Is that a good way to title this? Do we have a better name for that object that has both foreign keys?
Anyway, I am using a set of externally designed data types. Among them is the connection between two of my entities, Schools and Students. Each student can attend many schools. Each school has many students. In addition, that period of attendance has a start and end date, etc. I have constructed a mapping and it almost works. Two problems I need help with: 1) I am getting an error, "Cannot insert the value NULL into the column RefId." It specifies the join table. RefId is the <id> column for this intermediate. I bet that the problem is that NH doesn't expect there to be an id on the joining table. 2) I can't set said start and end dates because I can't find a way to address that intermediate object. I considered the idea that I should initialize that object in the AddStudent() (and AddSchool()) method but the needed id keys don't exist yet. I spent last night poring over my brand, new copy of NHibernate in Action (I LOVE THAT BOOK!), but can't find any advice. Help!
