components/com_communitysurveys/views/response/tmpl/default_form.php on line 128

Versions: com_communitysurveys_v3.5.9
with cjlib v 2.0.12
Joomla 2.5.16 / php5.5.1-2

I've a survey with 3 pages:

When filling in the survey and after switching to page 2, a notice is shown:

( ! ) Notice: Undefined property: stdClass::$key in /home/tkuschel/workspace/joomla/src/components/com_communitysurveys/views/response/tmpl/default_form.php on line 128 Call Stack #TimeMemoryFunctionLocation 10.0001138280{main}( )../index.php:0 20.10293013696JSite->dispatch( )../index.php:42 30.10443061260JComponentHelper::renderComponent( )../application.php:197 40.10823120456JComponentHelper::executeComponent( )../helper.php:351 50.10823137552require_once( '/home/tkuschel/workspace/joomla/src/components/com_communitysurveys/communitysurveys.php' )../helper.php:383 60.11343223980CommunitySurveysController->execute( )../communitysurveys.php:58 70.11423252768JController->execute( )../controller.php:112 80.11423253212CommunitySurveysControllerResponse->save_response( )../controller.php:761 90.11973300644CommunitySurveysControllerResponse->display_to_survey_form( )../response.php:160 100.12193368464CommunitySurveysViewResponse->display( )../response.php:227 110.12283387348JView->display( )../view.html.php:160 120.12283387648JView->loadTemplate( )../view.php:205 130.12293405800include( '/home/tkuschel/workspace/joomla/src/components/com_communitysurveys/views/response/tmpl/default_form.php' )../view.php:649 ">

I digged into the code, and found that the object $this->item->key _does_ exist on page 1, but if you switch to page 2 the $this-item->key is gone and a message is fired!
I made a dump of the object $this-item (@page2) of my survey on a test platform (no "key"):

a var_dump($this->item) outputs:
