I need to refetch an entity from the server. As an example, say I have changed the Customer (customerID) on an Order.

So I have:-

_em.RefetchEntityAsync(updatedSalesOrder, MergeStrategy.PreserveChangesUnlessOriginalObsolete, RefetchComplete);

Works except how do I get it to include the new Customer? My ObservableCollection shows the new CustomerID but the old CustomerName.

Anyone? Am I missing something really simple?

Lets look at what I'm trying to do and then maybe someone can help.

I'm using push notification to get the identity of an entity changed by another user (from the save interceptor).

So I thought that using the RefetchEntityAsync ('cos I'm using Silverlight) would be the right option.

What I'm seeing is the field change after the refetch but the customer name in my datagrid still reflects the previous customer name (I'm using an ObservableCollection and raising the property changed event as expected).

But now what would I do if the entity coming in was a new one?

Hi George.

I have reproduced and confirmed that this is a bug.

We are working on a fix and will let you know once it's ready.

Can anyone confirm that with 6.0.8, the RefetchEntityAsync is working?

For a number of reasons, I haven't been using the Refetch until today, and when I turned on that section of code, I'm now seeing a NullReferenceException with the entity being returned.
