Ako sa dostat v attached k presitentnemu parametru?

Caute neviete mi poradit ako sa dostanem k presistentnemu parametru komponenty v metode attached?

class FilterFormControl extends BaseFormControl
{
	/** @persistent */
	public $data;

	protected function attached($presenter)
	{
		if ($presenter instanceof Presenter) {
			$data = $this->data; // Toto mi vracia null, aj napriek tomu ze by tam malo nieco mat
		}
		parent::attached($presenter);
	}
}
