NumberFormatException PrimeFaces TreeTable

Question

我目前正在使用Primefaces和treetables。除一例外，我的心臟起搏效果很好。讓我來一個小例子來說明這個問題：

的treetable中是這樣的：

• Item1.1
  • Item2.1
• Item1.2
• 項目1 .3

在開始時，樹是崩潰了。 的treetable中這樣定義：

<p:treeTable id="treetable" value="#{bean.root}" var="node" selectionMode="single" selection="#{bean.selectedNode}"> 

而且我在它的Ajax調用：

<p:ajax event="select" listener="#{bean.onSelect}" /> 

一切都在一般運行良好。無論節點的級別如何，所選節點都會更新。問題是這種情況：

（全部是摺疊）

1. 延長Item1.1
2. 選擇Item2.1
3. 崩潰Item1.1
4. 選擇Item1.2

在這裏，我得到了一個例外：

Answer 1

這是PrimeFaces bug中的treetable.js,there is issue。

的問題是因爲unselectAllNodes（）在treetable.js功能不明確選擇數組變量，但它應該是空的從該函數退出後：

unselectAllNodes: function() { 
    var selectedNodes = this.tbody.children('tr.ui-state-highlight'); 

    for(var i = 0; i < selectedNodes.length; i++) { 
     this.unselectNode(selectedNodes.eq(i), true); 
    } 
} 

當父行與因爲所有可見的選定行（通過ui-state-highlight屬性進行搜索）取消選擇並從選擇數組變量。但是當父行被摺疊時，tbody.children *（'tr.ui-state-highlight'）*返回空列表，並且選擇數組變量具有以前的值加上以逗號分隔的新的可選值。

從PrimeFaces 4.0版本發佈此錯誤的好消息已修復。因爲this commit已被納入發佈。一個小的區別：選擇數組變量已被其他提交重命名爲選擇。

unselectAllNodes: function() { 
    var selectedNodes = this.tbody.children('tr.ui-state-highlight'); 
    for(var i = 0; i < selectedNodes.length; i++) { 
     this.unselectNode(selectedNodes.eq(i), true); 
    } 

    this.selections = []; 
    this.writeSelections(); 
}
