I want to limit the number of appointment that can overlap at the same time.
I found here how to limit that when a new appointment is created. However, lets say I want to limit to 2 appointment that overlap, I create two appointments from 8 to 9 and one from 10 to 11, if I drag and Drop the 10 to 11 to 8:30-9:30, the system will not detect that the limit is reached.
When I look in the update, the appointment that I get as "sender" is the one with the old start and end, so it is not detected as being in the interval by using "
Can you help me ?
