Error with DayPilotMonth on Navigator.

Hi, I'm a developer, and now, I'm working with DayPilot, concretly with the component Month.

I found a problem. When I try to change the month with the navigator, for example from January to February, I get an error like this:

"An exception was thrown in the server-side event handler"
Index outside of the limits of the array.

I read that it can to be by something of the database, an error connection or similar, but I would like to know if you have found this error sometimes.

Thanks and regards!
