Thanks, that worked.
The reason I'm updating attributes in this "complicated" way is that
I've overridden the credentials= assign method, so that I can handle
CUD (create, update, delete) operations on the association from the
same form w/o special-casing in the controller. The controller just
calls
@user.attributes = params[:user]
@user.save!
rescue
...
Thanks,
Wolf
