Answer:
You can't change the drop down with scaffolding. "It uses
generateList to get the listing - so there is no way with scaffoling -
to tell it to exclude the current item." said ChrisPartridge on IRC.
You can apply some extra validation to the model with function
beforeValidate() { if($this->data[$this->name][$this->primaryKey])
{ if($this->data[$this->name][$this->primaryKey] == $this->data[$this-
>name]['parent_id']) { $this->invalidate('parent_id'); } } }.
Also said Chris,
