[Seaside] Newbie question Seaside book.

[José Perez]

Basically in the initial (chapter 11) shows how to build a list of
contacts, and edit them, in a different page 1 by 1. Then it shows how
to handle the answer, if the user presses "save" or "cancel".

What it does is editing a "copy" of the contact, and if the user
presses "save", then the copy replaces the original contact. If
"cancel" does nothing.

In chapter 12 it shows how to "embed" an editor under the list.
Editing the contact in the same page.., and it works..., but editing
the "actual" contact. So, if you press save or cancel, the contact is
always updated...

There it is where I tried to implement the same "behavior" for the
"cancel" button...
