[mvc2inaction-discuss] Sequence and Class Diagrams

[EM]

First of all, I bought your book through MEAP; Great book!

I have been looking for a good set of Sequence and Class diagrams
which could help me understand how the MVC parts fit together. The
only ones I have found so far are here:
http://www.codeproject.com/KB/architecture/ModelViewController.aspx

Which are very old. My questions are:

How different is the MVC2 implementation from the sequence diagrams in
that post?
Do you have a sequence diagram that shows the interaction of AJAX
inside MVC?

Thanks
