[TYPO3-commerce] recalculate_item_sums() in basket

[Peter Waechtler]

hello,

i am busy implementing my own global discount option based on the  
code by franz koch: http://lists.netfielders.de/pipermail/typo3- 
project-commerce/2007-October/001218.html

every thing is working, except the recalculation of the the sums.  
when i  echo $basketItem->priceGross; i get the new gross price - yet  
the sums in the basket to not change - what am i doing wrong?

thanks,
piet

          $basketItem = $basket->basket_items[$itemId];
          $articleObj = $basketItem->article;
		
          //get prices of items

              $basketItem->priceNet = $basketItem->price- 
 >get_price_net()*9;
              $basketItem->priceGross = $basketItem->price- 
 >get_price_gross()*9;

	     //show new prices - have they been calculated?	
	     echo $basketItem->priceGross;
