I've added some info below. John and I will talk more tomorrow and we'll provide more details soon.

Many-to-one on a foreign key is working. I thought I was done with unidirectional one-to-many on a foreign key (no join table), but found some bugs. I'm wrapping those up currently, then moving to bidirectional one-to-many/many-to-one. AFIK, no associations using a join table are not implemented yet. > > 1.5 id binding > > 1.6 secondary table / join table binding ? > > I did identifier binding quite some time ago.
