Use case: Allow end user to edit other fields when dragging on the calendar Background: 1. The datetime fields used on the calendar are a formula built from a date field and a time field 2. When a calendar event is dragged, it attempts to change the datetime formula 3. The calendar is only used in day mode Question: Can I tweak the calendar module so that it sets the time field rather than the datetime formula?
Sorry, the calendar feature does indeed only accept date/time fields for the start and end of events and is unable to update formula fields.
