I am using 2010 Q1 version RadScheduler.  I am using Web service binding to a Custom SQL provider.
When I delete a recurring appointment and choose "delete only this occurance", I got javascript error  "Specified cast is not valid".

Here is my code, anyway I can fix it?  Thanks

                 <telerik:RadScheduler runat="server" ID="RadScheduler1" Skin="Office2007" ReadOnly="false"
                        DayStartTime="07:00:00" DayEndTime="21:00:00"                    
                        FirstDayOfWeek="Sunday" LastDayOfWeek="Saturday"
                        <AdvancedForm Modal="true" />
                        <TimeSlotContextMenuSettings EnableDefault="true" />
                        <AppointmentContextMenuSettings EnableDefault="true" />
                        <WebServiceSettings Path="~/Services/CalendarService.asmx" />

Hello Li,

We've fixed a similar issue in the 2010 Q1 SP1 release and later. Can you please check if updating to the latest version (SP2 or the Q2 beta) helps?

Sincerely yours,
