Rails - Oct 2005 - Association build question.

I found this behavior while using acts_as_tree but it applies to all 
models using has_many and belongs_to.


The problem is shown when trying to build a tree.

class Category < ActiveRecord::Base
   acts_as_tree
end



root = Category.build("name" => "root")
child1    = root.children.build("name" => "child1")
subchild1 = child1.children.build("name" => "subchild1")


child1.root # => subchild1

This happens because when building a child1 the child1.parent is not set 
to root. Thus child1.has_parent? is false.

Is this the designed behavior, or is it a bug?

Thanks,

Charles
