过滤后的 Primefaces 5 复选框多选错误答案

【问题标题】：Primefaces 5 Checkbox Multiselect Bug after Filtering过滤后的 Primefaces 5 复选框多选错误
【发布时间】：2014-09-03 20:26:11
【问题描述】：

我在 Wildfly 8.0.0 上使用 Primefaces 5 和 Primefaces Extension 2.0.0 和 JSF 2.2。

我使用frozenColumns、过滤、分页以及内置复选框提供的多选实现了一个数据表。

在大多数情况下，Selected Items 已提交，但在以下示例中不提交：

未选择任何项目
使用任何过滤器字段过滤数据表内容
选择项目
提交表格 -> 未提交所选项目

【问题讨论】：

添加rowKey属性有帮助吗？
我在添加适当的rowKey参数后再次尝试->仍然不起作用

标签： primefaces datatable multi-select

【解决方案1】：

我找到了所描述错误的来源：带有 freezeColumns 的数据表的 Javascript 对象提供了一个函数来复制由 ajax 请求（如排序、过滤器等）接收的 's。此函数不处理保存在 .

的数据 (jQuery data()) 中的 'rk' 值

原文：

copyRow: function(original) {
    return $('<tr></tr>').data('ri', original.data('ri')).addClass(original.attr('class')).attr('role', 'row');
};

我的解决方法：

PF(datatableUtils.datatableWidgetVar).copyRow = function(original) {
    return $('<tr></tr>').attr('data-ri', original.data('ri')).attr('data-rk', original.data('rk')).addClass(original.attr('class')).attr('role', 'row');
};

使用 attr() 和“data-”前缀写入数据是必要的，因为它似乎丢失了存储的数据，因为 tr 尚未附加。（老实说，我没有坚持到最后，如果我错了，请纠正我）
