我有一个数据表，我加载一个模态编辑数据。但是当我编辑和渲染数据表时，没有任何变化。
我的意思是我有一个数据表和操作，如删除和编辑。当我按下编辑我打开模态，然后我编辑这个模态上的数据，然后按下编辑。如你所见，我为datatable设置了render但是我看不到datatable

错误在这里:
<f:ajax render=":branchesForm:branchesListDiv,:branchesForm:branchEditArea, @this" ... />
<f:ajax>的render和execute属性以空格分隔，不以逗号分隔。
<f:ajax render=":branchesForm:branchesListDiv :branchesForm:branchEditArea @this" ... />
正常情况下，这应该抛出一个异常详细在这个问题& & &;A如何找出客户端ID的组件ajax更新/渲染?找不到带有表达式"foo"的组件引用自"bar"，但从Mojarra 2.2.5开始，为了支持引用特定的<ui:repeat>迭代轮(issue-2958)，它停止验证这些属性。规范问题1372开始解决这个令人讨厌的快速修复并恢复验证。
逗号分隔只支持在PrimeFaces <p:ajax>中，这很可能是你困惑的地方。它支持空格和逗号分隔。强烈建议而不是在<p:ajax>中使用逗号分隔，因为从长远来看，它只会让你回到<f:ajax>时感到困惑。
