Yeah, that worked, thanks :))
public Visual getRepresentation() {
Bounds b = getNodeBounds(getSelectedPath());
BufferedImage canvas = new BufferedImage(b.width, b.height,
BufferedImage.TYPE_INT_ARGB);
Graphics2D g = (Graphics2D) canvas.getGraphics();
g.translate(0, b.y * -1);
paint(g);
return new Picture(canvas);
}

I'll to reply with some example code in a couple of hours if I have
some free time.
If I remember correctly, it goes something like ...
- Create a BufferedImage to hold the representation
- Get the bounds of the node you wish to use for the representation
- Apply a transformation so that the TreeView bounds of the node align
over your BufferedImage
- Call the TreeView's paint(Graphics2D) method

- Put the BufferedImage into a Picture
http://pivot.apache.org/2.0/docs/api/org/apache/pivot/wtk/media/Picture.html
- Use the Picture as the representation

While dragging, it would also be cool to show the actual node via
DragSource#getRepresentation(). I'm unsure how to get a hold of this.

I'm sure plenty of people would be interested in what you
have done if you are willing and able to share it.
Allright, then I'll try to blog about it this coming weekend
and put up some code :) Will post here.
