Как создать форму с несколькими страницами на JSF с PrimeFaces

Question

Привет, я хочу кое-что спросить, я пытаюсь сделать форму для веб-сайта, используя Java с Primeface, я делаю эту форму с 2 страницами, но когда я пытаюсь ввести данные, данные со второй страницы иногда не могут быть установлены в базе данных, когда Я пытаюсь изменить код, данные на первой странице не могут быть установлены, но данные на второй странице могут быть установлены в базе данных

это мой код для сохранения данных

public String save(){
    String nextPage = "";

    PRPKUserNonIt PRPKUser = new PRPKUserNonIt();

    PRPKUser prpkUser = new PRPKUser();
    setListUserSelected(chooseBean.getListSelecteduser());

    try{
        prpkUserController.save(prpkUser);
        nextPage = "/prpk/master_prpk.xhtml?faces-redirect=true";
        RequestContext rq = RequestContext.getCurrentInstance();
        rq.execute("PF('successDialog').show();");
    }catch(Exception e){
        e.printStackTrace();
        FacesMessage messageFailed = new FacesMessage(FacesMessage.SEVERITY_ERROR,"Error","Save data failed");
        RequestContext.getCurrentInstance().showMessageInDialog(messageFailed);
        nextPage = "#";
    }


    Group group = new Group();
    setListGroupSelected(chooseTargetSDDialogBean.getGroupSelection());
    try{
        groupController.save(group);
        nextPage = "/prpk/master_prpk.xhtml?faces-redirect=true";
