version 0.5 Page 154 - 155 Larry, 1. What exactly is is a filter chain? 2. In the particular example given, does "invoking its run() method" mean invoking the "account" action's run method? 3. Where can I find the "account" action? Is it in the yii_cms? Should I search for "actionAccount" as a string within the files in the Protected folder? 4. If the "Account" action is hypothetical, would it really have a method called "run()"? If not, what is a run() method? Quoting from the book" "The method needs to take one parameter, which will be a filter chain. This variable will be used to allow the action to take place by invoking its run() method (i.e., continue the filtering and such)." The example given is: public function filterHttpsOnly($fc) { if (Yii::app()->getRequest()->getIsSecureConnection()) { $fc->run(); } else { throw new CHttpException(400, 'This page needs to be accessed securely.'); } } public function filters() { return array( 'accessControl', // account must be accessed over HTTPS: 'httpsOnly + account', ); } Thanks.

Version 0.5 Page 150 Larry, Can you please break this paragraph down or explain it another way? I've read it and re-read it numerous times. I understand the preceding and following pages, but not this paragraph and example. Thanks. "However, when you’ve identified a parameter in a rule that’s not part of the route, it will only be passed to an action if that action’s parameter is named the same. The earlier example code works, but this action definition with that same rule will throw an exception (Figure 7.1): # protected/controllers/PageController.php public function actionView($x) { // Etc."

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.
