Problem
Need a simple and easy to understand solution for creating a Shopping Cart in Flex. The app would allow to ADD to the cart and REMOVE from the cart. Also, the quantity should increment when an existing item has been added. Line totals should be calculated, and also a grand total for the cart. Looking for the cleanest and most optimal way of doing this.
Solution
I'm not sure that this is the best solution or this solution is covering all your needs. But its a good point to start from. I can made some customization and improvement of my code, if this will be needed.
