Have a look in Model::__saveMulti(). I still haven't quite figured out
the logic but the HABTM model's save() is called (which would trigger
its callbacks) in some instances. But it's still a bit foggy to
myself, as well. For instance, the block beginning at line 1286
starting with:
foreach ((array)$data as $row) {
... doesn't make any sense to me at all. I can't understand how that
could work properly.
