A while ago someone asked how to bind to a child object's property in a rdlc report. Question here.

The solution was to use an expression like this:

=Fields!ChildObject.Value.SomeProperty

I have recently tried to upgrade to version 10 of the reporting libraries (Microsoft.ReportViewer.WebForms and Microsoft.ReportViewer.Common) and for some reason this does not work anymore. I have got the report rendering and displaying all data fine except any which uses this technique. Instead of the property value i get the text: "#Error"

Why doesn't this work anymore? Anybody know how to to this in the new version?
