NullReferenceException: when trying to add xamDayView
posted

Hi,

I just tried to open a wpf-window which contains a xamdayview-control. The designer won't open and throws following exception (sorry, german language):

NullReferenceException: Der Objektverweis wurde nicht auf eine Objektinstanz festgelegt.

Stacktrace

bei Infragistics.Controls.Schedules.ListScheduleDataConnector.ValidateSettings(List`1 errorList)
   bei Infragistics.Controls.Schedules.ScheduleDataConnectorBase.ValidateSettings()
   bei Infragistics.DeferredOperation.InvokePendingOperation()
   bei Infragistics.DeferredOperation.OnAsyncCallback(Object state)
   bei System.Windows.Threading.ExceptionWrapper.InternalRealCall(Delegate callback, Object args, Int32 numArgs)
   bei MS.Internal.Threading.ExceptionFilterHelper.TryCatchWhen(Object source, Delegate method, Object args, Int32 numArgs, Delegate catchHandler)

The errorlist shows

 Der Typeninitialisierer für "Info" hat eine Ausnahme verursacht. (Something like "The type initializer for "Info" threw an exception.")


So I created a new wpf-project and tried to add xamdayview to the empty window. VS 2010 as well as VS 2012 throw the same exception with the same error description/stacktrace

When I try to run the programm I get following error messages

Der Typeninitialisierer für "Info" hat eine Ausnahme verursacht.

Can anyone help me with this issue?

Thanks

    I got a similiar exception using the InfragisticsWPF4.Controls.Schedules.v12.1 within VS 2010 and Windows 8.

    According to 

    http://es.infragistics.com/community/forums/p/72795/368370.aspx

    this seems to be a problem with .NET 4.5

    and also the StackTrace shows a problem at ClrObjectRuntime.CreateInstanceWithCtor

    bei Infragistics.Controls.Schedules.Appointment.StorageProps.Info.get_Instance()
    bei Infragistics.Controls.Schedules.AppointmentListManager..ctor(IScheduleDataConnector connector)
    bei Infragistics.Controls.Schedules.ListScheduleDataConnector..ctor()
