如何使用c：foreach動態創建rich：dropDownMenu？

我想動態地填充下拉菜單，所以我用<c:forEach>，但我無法看到前端的數據。如何使用c：foreach動態創建rich：dropDownMenu？

我的JSF

<rich:dropDownMenu id="drop_down" value="Add" 
      direction="bottom-right" jointPoint="auto"> 
      <c:forEach var="item" items="#{library.addLeftPanel}" > 
       <rich:menuItem submitMode="ajax" value="#{item}" 
        actionListener="#{library.populateCBConditions}" 
        reRender="tree_comp, filtab" /> 
      </c:forEach> 

</rich:dropDownMenu>

我的Managed Bean的

private List<String> addLeftPanel; 


    /** 
* @param addLeftPanel 
*   the addLeftPanel to set 
*/ 
public void setAddLeftPanel(List<String> addLeftPanel) { 
    this.addLeftPanel = addLeftPanel; 
} 

/** 
* @return the addLeftPanel 
*/ 
public List<String> getAddLeftPanel() { 
    if(null==addLeftPanel){ 
      addLeftPanel = new ArrayList<String>(); 
    addLeftPanel.add("First"); 
    addLeftPanel.add("Secound"); 
    } 
    return addLeftPanel; 
}

我使用JSF 1.1。
