Log Message:
Expose a public read-only property httpService on HTTPOperation. HTTPOperation.service will still return null as a consequence of an old design decision (HTTPService does not extend AbstractService), but a warning is now logged to inform the user that they should use HTTPOperation.httpService to access the containing service.
Doc notes: Please explain that if a standard HTTPService is used, the event.target on the ResultEvent from this service is an instance of HTTPOperation, and users can access the originating HTTPService with event.target.httpService. (see bug for use-case)

For a TwoWay binding to work the source property must have public setter and an anonymous object (like the one your select new LINQ query creates) has not.
But since you are binding to the Text property of TextBlocks you could just remove Mode=TwoWay from the bindings in the ItemTemplate of the ListBox:
<TextBox Name="txtOrderID" Text="{Binding Path=OrderID,Mode=OneWay}" Margin="5,0,10,0" Width="30"/>
<TextBlock Text="Order Date:" TextAlignment="Right" Width="80"/>
<TextBlock Name="txtOrderDate" Text="{Binding Path=OrderDate,StringFormat={}{0:MM/dd/yyyy}}" Margin="5,0,10,0" Width="75"/>
<TextBlock Text="Required Date:" TextAlignment="Right" Width="80"/>
<TextBlock Name="txtRequiredDate" Text="{Binding Path=RequiredDate,StringFormat={}{0:MM/dd/yyyy}}" Margin="5,0,10,0" Width="75"/>
There is no reason to bind TwoWay to a TextBlock.
Hope that helps.
