無法查看primefaces樹

我是JSF新手，所以這是我的第一個項目。我的IDE是netbeans的7.0.1，2.1.1鑽嘴魚科和primefaces 2.2.1無法查看primefaces樹

我通過http://www.primefaces.org/showcase/ui/tree.jsf 使用的樹例子，而我設法用其他faclets從素（例如號碼：按鈕）的樹不爲我工作（空白屏幕）有人可以請我解釋我做錯了什麼？

感謝

} 

public TreeNode getRoot() { 
    return root; 
}

}

我想這是因爲你沒有@ManagedBean標註在TreeBean類
