Title: SV: EJB 2.0 CMP features of Orion

One more thing,
currently, you need to add the object on each end of the bidirectional 1-n relation.


Finders are automatically generated for simple expressions, such as
findByCustomer, findbyId etc
but does not handle
findByCustomerAndId
etc.
And Im happy that more time is *not* spent on handling findByThisAndThat etc, as atleast I gonna rely on EJB QL as soon as its implemented.
