[TYPO3-mvc] pre-render partial in controller and put it in footerData?

[Gerhard Mehsel]

Hi,

I have to put some Javascript into the page footer. Is it possible to 
pre-render a partial in Extbase controller and put it to the bottom of 
the generated page with 
$GLOBALS['TSFE']->additionalFooterData['ballaballa1'] = ... or 
$this->response->addAdditionalFooterData(..)

(the later is buggy at the moment I think)


So the questions is: what's the best way to pre-render a partial for 
further use in controller?


Regards,
gerd
