这是豆子

    public void onCellEdit(CellEditEvent event) {  
        Object oldValue = event.getOldValue();  
        Object newValue = event.getNewValue();  
          System.out.println("////////////////////////);
        if(newValue != null && !newValue.equals(oldValue)) {  

            DataTable s = (DataTable) event.getSource();
            Matpilotaccess1 d = (Matpilotaccess1) s.getRowData();

            articleDAO.Updatetable(d);

            FacesMessage msg = new FacesMessage(FacesMessage.SEVERITY_INFO, "Cell Changed", "Old: " + oldValue + ", New:" + newValue);  
            FacesContext.getCurrentInstance().addMessage(null, msg);  
        }  
    } ///// getters and setters 

这里的问题是连//////////////////都没有显示，这意味着HTML代码中存在问题，阻止了onCellEdit函数的执行！！！

Answer 1

我认为您只有一个问题：您的代码没有调用您的articleBean.onCelleDit（）方法。

下面是我的简单代码，它工作得很好（但我没有将richfaces组件与primefaces混合）：

<h:form id="testForm">
            <p:growl id="messages" showDetail="true"/>
            <p:outputPanel id="testContainer">
            <p:dataTable id="testTable" value="#{tableBean.data}" var="entry" editable="true" editMode="cell">

                    <p:ajax event="cellEdit" listener="#{tableBean.onCellEdit}" process="@this" update=":testForm:messages"/>
(...)

用户在表中编辑后会正确显示该消息。请尝试将richfaces面板替换为primefaces面板可能会出现此问题。

如果在p：ajax中有一些更新问题，可以使用RemoteCommand。但在这种情况下,您需要重新设计articlesbean中的方法,以便：

public void onCellEdit() {
//do some thing

<p:remoteCommand name="onCellEdit" action="#{articlesbean.onCellEdit()}" update=":form:messages" />
<p:dataTable id="cars" var="car" value="#{articlesbean.LMatpilotaccess1}" editable="true" editMode="cell" widgetVar="carsTable">  

        (...)

  <p:ajax event="cellEdit" oncomplete="onCellEdit()" />
