No, I know how to write Jvascript to do my own validation, that is not a problem. I am trying to use the Struts 2 client side validation to do this for me. That is one of the benefits of the Struts 2 validation framework - you can simply define a form element as 'required' and struts handles all the client side validation for you. I just want to know if it is possible to do this for a <s:scheckboxlist element ...
