Question

我的页面中有两个rich:extendedDataTables。一个是“主”，另一个是“奴隶”，因为从属数据依赖于主数据。

主人为每个列设置了filterBy。我希望能够在主表中的过滤器事件上rerender从表。

我最接近成功的是试图点击下面的“Return”按键，但效果不好：

<rich:hotKey selector="#masterTableEnclosingPanel" key="return" 
    handler="doSomethingA4jFunction()" preventDefault="true" type="onkeyup" /

我正在使用RichFaces 3.3.3。任何想法都非常受欢迎！

根据汗的要求，我添加了一些XHTML源代码。我正在使用RichFaces 3.3.3：

Answer 1

解决方案是将slaveTablePanel放入reRender的{{1}}中：

masterTablePanel

问候：）

Answer 2

尝试将以下内容添加到主表：

<a4j:support event="onkeyup"
             oncomplete="myCustomFilterColumnsJSFunction()"
             reRender="slaveTablePanel" />

在另一个表的过滤器事件中重新渲染rich：extendedDataTable
