This is just a comment that I appreciate the new behavior for naming foreign keys when you create a new association in ORMD2.
In ORMD1, it used to take the entity name and just append _id. Example
MyEntity_id
In ORMD2, you now convert that to underscore separated lower case. Example
my_entity_id
This is much better. I used to have to go in and change that every time by hand.
