[Rails] HABTM problem not saving all associations

Hello all,

I have an Order object that has and belongs to many Products and has
and belongs to many Loan Types.  This is so I can select multiples of
each in my order entry screen via checkbox groups.

I''m having some trouble with saving multiple HABTM associations for a
single model object; only the first HABTM association declared in the
model will save during the initial @order.save in the create action in
my orders_controller.rb code below.

If the order is then updated via an edit action, all selected
associations will save correctly.  If you notice in the
development.log dump, I''m passing product_ids and loan_type_ids arrays
back to the controller properly.  Inspecting the @order object during
a breakpointer session shows the related object are available for
saving, but for some reason, ActiveRecord does not want to save the
second association class at the beginning.

Any ideas what I''m doing wrong?

I''m using Ruby 1.8.2, Rails 1.0 and MySQL 5.0.16 on both Ubuntu Breezy
and Mac OS X Tiger 10.4.3. Ruby and MySQL were built from source on
both as well.

Thanks for your time and attention.
