Silverlight 4.0 返回少于2项时SL4 RIA出错

我不知道我做错了什么，但每当我的服务模型返回的结果少于2个时，我就会得到一个错误

我在silverlight论坛上发问，一点也不高兴

System.ServiceModel.DomainServices.Client.DomainOperationException:查询“GetEmployees”的加载操作失败。意外的文件结尾。以下元素未关闭：LastModifiedDate、Employee、RootResults、GetEmployeesResult、GetEmployeesResponse。-->System.Xml.XmlException:文件意外结束。以下元素未关闭：LastModifiedDate、Employee、RootResults、GetEmployeesResult、GetEmployeesResponse。 位于System.ServiceModel.DomainServices.Client.WebDomainClient`1.EndQueryCore（IAsyncResult asyncResult） 位于System.ServiceModel.DomainServices.Client.DomainClient.EndQuery（IAsyncResult asyncResult） 位于System.ServiceModel.DomainServices.Client.DomainContext.CompleteLoad（IAsyncResult asyncResult） ---内部异常堆栈跟踪的结束---

我的域服务是基本的，如下所示

[查询（IsDefault=true）]
公共IQueryable GetEmployees（）
{ 
返回this.ObjectContext.Employees.Where（e=>e.IsDeleted==false）；
}

我的xaml看起来像这样

[Query(IsDefault = true)]

我的代码绑定正在处理错误。有人知道我接错了什么吗

我在使用Telerik RadCompression和RadUploadModule HttpModule时遇到了相同的问题。我从我的web.config中删除了下面的两行，一切又开始工作了

<add name="RadCompression" type="Telerik.Web.UI.RadCompression" />
<add name="RadUploadModule" type="Telerik.Web.UI.RadUploadHttpModule, Telerik.Web.UI" />

我也在使用telerik控件，它也导致了同样的问题。解决这个问题的任务真艰巨，telerik压缩导致了这个问题！！
