Component/s: ORM
Affects Version/s: None
Fix Version/s: 2.2.0.release

 Description  « Hide
A minority interest situation is where the user has

class A

class B
    A a;

and wants to map the relation using a join table. This is effectively an N-1 uni via join table (no collection present). We need to be able to
1. generate the schema of the join table and its respective indices/FKs
2. do inserts (from InsertRequest/UpdateRequest)
3. do fetches (from FetchRequest)
4. do updates/deletes (from UpdateRequest/DeleteRequest)

SVN trunk now generates the schema (join table), does inserts, and also fetches the related object
