My form has two sections A and B. Section A is a drop down list. When users select a value from drop down list, it will perform Ajax call to retrieve section 2 (which contains label and text box..) However, when I submit the form, only values in section A are bounded and passed to the controller. Section B is not. My commandClass contains all get and set for both section A and B.

How do you make both section A and B bound to the form?

I use spring 3, annotation style and jquery (ajax call)

Thank again
