Rails - Feb 2008 - How to make copy of tree node?

Hi guys,

I''m working with betternestedset and need to make copy of any node,
for example:

  root
    |_ Child 1
      |_ Child 1.1
      |_ Child 1.2
    |_ Child 2
      |_ Child 2.1
      |_ Child 2.2

  root2
    |_ Child 1
      |_ Child 1.1
      |_ Child 1.2
    |_ Child 2
      |_ Child 2.1
      |_ Child 2.2

And user should copy root2 and get the result like:
  root
    |_ Child 1
      |_ Child 1.1
      |_ Child 1.2
    |_ Child 2
      |_ Child 2.1
      |_ Child 2.2

  root2
    |_ Child 1
      |_ Child 1.1
      |_ Child 1.2
    |_ Child 2
      |_ Child 2.1
      |_ Child 2.2
  copy of root2
    |_ copy of Child 1
      |_ copy of Child 1.1
      |_ copy of Child 1.2
    |_ copy of Child 2
      |_ copy of Child 2.1
      |_ copy of Child 2.2


Thanks for any help!
