Hi, It is my first experience with Wicket. I try to do a e-commerce site, based on cheese shop from Wicket in Action Book. I have problem to implement shopping cart to set the quantity of each item that the user choose. As you can see in this screenshot, I put a TextField for quantity in a ListView of all items that the user put in the shopping cart. At beginning all quantity value are set to 1. The problem is that it works correctly only if I have only one item. If I have two or more items, I can set correctly only the last quantity. Foe example, If I try to set quantity of the first item, the value that will be assigned to it will be the value of the last item. Thank you for help!
