我有一些问题，数据表的即时行选择，完全＆LT;电话号码：AJAX /＆GT; 。它给我这个错误：

I'm having some problems with datatable's instant row selection, exactly <p:ajax/>. It's giving me this error:

<p:ajax> Parent not an instance of ClientBehaviorHolder:
org.primefaces.component.datatable.DataTable

所以，我做了一些研究，我认为这是一个老版本的一个问题，所以我已经更新了我的版本3.0.M3-快照，但我还是同样的错误，我不知道为什么！ 这里是我的网页code：

So I did some research and I think it's a problem with an old version, so I've updated my version to 3.0.M3-SNAPSHOT but I have still the same error and I wonder why! Here is my page code:

<p:dataTable id="projets"  var="p" value="#{projet.init()}" selection="#{projet.currentChangerStatus}" selectionMode="single">

            <h:outputText value="xxxx" />  
        </h:panelGrid>  
    </p:dialog>     

下面是我的函数的code：

Here is my function's code:

public void redirection(SelectEvent event) throws Exception {
    System.out.println("some message: " );
    currentChangerStatus=(ChangerStatus)event.getObject();
    currentProjet=currentChangerStatus.getProjets();
    System.out.println("le projet est  : " +currentProjet.getLibelle());
    FacesContext.getCurrentInstance().getExternalContext().redirect("infoprojet.xhtml");
}

也许我并没有集成在Primefaces罐子正确的，所以这里是我的 POM （Maven的）：

Maybe I didn't integrated the Primefaces jar correctly, so here is my POM (maven):

推荐答案

不要试图把＆LT;电话号码：AJAX＆GT; 中的＆LT;电话号码：dataTable的＆GT; 。这是PrimeFaces组件，您声明Ajax相关的属性，就在组件本身之一。

Don't try to put a <p:ajax> inside the the <p:dataTable>. This is one of the PrimeFaces components where you declare the Ajax-related attributes right in the component itself.

下面是从PrimeFaces文档的例子：

Here is an example from the PrimeFaces documentation:

<p:dataTable 
    var="car" 
    value="#{carBean.cars}" 
    selectionMode="single"
    selection="#{carBean.selectedCar}"
    onRowSelectUpdate="carListForm:dialogContent"
    rowSelectListener="#{carBean.onCarSelect}">

       ...columns

</p:dataTable>

请参阅如何使用 rowSelectListener 属性声明的权利在＆LT;电话号码：？dataTable的＆GT;

See how the rowSelectListener attribute is declared right inside the <p:dataTable>?

您是正的错误： ClientBehaviorHolder的父母不是一个实例的

这意味着父标签不能包含一个Ajax标签。上面的例子是从PrimeFaces 2.2的文档，但我相信3.0是相似的。

This means that the parent tag cannot contain an Ajax tag. The example above is from the PrimeFaces 2.2 documentation, but I believe 3.0 is similar.

编辑：

我的错误！我从家里说，并没有访问我的使用PrimeFaces 3.0 code。在PF 3.0（不像PF 2.2），你可以嵌入＆LT;电话号码：AJAX＆GT; 元素。这里是一个code样对我的作品：

My mistake! I replied from home and didn't have access to my code that uses PrimeFaces 3.0. In PF 3.0 (unlike PF 2.2) you can embed the <p:ajax> element. Here is a code sample that works for me:

<p:dataTable
        id="myDataTable"
        value="#{myBean.rowObjectList}
        var="rowObject"
        selection="#{myBean.selectedRowObject}"
        selectionMode="single">

    <p:ajax
        event="rowSelect"
        listener="#{myBean.onRowSelect}"
        update="someElement" />
    <p:ajax
        event="rowUnselect"
        listener="#{myBean.onRowUnselect}"
        update="someElement" />



</p:dataTable>

下面是我的监听器方法签名：

Here are my listener methods signatures:

public void onRowSelect(SelectEvent event) {
    // your code here...
}

public void onRowUnselect(UnselectEvent event) {
    // your code here...
}

我不知道足够了解你的Web应用程序，以了解您的重定向是如何为了工作，但我也会给你的用户之后，我使用我的webapp一个code样品点击一个退出按钮和我重定向到一个您已注销页面。这code是从操作方法中调用。

I don't know enough about your webapp to understand how your redirect is meant to work, but I will also give you a code sample that I'm using in my webapp after the user clicks a Logout button and I redirect them to a "you are logged out" page. This code is called from an action method.

FacesContext ctx = FacesContext.getCurrentInstance();
ExternalContext ectx = ctx.getExternalContext();
ServletContext sc = (ServletContext) ectx.getContext();
ectx.redirect("http://somedomain.org/somepage.html");
