Edit form without data

[zed420]

All I needed there was <form:hidden path="conId"/> and it's all working fine.

Hi All
Can someone please point me to the right direction, I'm trying to edit a form information. The form displays but it's Empty. Why ??

<form:form id="myForm" modelAttribute="contacts" method="Post" action="contacts.html" commandName="contacts">

			<label>First Name<span class="small">Edit your first name</span></label>
			<form:input path="firstName" /><br>
			<form:errors path="firstName" cssClass="error" /><br>

			<label>Last Name<span class="small">Edit your last name</span></label>
			<form:input path="lastName" /><br>
			<form:errors path="lastName" cssClass="error" /><br>

			<button type="submit">Amend</button>
		</form:form>

protected static final String EDIT_VIEW_KEY = "editForm";
	
	@Autowired
	private ContactsService conService;
	
	@RequestMapping(value="/edit/{id}", method = RequestMethod.GET)
	public String showEditForm(@PathVariable("id") Integer id,
			@ModelAttribute("contacts") Contacts contacts,Model model){
		
		model.addAttribute("contacts", contacts);
		return EDIT_VIEW_KEY;
	}

I'm not sure if I need to use a query in controller in order to get the result I have tried it like so but I get an error.

protected static final String EDIT_VIEW_KEY = "editForm";
	
	@Autowired
	private ContactsService conService;
	
	@RequestMapping(value="/edit/{id}", method = RequestMethod.GET)
	public String showEditForm(@PathVariable("id") Integer id,
			@ModelAttribute("contacts") Contacts contacts,Model model){
		
		model.addAttribute("contacts", conService.listContactsById(id));
		return EDIT_VIEW_KEY;
	}

Many thanks
