I had been using the default app controller, and now, following the examples in 
the Authentication section of the book...

http://book.cakephp.org/view/1250/Authentication

...I added an app_controller.php to my project and put this into it:


<?php
class AppController extends Controller {
    var $components = array('Auth');
}


And my flash messages stopped working:


Notice: Undefined property: FooController::$Session 
[APP/controllers/foo_controller.php, line 43]
Fatal error: Call to a member function setFlash() on a non-object in 
/path/to/app/controllers/foo_controller.php on line 43


The documentation for $components says:


http://book.cakephp.org/view/961/components-helpers-and-uses

"The Html, Form, and Session Helpers are always available by default, as is the 
SessionComponent" however this appears to be false. Everything went back to 
working as soon as I changed my app_controller.php to:


<?php
class AppController extends Controller {
    var $components = array('Auth', 'Session');
}


So is the documentation wrong about SessionComponent always being available, or 
am I doing something wrong?
