Preselect dropdown using thymeleaf

[liz Duapa]

I have no problem populating the value of my dropdown, the issue is that I cannot preselect the value based on the search I made in the database.

My Thymeleaf:

<form class="form-narrow form-horizontal" method="post" th:action="@{/userdetails/} + *{username}" th:object="${userdetailform}">
    <!--/* Show general error message when form contains errors */-->
    <th:block th:if="${#fields.hasErrors('${userdetailform.*}')}">
        <div th:replace="fragments/alert :: alert (type='danger', message='Form contains errors. Please try again.')">Alert</div>
    </th:block>

<fieldset>
  <div class="form-group" th:classappend="${#fields.hasErrors('status')}? 'has-error'">
            <label for="status" class="col-lg-2 control-label">Status</label>
            <div class="col-lg-10">
            	<select class="form-control" aria-describedby="status-addon" id="inputstatus" name="status" th:field="*{status}">					
				 <option th:each="enumStatus : ${listStatus}"
				 			th:value="${enumStatus.code}" 
				 			th:text="#{${enumStatus.value}}">Status</option>	
				</select>
            </div>
      </div> 
 </fieldset>
</form>

My Controller:

private static final String ACCNTSEARCH_MODEL_ACCNTSTATUS_KEY = "listStatus";
	private static final String ACCNTDETAIL_MODEL_ATTRIB_KEY = "userdetailform";

@RequestMapping(value = "userdetails/{username}") //to be called.
	@PreAuthorize("hasRole('ROLE_USER')")
	public String getAccounts(@PathVariable String username, Model model) {
		
		
		if(!model.containsAttribute(ACCNTDETAIL_MODEL_ATTRIB_KEY)) {
			Account accountDetail = rsAccountDetailsService.loadAccountByUserName(username);
			model.addAttribute(ACCNTSEARCH_MODEL_ACCNTSTATUS_KEY, AccountDetailsStatus.values());
			model.addAttribute("userdetailform",accountDetail);
		}
		
		return "account/userdetails";
		
	}

Just to add:

I am using Enum also:

public enum AccountDetailsStatus {
	ACTIVE(0, "status.active"),
	EXPIRED(2, "status.expired"),
	LOCKED(3, "status.locked");
	
	private int code;
	private String value;
	
	private final static class BootstrapSingleton {
		public static final Map<String, AccountDetailsStatus> lookupByValue = new HashMap<String, AccountDetailsStatus>();
		public static final Map<Integer, AccountDetailsStatus> lookupByCode = new HashMap<Integer, AccountDetailsStatus>();

	}
	
	AccountDetailsStatus(int code, String value) {
		this.code = code;
		this.value = value;
		BootstrapSingleton.lookupByValue.put(value, this);
		BootstrapSingleton.lookupByCode.put(new Integer(code), this);
		
	}
	
	public int getCode() {
		return code;
	}

	
	public String getValue() {
		return value;
	}
