Службы данных WCF + 'Веб-ответ содержал неожиданные разделы.ID = 16 'ошибка

/ 16 ноября 2011

Это довольно специфический вопрос, но у меня закончились идеи.Я использую Silverlight 4.0 и WCF Data Services.Ошибка 'Веб-ответ содержал неожиданные разделы.ID = 16 'происходит, когда я вызываю SaveChanges в контексте в клиенте Silverlight.Самое смешное, что один и тот же вызов / код работает для более простого сохранения, но не для более сложных (больше объектов на графике), и я почти уверен, что это сработало за один раз.Кроме того, данные попадают в базу данных, поэтому они должны быть успешными на сервере.

Я собрал пакеты для различных запросов $ batch с помощью Fiddler, и единственное отличие, которое я могу сказать, состоит в том, что существует больше сущностейв том, что не удалось.

DataServiceRequestException генерируется на клиенте в этом коде: 

this.Context.BeginSaveChanges(SaveChangesOptions.Batch, new AsyncCallback((iar) =>
    {
        ServiceOperationStatus status = ServiceOperationStatus.Success;
        try
        {
            // Callback method for the async request, retrieves the status of the requested action
            DataServiceResponse response = this.Context.EndSaveChanges(iar);
             ...

Единственные страницы, которые я нашел при поиске: http://social.msdn.microsoft.com/Forums/en-US/adodotnetdataservices/thread/c81cb454-01f5-4413-a99b-4ad059c5901f http://social.msdn.microsoft.com/Forums/en-US/adodotnetdataservices/thread/3bb4cef6-7f1e-4875-a140-271fe8ebb3cb/ ~, который упоминает многопоточность в Azure, но я почти уверен, что у меня нет этой проблемы.Я вызываю метод save из команды нажатия кнопки.

Буду признателен за любые мысли.Я собираюсь начать просматривать свою базу данных, чтобы убедиться, что что-то не изменилось, чего я не ожидал.Я добавлю больше информации, когда найду ее.

РЕДАКТИРОВАТЬ: добавлен пакетный обработанный пакет $ из Fiddler (я изменил некоторые имена и удалил свойства, чтобы удалить информацию, специфичную для домена)
