Sorry if I was unclear.
A is a parent object which owns B and C children. A has a certain set of
Bs each mapped against a set of Cs. A:B is many to many. B:C is many to
many. A:C is many to many.
For the interim I am using ResultMaps to build an inner class (BC) of A,
which holds one B and a list of Cs. It works, but I would prefer to avoid
the necessity of this class, and be able to directly pass {B, C[]} to the
A bean.
Does that clarify things?
Thanks
