如何填寫selectOneMenu用於JSF

-1

我想從我的數據的基礎上填寫的selectOneMenu用於，但始終列表爲空這是我的代碼：如何填寫selectOneMenu用於JSF

public ArrayList<String> FindListKpi(Integer userid) 
{ 
    ArrayList<String> usrpr=new ArrayList<String>(); 
    try{ 

     EntityTransaction entr=em.getTransaction(); 
     entr.begin(); 

     javax.persistence.Query multipleSelect= em.createQuery("select k.kpiName FROM ProfilUser p, Kpi k, AssociationKpiProfil a WHERE p= a.profilUser and a.kpi=k and p.profilUserId= :w"); 
    multipleSelect.setParameter("w", userid); 
    /* to tranform list to an arraylist*/ 
    List usrpro = new LinkedList(); 
    usrpro= multipleSelect.getResultList(); 
    usrpr = new ArrayList(usrpro); 

     entr.commit(); 
     System.out.println("listttttttttttttttttttttttt"+usrpr.toString()); 
    return usrpr; 
     } 
     catch (Exception e) 
     { 
     System.out.println(e.getMessage()); 
     System.out.println("error"); 
     } 
     finally { 
     em.close(); 
    } 

    return usrpr; 

}

我的功能，填補選擇框：

public List<SelectItem> getMyListKPIs() { 
FindKpi fkpi =new FindKpi(); 

if (MyListKPI == null) { 
MyListKPI = new ArrayList<SelectItem>(); 

for (String val : fkpi.FindListKpi(iduser)) { 
MyListKPI.add(new SelectItem(val)); 
} 
} 
return MyListKPI; 
}

結果： listttttttttttttttttttttttt []

我測試了我的方法「FindListKpi」，它工作正常：

public static void main(String[] args) { 
System.out.println("list"+ kpilist.FindListKpi(1)); 
}

結果：

list [Number Of Closed issues, Number Of Opened issues]

所以在方法getMyListKPIs的問題，其實誤差正是在proprity「ID用戶」，這proprity我已經通過它從另一個bean值：

<managed-bean> 
<managed-bean-name>ToolsKPI</managed-bean-name> 
<managed-bean-class>DAOKPI.ToolsKPI</managed-bean-class> 
<managed-bean-scope>session</managed-bean-scope> 
<managed-property> 
<property-name>iduser</property-name> 
<property-class>java.lang.Integer</property-class> 
<value>#{BeanTools.iduser}</value> 
</managed-property> 
</managed-bean>

你好我已經解決了這個問題的錯誤是在文件的臉，配置，我的託管proprity是錯誤的，實際上持有的屬性配置的值：

ID用戶 java.lang.Integer中＃{} BeanTools.iduser
