I have several models which all have has_and_belongs_to_many
releationships with each other. When the create action is called, the
ActiveRecord.Base#save will only save one of these relationships, the
rest will be ignored. When the update action is called the
ActiveRecord.Base#save will then save all of the relationships. Both
actions call the same method to get the values (from the multi-select
box) and populate the accociated objects. Before upgrading to 1.0 this
worked fine. After upgrading it broke. After rolling back it worked
again. Also, it is happening for all the models.

My ISP says they have not heard of this from anyone else, and no one on
irc has heard of it either?

Does anyone have any ideas?

Thanks,
