Read : http://book.cakephp.org/view/85/saving-related-model-data-habt
It describes the proper way to create a habtm form and save the
related data [especially the last sentence!].
Also, I'm not sure I understand about the multiple-select-box. You've
defined an assoiciation where `A` has and belongs to *many* `B`, but
you don't want the select box to be multiple? How does this work?
