Hi,

I have been working around with the scheduler and now I have somehow provoked the error underneith.
To provoke the error I drag-resize an appointment in week or day view. The Update method in my custom SchedulerProvider is run without a problem and after that the page just displays the error.

Any Idea what I am doing wrong to make it fail in the Telerik.Web.UI.AppointmentControl.Initialize() method?

Server Error in '/' Application.
