How can I export elements in array to .xhtml
Hi all,
I'm working with simple project using JSF is: Brandi's Bagel House. Everything is OK. And now I want to present elements that the user choice like: Bagel, Topping, Coffee... onto Receipt.xhtml. But I don't know how to do because a data type of selectedToppingNames is an Array.
Please help!
Here is my code:
Index.xhtml:
<?xml version='1.0' encoding='UTF-8' ?>

This is the Result onto Index.xhtml:

Whole Wheat
Topping
Cream cheese
Butter
Peach jelly
Blueberry jam
Coffee
Regular Coffee
Decaf Coffee
Cappuccino
This is the Result onto Receipt.xhtml:
Receipt

Coffee : Regular Coffee $1.25
Subtotal : $2.75
Tax: $0.16
Total: $2.92
