Newbie question - how to add parameters to the form

[shark]

Hi all,
When a method annotated with ModelAttribute the return data that will be bounded to a form:
@ModelAttribute("someName")
public List getSomeList(){

}

What is the correct way to access "someList" during from different method

Newbie question - how to change ModelAttribute data
say:

@RequestMapping(method = RequestMethod.GET)
public ModelAndView setUpForm(){
            ModelAndView modelAndView =  new ModelAndView("driverForm");
	modelAndView.addObject("driver",driver);
       //  change the list value here
	return modelAndView;
}
