Preloading form:select

[Jay Abrahm]

I have a page that first makes a DB hit for authentication and at the same time populates the jsp dropdown. I was able to make the db hit for both queries but unable to populate the dropdown. Can someone please help me figure what is wrong in the attached code.

<form:select path="department" items="${departments}" itemLabel="plantName" />

function validateAccess() {
$.getJSON("account/adminrole", { user: $('#loggedInGlobalId').val() }, function(isAdmin) {
	if (isAdmin) {
		showHideDiv(1);
	} else {
		showHideDiv(2); 
	}
});
}

@RequestMapping(value="/adminrole", method=RequestMethod.GET)
public @ResponseBody
boolean isPlantAdmin(
		@ModelAttribute("departments") List<Plant> departments,
		BindingResult result, SessionStatus status,
		@RequestParam String user) {
	boolean isAdmin = false;
	isAdmin = webctxAppUserDAO.isAdminUser(user);
	return isAdmin;
}

@ModelAttribute("departments")
public List<Plant> populateDepartments() {
	return webctxPlantDAO.findAllPlantsforUser("1");
}

Neither BindingResult nor plain target object for bean name 'department' available as request attribute

Also, if someone has some sample code to populate form:select it would be helpful.
