nHibernate 2.0 - mapping a composite-id *and* many-to-one relationship causes “invalid index” error

Question

I have a problem. Imagine this data model:

[Person] table has: PersonId, Name1  
[Tag] table has:  TagId, TagDescription  
[PersonTag] has: PersonId, TagId,         


        

Answer 1

Kay, here's the answer. Little-to-no documentation on this:

This will allow you to create a composite-id made up of the inverse of a many-to-one relationship.

Good hunting...
