[TYPO3-mvc] Tx_Extbase_Persistence_Repository->add() does not work

Hi Alexander,

>     $this->orderItemRepository =
> &t3lib_div::makeInstance('Tx_XXX_Domain_Repository_OrderItemRepository');

Where inside the Controller is this code located? inside 
initializeAction()? I'm also not sure about the ampersand in front of 
the call - what does this mean in this case? creating a reference? 
creating by using a reference to t3lib_div. Looks strange to me - maybe 
something went wrong there.

regards
Dennis
