I am populating the options in select list B from the option selected in select list A, when a button is clicked. When a new option is selected in select list A, I want the previous option in select list B to be deselected. The value for these select lists is being stored in the session. I have been trying to write a javascript function that I would set the onchange attribute to to do this but nothing I try is working. I dont really know javascript either. I was wondering if there is a way that I can call a method from my action class to achieve this. Is there a way to set the onchange attribute to a url that will call a method in my action class? Or is there another way I can get this to work.
Thanks!
