I have a report, which is filled with an object from an entity framework query.
I want to acces a property of a parent class, like it is described at http://wraithnath.blogspot.de/2011/04/reportviewer-object-datasource-nested.html
But i keep getting the error that the given Expression "=First(Fields!Model.Value.Name)" is invalid.
All names are spelled correct.
Do you have any idea how to fix this??
