TYPO3.Flow

consider the following scenario:

 1 class SampleViewHelper extends \TYPO3\Fluid\Core\Widget\AbstractWidgetViewHelper {
 2 
 3     /**
 4      * @var bool
 5      */
 6     protected $ajaxWidget = TRUE;
 7 
 8     /**
 9      * @FLOW3\Inject
10      * @var ...\ViewHelpers\Widget\Controller\SampleController
11      */
12     protected $controller;
13 
14     /**
15      * @return array
16      */
17     protected function getWidgetConfiguration() {
18         $something = new \AnEntity();
19 
20 ...
21 

and

 1 class AnEntity {
 2 
 3     /**
 4      * @FLOW3\Inject
 5      * @var \TYPO3\FLOW3\Security\Context
 6      */
 7     protected $securityContext;
 8 
 9     /**
10      */
11     public function initializeObject() {
12         $this->securityContext->getParty();
13 
14 ...

the Session implementation crashes; concretely the following error occurs:

#1: Warning: session_write_close(): Failed to write session data (files). Please verify that the current setting of session.save_path is correct (/var/www/Data/Temporary/Development/Sessions) in /var/www/Data/Temporary/Development/Cache/Code/FLOW3_Object_Classes/TYPO3_FLOW3_Session_PhpSession_Original.php line 332
