Well, I found a way to implement another controller hook that is
called between initialization of components and execution of action
logic:
<?php
/**
* Enables another hook (_afterComponentsInitialization()) that is placed
* between the initialization of components and the execution of action logic.
*
* So the new sequence is:
* - beforeFilter()
* - initialization of components
* - _afterComponentsInitialization()
* - action logic
* - beforeRender()
* - rendering logic
* - afterFilter()
*
* To work properly, AfterComponentsInitializationFilter needs to be the last
* Item in the $components array:
*
* class AppController extends Controller {
* var $components = array(
* 'SomeComponent',
* 'AnotherComponent',
* 'AfterComponentsInitializationFilter'
* );
*
* function _afterComponentsInitialization() {
* // Do something between initialization of components and action logic!
* }
* }
*/
class AfterComponentsInitializationFilterComponent extends Object {
function startup(&$Controller) {
$Controller->_afterComponentsInitialization();
}
}
You think this is a good way? :-)
