My name is Alexander Sabolic. I work for a german company called Nuveon Service.
We need someone to adapt virtuemart´s cart. We are generating products by ourselfs und put them into a new table similar to virtuemarts own database-cart. However, the online-cart is not effected by this, of course. We think a possible solution for us could be a change in the online-cart behavior, so that the online-cart is ONLY refreshed when the user clicks on the cart-symbol. By this, the cart has to be "filled" with the data from our own database-cart.
