Hi I had the same problem, but I was using a self-referencing many-to- many relationship. The example in the documentation for this worked pretty well for me during 0.9.11 but totally crashed and burned in 0.10.0. I can't point to the link now since the datamapper.org site is apparently gone :( I have since gone back to 0.9.11, now just waiting for documentation to surface on how I can do this.
I do think some of the changes makes lots of sense in 0.10 but without documentation on how to make things work again I can't afford to stop my projects and figure it out bit by bit.
