Sorry to bother you again, but i experienced a strange behaviour when trying to resize events in a scheduler placed in an absolute positioned div.
In our UI we have a left menu, and the layout consists of a 100% relative positioned wrapper div with two absolute divs inside. Everything works nicely, except when I try to resize an appointment.
You will see the “preview” is going a bit wildly off to the right. The mouse position used to calculate the new appointment bounds, on the contrary to the preview, is the correct one, so that it can lead to another issue: if you resize for example the right side of the appointment and go left beyond the beginning of the appointment in the past, it sets an end date which is before the start date, leading to the event disappearing (because end date is before the start date). I can verify in my code that the end date is before the start date because these values are saved as such in our database.
