How to map 2+ entities to same table in .NET Entity Framework?

I'm trying to create 2 entities that operate as different views on the same underlying db table. When I create these in Visual Studio's entity model and place an association between them, I get a "Association is not mapped" error. I read an article (http://blogs.msdn.com/adonet/archive/2008/12/05/table-splitting-mapping-multiple-entity-types-to-the-same-table.aspx) that describes how to hand-code the XML in the edmx to add a ReferentialConstraint but that didn't help me any.

Any thoughts? Does the designer not support this?

From the error, I'd guess that there wasn't an Association created for the storage schema in the edmx (the SSDL of the edmx XML). A conceptual association has been created if you can see it in the designer, but there's no storage definition behind the scenes. I'm guessin'. =)
