visibility of property set in #PostConstruct in ManagedBean - jsf

Question

i am tryiing to get property value in my #RequestScoped Bean which is set in #PostConstruct. I have editUser page witch get userId from other page, and i am getting user from database in #PostConstruct, but when i try to edit that user in same page, user object is null, in method editUser.
Is there a way to get that object, which is set in PostConstruct?
Here is my EditUserBean:
package ba.nedim.colaborationtoolapp.model;
import ba.nedim.colaborationtoolapp.dto.UserDTO;
import ba.nedim.colaborationtoolapp.services.RegisterService;
import java.io.Serializable;
import javax.annotation.PostConstruct;
import javax.annotation.PreDestroy;
import javax.ejb.EJB;
import javax.faces.bean.ManagedBean;
import javax.faces.bean.ManagedProperty;
import javax.faces.bean.RequestScoped;
import org.primefaces.json.JSONObject;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
#ManagedBean
#RequestScoped
public class EditUserBean implements Serializable{
#EJB
private RegisterService userService;
private final Logger log = LoggerFactory.getLogger(EditUserBean.class);
private int idUser;
#ManagedProperty("#{param.id}")
private int actionId;
public int getActionId() {
return actionId;
}
public void setActionId(int actionId) {
this.actionId = actionId;
}
private UserDTO user = new UserDTO();
public UserDTO getUser() {
return user;
}
public void setUser(UserDTO user) {
this.user = user;
}
#PostConstruct
private void initialize(){
if(actionId!=0){
setUser(userService.getUserByID(actionId));
}
}
public void editUser(){
UserDTO user = getUser();
log.info("UserID:" + user.getIdusers());
}
private String gotoUserPage(){
return "users";
}
}

After the page has been fully rendered, the #RequestScoped bean is destroyed along with all its instance variables (including the user). I presume this is the point at which you then attempt to execute editUser() which results in an NPE.
Use a #ViewScoped bean instead, to ensure your instance variables survive a postback to the same view
