나는 다음과 같은 JSF보기 index.xhtml 있습니다경고 : /index.xhtml 22110 대상 = "# {menuTab.action}"@ 형 com.menu.MenuTab에 쓰기 오류 '액션'

그리고 다음과 같은 관리 빈 MenuTab.java

import java.util.Iterator;
import java.util.List;
import javax.faces.bean.ManagedBean;

@SessionScoped
public class MenuTab implements Serializable {

public MenuTab() {
}
private String action;
private String value;
private List<String> listOfObjs = new ArrayList();
public String getAction() {
return action;
}
public void setAction(String action) {
this.action = action;
addValue(action);
}
//--------------------------------------
public void addValue(String act) {
if (listOfObjs.isEmpty()) {

getListOfObjs().add(getValue());
System.out.println("First Data add First Data add First Data add::::::::::::::::" + value);
}
Iterator idvalu = listOfObjs.iterator();
while (idvalu.hasNext()) {
System.out.println("aaaaaaaaaaa=====" + idvalu.next());
value=act;
if (idvalu.next().equals(value)) {
System.out.println("Data Alrady Exite Data =====" + value);
}
else {
setValue(act);
getListOfObjs().add(getValue());
System.out.println("bbbbbbbbbbbbbbb=====" + value);

}
}
/**

public List<String> getListOfObjs() {
