Quickstart: Silverlight 4 and WCF RIA

[Henk]

From version 2010.610.1 I tried from the topic in the installed .chm help under: Programmers Guide -> Getting Started -> Quickstart -> QuickStart - Silverlight 4 and WCF RIA. and exactly followed the QuickStart example.

With Select and Update of Customer objects there are no problems. But when I tried to insert a Customer an error is raised on SubmitChanges.

Message: System.ServiceModel.DomainServices.Client.DomainOperationException: Submit operation failed validation. Please inspect Entity.ValidationErrors for each entity in EntitiesInError for more information.
   bij System.ServiceModel.DomainServices.Client.OperationBase.Complete(Exception error)
   bij System.ServiceModel.DomainServices.Client.SubmitOperation.Complete(OperationErrorStatus errorStatus)
   bij System.ServiceModel.DomainServices.Client.DomainContext.CompleteSubmitChanges(IAsyncResult asyncResult)
   bij System.ServiceModel.DomainServices.Client.DomainContext.<>c__DisplayClassd.<SubmitChanges>b__5(Object )    

 
When I inspect ValidationErrors the Error is related to "RentalOrders".
If I remove the link between the Customer and RentalOrder objects in the model it is possible to insert a Customer object.
Can you tell me how I can insert a Customer without removing the the link between the Customer and RentalOrder objects in the model?

Hello Henk,
Sorry for the late reply, I am able to reproduce your problem an will fix it ASAP. The fix will be latest available in the Q2 release.

The workaround is to make the RentalOrders list  internal or expose it as function.

All the best,

Hi Jan,

>The workaround is to make the RentalOrders list  internal or expose it as function.

Hi Henk,
Modify the customer class so that the property is:

private IList<RentalOrder> rentalOrders = new List<RentalOrder>();
internal virtual IList<RentalOrder> RentalOrders
{
    get
    {
        return rentalOrders;
    }
}
