actually I wonder if this works at all - I'd be surprised if you can
assign ids to a has_many :through relationship like that. However
you could try this:
@document.disable_ferret
if @document.update_attributes(params[:document])
@document.ferret_update
flash[:notice] = 'Document was successfully updated.'
redirect_to :action => 'show', :id => @document
else
render :action => 'edit'
end
end

the problem with indexing data from related objects seems to be that the
after_update hook of aaf is called too early, that is, before all
relationships are saved. Most often it helps to first save the record
(and skip the indexing, which saves some time) and index the record
after that.
cheers,
Jens
