NumberFormatException PrimeFaces TreeTable

Question

我目前正在使用Primefaces和treetables。除一例外，我的心脏起搏效果很好。让我来一个小例子来说明这个问题：

的treetable中是这样的：

• Item1.1
  • Item2.1
• Item1.2
• 项目1 .3

在开始时，树是崩溃了。 的treetable中这样定义：

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

而且我在它的Ajax调用：

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

一切都在一般运行良好。无论节点的级别如何，所选节点都会更新。问题是这种情况：

（全部是折叠）

1. 延长Item1.1
2. 选择Item2.1
3. 崩溃Item1.1
4. 选择Item1.2

在这里，我得到了一个例外：

Answer 1

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

的问题是因为unselectAllNodes（）在treetable.js功能不明确选择数组变量，但它应该是空的从该函数退出后：

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); 
    } 
} 

当父行与因为所有可见的选定行（通过ui-state-highlight属性进行搜索）取消选择并从选择数组变量。但是当父行被折叠时，tbody.children *（'tr.ui-state-highlight'）*返回空列表，并且选择数组变量具有以前的值加上以逗号分隔的新的可选值。

从PrimeFaces 4.0版本发布此错误的好消息已修复。因为this commit已被纳入发布。一个小的区别：选择数组变量已被其他提交重命名为选择。

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(); 
}
