TYPO3 Core

I may add that with a N-M relation it renders N, then renders the dependent M, then again renders backward the dependent N. So with the 2nd N to render it may have already rendered all N before. The "see above" would be ok then.

But still I don't understand why there is a difference between rendering the below view vars:

$this->view->assign('objects', array('akey' => $objects));  // does not work
$this->view->assign('objects', array('a2ndkey' => array('akey' => $objects)));  // does work

Please confirm whether this also happens if you use DebuggerUtility::var_dump from your controller action. The DebugViewHelper is just a shell around this utility.

If it also happens there: please move this question to the "Extbase" category.

If it does not happen there: please include further details about the statement you use to debug your variables, how you pass your variables etc.

For bonus points please try this on the current git master of TYPO3.CMS (which passes variables slightly differently from the 7.6 LTS fluid).
