CSLA 4 Silverlight Property Lazy & Child Load error

JJLoubser posted on Friday, April 15, 2011

why on the 1st time load is the return GetProperty(EmployeeContactDetailsProperty); throwing an error:

InvalidOperationException was unhandled by user code? Its not a private backing field but only a child and lazy load object.

private bool IsLoadingEmployeeContactDetails = false;
        private static readonly PropertyInfo<EmployeeContactDetailsEC> EmployeeContactDetailsProperty = RegisterProperty<EmployeeContactDetailsEC>(p => p.EmployeeContactDetails,
            RelationshipTypes.Child | RelationshipTypes.LazyLoad);
        public EmployeeContactDetailsEC EmployeeContactDetails
        {
            get
            {
                if (!IsLoadingEmployeeContactDetails)
                {

                    if ((!FieldManager.FieldExists(EmployeeContactDetailsProperty) || ReadProperty(EmployeeContactDetailsProperty) == null))
                    {
                        IsLoadingEmployeeContactDetails = true;
                        ChildIsBusy = true;
#if SILVERLIGHT
                        if (!IsBusy)
                        MarkBusy();

                        if (IsNew)
                        {
                            //return EmployeeContactDetailsEC.NewEmployeeContactDetailsEC();
                            EmployeeContactDetailsEC.NewEmployeeContactDetailsEC(EmployeeID, (o, e) =>
                            {
                                if (e.Error != null)
                                    throw e.Error;
                                EmployeeContactDetails = e.Object;
                                IsLoadingEmployeeContactDetails = false;
                                if (!IsBusyLazyLoading)
                                MarkIdle();
                                ChildIsBusy = false;
                               

                            }
                           );
                        }
                        else
                        {
                            EmployeeContactDetailsEC.GetEmployeeContactDetails(EmployeeID, (o, e) =>
                               {
                                   if (e.Error != null)
                                       throw e.Error;
                                   EmployeeContactDetails = e.Object;
                                   IsLoadingEmployeeContactDetails = false;
                                   if (!IsBusyLazyLoading)
                                   MarkIdle();
                                  

                               }
                            );
                        }
                   
#else
                      

#endif
                    }
                }

                return GetProperty(EmployeeContactDetailsProperty);
             
            }
            private set
            {
                LoadProperty(EmployeeContactDetailsProperty, value);
                OnPropertyChanged(EmployeeContactDetailsProperty);
            }
        }
