Change path in PathView with NumberAnimation of its items

[herolover]

I have a PathView with Rectangle as the delegate. I change the PathView.path to another path and I want to play animation of moving PathView items to their new positions. Something like this:

PathView {
  id: pathView
  delegate: Rectangle {
    Behavior on x {
      NumberAnimation {
        duration: 5000
      }
    }
  }

  path: path1
}

But it doesn't work. Is it possible to do somehow?
