Ajax – problem s headers

Ahoj,
pracuju ted se snippetama – a az do teto chvile vsecko krasne fungovalo.

Mam presenter:

<?php
class ArticlesPresenter extends BasePresenter{

	// ajax data container
	private $_ajaxData = array();
	// article container
	private $_article;


	// default render, review of last articles
	public function renderDefault() {
		$this->template->title = $this->_title . "Hlavní strana";
// vytahnuti clanku je v BasePresenteru - pouzivaji se v kazdem requestu
	}


	/*
	 * detail of article
	 * @param string $url
	*/
	public function actionDetail($url) {
		$this->_article = ArticlesTable::getArticleByParams(array('url' => $url), true); // musi se volat pred handleAddcomment, kvuli zjisteni id clanku
		if(!$this->_article) {
			throw new BadRequestException('Článek s adresou ' . $url . ' neexistuje!');
		}

		$this->_ajaxData['article_id'] = $this->_article->id;
	}

	public function renderDetail($url) {
		$this->_article = ArticlesTable::getArticleByParams(array('url' => $url), true); // duplicita v kodu s radkem 30, musi se volat po handleAddcomment, protoze stranka obsahuje nova data (uz jina nez pri actionDetail)

		$this->template->tags = ArticlesTagsTable::getTagsByArticles($this->_article->id);
		$this->template->article = $this->_article;
		$this->template->title = $this->_title . $this->_article->header;
		$this->template->heading = $this->_article->header;
		$this->template->comments = ArticlesCommentsTable::getCommentsByParams(array('url' => $url));
	}

	protected function _init() {
		$this->template->activeMenu = 'home';
	}


	/*
	* Adds a shout to the shoutbox via ajax
	* @param string text
	*/
	public function handleAddshout($text) {
		$user = Environment::getUser();

		if ($user->isAuthenticated()) {
			if (!empty($text)) {
				$data = array(
					'message' => $text,
					'datetime_created' => dibi::datetime(),
					'user_id' => $user->getIdentity()->id
				);

				ShoutboxTable::addShout($data);

				// invalidate
				$this->invalidateControl('shoutbox');
			} else {
				$this->flashMessage('Text vzkazu nemůže být prázdný!');
			}
		} else {
			$this->flashMessage('Vzkaz nebyl přidán - prosím přihlašte se.', 'error');
		}
	}
}
?>

Pokud jsem v detailu clanku, tak handleAddshout($text) funguje jak ma, invaliduje jeden snippet a vrati ho v JSONu.

Pokud jsem v renderDefault(), tak novy vzkaz („shout“) se prida, ale snippety se neinvaliduji, ve firebugu mi prijde chyba:

Cannot send header after HTTP headers have been sent (output started at /Users/michalsevcik/Sites/web/app/temp/c-Nette.Template/_f83c6f8d0c07ce8fa6955d47f2bba317.default.phtml.php:16)

Na tomhle radku je akorat echo – ale to je v detail.phtml taky, a nerve to. Jedineho rozdilu, ktereho jsem si vsiml je, ze v cachovane detail.phtml je nahore

if (SnippetHelper::$outputAllowed) { ?>

a to v default.phtml neni.

Muze mi prosim nekdo dat voditko k chybe?

Diky za Vas cas
