无法在我的primeface的数据表</p：ajax>上使用<p：ajax>

标签： ajax jsf datatable jsf-2 primefaces

我在数据表的即时行选择方面遇到了一些问题，正是<p:ajax/>。它给了我这个错误：

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

所以我做了一些研究，我认为这是一个旧版本的问题，所以我已经将我的版本更新为3.0.M3-SNAPSHOT但我仍然有同样的错误，我想知道为什么！
这是我的页面代码：

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

    <p:ajax event="rowSelect" listener="#{projet.redirection}" update="formEquipe" oncomplete="projetDialog.show()" />  
        <f:facet name="header">  
            Select a row to display a message  
        </f:facet>
        <p:column headerText="Code" sortBy="#{p.projets.codeProjet}" filterBy="#{p.projets.codeProjet}">

            </h:panelGrid>  
        </p:column>             
     </p:dataTable>  
     <p:dialog header="Car Detail" widgetVar="projetDialog" resizable="false" width="200" showEffect="clip" hideEffect="fold">  
        <h:panelGrid id="display" columns="2" cellpadding="4">  
            <f:facet name="header">

            <h:outputText value="Etat:" />  
            <h:outputText value="#{projet.currentChangerStatus.etats.libelleEtat}" />

            <h:outputText value="Date Reception:" />  
            <h:outputText value="#{projet.currentChangerStatus.projets.dateReceptionProjet}" />

            <h:outputText value="Libelle" />  
            <h:outputText value="xxxx" />  

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

这是我的函数代码：

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");
}

也许我没有正确地集成Primefaces jar，所以这是我的POM（maven）：

答案 0 :(得分：2)

请勿尝试将<p:ajax>放入<p:dataTable>内。这是PrimeFaces组件之一，您可以在组件本身中声明与Ajax相关的属性。

以下是PrimeFaces文档中的一个示例：

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

       ...columns

</p:dataTable>

了解rowSelectListener

中如何正确声明<p:dataTable>属性？

您获得的错误： 父级不是ClientBehaviorHolder的实例

这意味着父标记不能包含Ajax标记。上面的例子来自PrimeFaces 2.2文档，但我相信3.0是类似的。

修改

我的错！我在家里回复，无法访问使用PrimeFaces 3.0的代码。在PF 3.0中（与PF 2.2不同），您可以嵌入<p:ajax>元素。这是一个适合我的代码示例：

<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>

以下是我的听众方法签名：

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

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

我对您的网络应用程序了解不足以了解您的重定向是如何工作的，但我还会在用户单击“注销”按钮后向您提供我在webapp中使用的代码示例，然后重定向它们到“你已登出”页面。此代码是从操作方法调用的。

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

尝试保留一罐主要表面，即2.1.1或3.1.1不是两者，它们会产生冲突。 它对我来说也是同样的错误，希望你的意志也能得到解决。

答案 2 :(得分：1)

您是否将editable=true放入数据表中？试试这个：

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