sum)
Results in 500 error :-(.
Is there a way to make that work?
