p:commandButton / p:commandLink 内的操作 / ActionListener 未触发

Question

我读过这篇文章： commandButton/commandLink/ajax action/listener方法未调用或输入值未更新

，但我仍然无法理解为什么我的问题没有解决。 恐怕我对英文解释的理解不完全正确。所以我将在这里放置我的代码片段。

仅供参考，我对英语的理解程度仍然中等。我的英语能力一般般。

我正在使用 Primefaces 3.0.RC1、EL 库 2.2、JSF 2.1、JSTL 1.1、GlassFish 3.x，使用 Netbeans 7.0.1 编码，

现在我们来了代码：

t​​emplate.xhtml

<h:head>
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
    <h:outputStylesheet name="default.css" library="css"/>
    <h:outputStylesheet name="cssLayout.css" library="css"/>
    <h:outputStylesheet name="style.css" library="css"/>
    <title>MFI Core Banking System</title>
</h:head>

<h:body>
    <f:view>
        <div id="top">
            <ui:include src="header.xhtml"/>
        </div>

        <div id="menuBar">
            <ui:include src="menubar.xhtml"/>
        </div>

        <div id="content" class="center_content">
            <ui:insert name="content">Content</ui:insert>
        </div>

        <div id="bottom">
            <ui:include src="footer.xhtml"/>
        </div>
    </f:view>


</h:body>

header.xhtml 和 footer.xhtml 只有 UI:Composition 声明和

和 标记仅有的。

menubar.xhtml 如下：

<ui:composition xmlns="http://www.w3.org/1999/xhtml"
            xmlns:ui="http://java.sun.com/jsf/facelets"
            xmlns:h="http://java.sun.com/jsf/html"
            xmlns:f="http://java.sun.com/jsf/core"
            xmlns:p="http://primefaces.org/ui">
<f:view>
    <h:form>
        <p:menubar >
            <p:menuitem value="Home" action="/index.xhtml?faces-redirect=true" icon="ui-icon ui-icon-home"/>
            <p:submenu label="CIF" icon="ui-icon ui-icon-bookmark">
                <p:menuitem value="Manajemen CIF" action="/modul/cif/cifManagement?faces-redirect=true"/>
                <p:submenu label="CIF Grouping ">
                    <p:menuitem value="Search" action="/modul/cif/SearchGroupNew.xhtml?faces-redirect=true"/>
                    <p:menuitem value="Create" action="/modul/cif/CreateGroupNew.xhtml?faces-redirect=true"/>
                </p:submenu>
                <p:menuitem value="Analyze" url="#"/>
                <p:menuitem value="Directorate " action="/modul/userManagement/Struktural.Directorate.xhtml?faces-redirect=true"/>
            </p:submenu>
        </p:menubar>
    </h:form>
</f:view>
</ui:composition>

这是我的示例页面（Directorate）：

<ui:composition xmlns:ui="http://java.sun.com/jsf/facelets"

这是托管 bean：

@ManagedBean(name = "directorateBean")
@ViewScoped
public class structuralDirectorateManagedBean implements Serializable {

private DirectorateDAO directorateService;
/* Initialize variable */
private List<Directorate> directorateList;
private Directorate directorate = new Directorate();
private Directorate selectedDirectorate = new Directorate();
private static final String Creator;
private boolean fieldsetCollapse = true;
private boolean DirectorateStatus = false;

/* init */
@PostConstruct
public void init() throws SQLException {
    if (directorateService == null) {
        directorateService = FactoryDAO.getDirectorateDAO();
    }
    directorateList = directorateService.findAll();
    directorate.setDirectoratestatus(DirectorateStatus);
    directorate.setCreator(Creator);
}

/* Basic Method */
public void add() throws SQLException {
    System.out.println("Directorate Code : " + directorate.getDirectoratecode());
    directorateService.create(directorate); // insert record to datatabse
    directorateList.add(directorate); // insert object to List<Object>
    directorate = new Directorate(); // Reset Form
    directorate.setDirectoratestatus(DirectorateStatus); // set default
    directorate.setCreator(Creator); // set default
}

public  void test(){
    System.out.println("TEST!!");
}

public void edit(Directorate directorate) {
    System.out.println("Directorate code to edit : " + directorate.getDirectoratecode());
    this.selectedDirectorate = directorate;
}

public void delete(Directorate directorate) throws SQLException {
    directorateService.remove(directorate); // delete record within Database
    directorateList.remove(directorate); // delete record within List
}

public void update(ActionEvent event) throws SQLException {
    directorateService.edit(selectedDirectorate); // update record to database
    selectedDirectorate = new Directorate(); // reset form
}

/** Getter Setter */
public List<Directorate> getDirectorateList() throws SQLException {

    return directorateList;
}

public Directorate getDirectorate() {
    return directorate;
}

public boolean isFieldsetCollapse() {
    return fieldsetCollapse;
}

public void setFieldsetCollapse(boolean fieldsetCollapse) {
    this.fieldsetCollapse = fieldsetCollapse;
}

public Directorate getSelectedDirectorate() {
    return selectedDirectorate;
}

public void setSelectedDirectorate(Directorate selectedDirectorate) {
    this.selectedDirectorate = selectedDirectorate;
}

}

一切运行顺利，显示数据库中的记录，p:selectOneMenu 运行良好。

这个按钮也运行得很好：

<p:commandButton id="btnSubmitDirectorate" value="Submit" update="@form" action="#{directorateBean.add()}"/>

但是，这个按钮和 commandLink 不起作用，Action 和 ActionListener 都没有被触发：

<p:commandButton icon="ui-icon ui-icon-pencil" title="Edit #{dir.directoratename}" action="#{directorateBean.edit(dir)}" update="panelDetail" oncomplete="updateDlg.show();"/>

<p:commandLink value="#{dir.directoratecode}" actionListener="#{directorateBean.test}"/>

如果我问得太多，我很抱歉，也许我在这里很愚蠢..XD

，但我只是无法克服它并开始感到沮丧..

感谢您的回复..:) 祝你今天过得愉快..

Answer 1

“Directorate”视图中有一个很大的 ，其中包含许多不同的部分。当您在其中一个部分中调用操作时，所有其他部分的数据也将被提交（并验证！）。乍一看，您似乎没有注意到那些“需要值”验证消息，因为默认情况下这些部分是折叠/隐藏的。

您需要删除“上帝” 并为字段集、数据表和两个对话框提供各自的。因此，您应该有 4 个单独的表格，每个表格都有自己的责任。然而，它们可以毫无问题地绑定到同一个 bean。

顺便说一下， 不属于包含文件，也不属于模板客户端。主模板中应该只有一个。
