I'm trying to display a shopping cart in my application (Seam/RichFaces), and have included a "remove from cart" <a4j:commandLink />
next to each item to remove the item from the cart. When I click the link it is supposed to rerender the cart contents to show that the item has been removed. However, when I click the link, nothing happens. The cart is backed by an ArrayList in my action that contains the items. I can see the call in my action, so I know the item has been removed -- and, if I refresh the page I see it has been removed. Am I doing something wrong in my code below that is causing this section of the page not to rerender properly?
UPDATE: It seems as though it will rerender properly, but not in all circumstances. If I've got more than 1 item in my cart and remove any item but the most recently added item it rerenders properly. If I only have one item in the cart, or I try and remove the most recently added item, it fails to rerender anything. Any thoughts on what's going on here??
