I try to include custom css file for a certain page. I use `Requirements::css()` method in the PageController `init()`, but I also tried the template tag: `<% require css(mytheme/css/aa.css) %>`. The result is, there's no link to the file in generated page. There are no errors reported, just no effect. The `init()` method gets called, I can fire log from inside of it.

```
class AaPage_Controller extends Page_Controller {

    public function init () {
        parent::init();
        Requirements::css("mytheme/css/aa.css");
    }

}

```

I'm walking in circles now, could anyone with more SS experience suggest a way to debug the problem?
