[TYPO3-mvc] PHP Error: 'Tx_Fluid_Core_ParsingException'

[Steffen Ritter]

Hey folks,
I'm encountering an error I do not know how to handle

<b>Fatal error</b>:  Uncaught exception 'Tx_Fluid_Core_ParsingException' 
with message 'could not determine type of argument &quot;each&quot; of 
the render-method in ViewHelper 
&quot;Tx_Fluid_ViewHelpers_ForViewHelper&quot;. Either the methods 
docComment is invalid or some PHP optimizer strips off comments.' in 
/SERVER/typo3/trunk/typo3/sysext/fluid/Classes/Core/AbstractViewHelper.php:213

My Template simply consists of

<h1>Strassenliste</h1>
<ul>
	<f:for each="streetIndexes" as="streetIndex"><li>a</li></f:for>
</ul>


Index action only does:
public function indexAction() {
	$this->view->assign('streetIndexes', $this->streetRepository->findAll());
}

Anyone knowing this?

regards

Steffen
