I'm trying to wrap my head around Lift, so I began reading the book. First off, way to go. This is the only complete and accessible lift introduction that I've found on the internet.
However, I found myself lost during the Pocket Change chapter (Chapter 2). I was trying to develop alongside the example, which was a failing proposition because a fair amount of code necessary to make the project compile was not there! For example, the code for the Account model object references these symbols AccountAdmin and AccountViewer which are never implemented, brought up again, or explained during the entire rest of the book.
Only by looking at the git source was I able to make the model compile and continue to code alongside the tutorial.
