Vista - Command pattern

Hi all!

For the app I am building
(http://blogs.infosupport.com/ernow/articles/3603.aspx) I am currently
pondering the editing of the 3D model part.
One of the features I want to add is an Undo/Redo option for the user.

I read some articles on implementing such a feature by extending the Command
pattern.

Now, WPF has an implementation of this pattern (System.Windows.Input) and
I'm using it already.

So here's my question: how do I add the Undo/Redo in an orderly way?

One of the things I have considered is extending the CommandManager but:
1. how do I get my window to use it
2. it is sealed...

Any suggestions?

I think I found a solution. You can download it from my blog:
