In Component Behaviour @ http://www.yiiframework.com/doc/guide/basics.component it says:
// $name uniquely identifies the behavior in the component
$behavior->attach($name,$component);
// test() is a method of $behavior
$component->test();
but $behavior->attach($name, $component) is public void attach(CComponent $owner)
Even so, I can’t make that work, but then $component->attachBehavior(‘some_name’, new SomeClass) makes a lot more sense to me and it works
