re-ordering doesnt work for newly created pages

[gerrit]

When creating new pages after the extension has been installed, the position of the new page is set to nil. This creates a problem when dragging a second child up in front of the first one
With the initial page tree like this:

parent
  -child 1 (position: nil)
  -child 2 (position: nil)

Dragging child2 above child1 leads to the following, wrong, result (radiant-drag-order revision cb30fad, radiant 0.8.1):

parent
  -child 1 (position: nil)
  -child 2 (position: -1)

I am also having issues with reordering pages. I drag them and drop them at the new location, but after the page refreshes the prescribed order is not in effect.

I am using Radiant 0.8.1.
