The following changeset ...

http://dev.rubyonrails.org/changeset/8675

breaks line 705 of lib\active_record\connection_adapters\activesalesforce_adapter.rb

belongs_to associations do not support the :nullify option as of that revision.  in fact, discussions indicate that
the :dependent option, while valid, should not be used on belongs_to associations.  see here for a discussion...

http://dev.rubyonrails.org/ticket/10592

a patch is attached.

okay.  hopefully last comment.  lines need to be concatted for
that patch to work, obviously.  there's only one line that needs
changing.

oops.  I should have titled it "defining belongs_to with
:dependent => :nullify breaks in edge rails > r8675"
