  1. Larry, on page 150 of the YiiBook2 (latest version), you write that the following code is "verbose, redundant, and illogical": $model = new Page(); $model = $model->findOne($id); Instead of creating an instance of the Page class, as shown above, you say we should use a static class instance (or static method?), like this: if (($model = Page::findOne($id)) !== null) { return $model; etc. I don't understand why the first example is "verbose, redundant, and illogical", and why the second example is preferred. Can you please explain this? Thanks.
  2. Version 0.5 Two questions about page 115. 1. Quoting from the book: "<?php $this->pageTitle = Yii::app()->name . '::' . $model->title; ?>" Why are there two colons before $model->title ? I assume they will appear literally, but maybe they function as code -- I'm not sure. 2. Quoting from the book again: "{TIP} Because the page title is set by assigning a value to the controller instance, it can also be set within the controller action, if you’d rather." This sentence is saying 2 things, neither of which I understand. Larry, can you please break this down and provide an example? Thanks.
