Hi. A visitor stores some data in his session-scoped shopping cart. I want to create GWT managing cart page. ----------- Item Name | Quantity ----------- Quantity is a text field shows the current quantity for each item. There is a submit method to update the data. A visitor can edit the quantities for the current items in his cart and press Update button to propagate those changes to his cart. Here is the question: * The application has many text fields (the number of text fields depends on the current number of items in the cart). How many text field do I need? one for each item? or just one instance? Thanks.
