I think i know what you mean jet. There have actually been quite a few
articles written on the dangers of using requestAction. If I am going
to be using something like you are using, what I will usually do is
set up a function in app_controller that imports the Category model,
does a find('all') on that Category model and then sets the variable
$this->set('categories',$categories). If you don't want it on every
controller action, then you could set up an array of controllers and
actions where the function should run and then just set that up in the
beforeFilter function of the app_controller..
$controllerArray = array('Category'=>array('index'));
if(isset($controllerArray[$this->name][$this->action]){ $this-
>_setUpCategoriesNav(); }
