I have a Navigator component changing a single day calendar component showing events for the day. I can change the BusinessHoursStart and End and use the DayPilotCalendar_BeforeCellRender event to set the isBusiness flag and hide the non-business hours. The problems occurs when I want to change to a day with different business hours (shorter), I receive an Jscript error when the control is rendered. If I ignore the error in debug, the control paints, but shows the first set of business hours.

Is there a way to refresh the control's properties?

By the way, nice job on this product!
