I want to build reports based on ObjectDataSource. As an easy sample, I tried to start with an sample report, based on your video.
In my project, there is a BI-Layer based on EF4/POCO. But when I try to add a Entity Context Object (to populate the List in GetAllProducts()), I get an Error on Report Preview (see Attachment).
In the same Project, I made a report, directly based on an EntityDataSource, which works, even in Preview. But I need to do some processing in my own Classes before.
What's wrong and how to resolve it?
