我正在开发我的第一个 jsf2 Richfaces 应用程序，现在我面临以下问题：

我有以下菜单

<rich:panelMenu >
            <rich:panelMenuGroup >
                 <rich:panelMenuItem label="Users" name="Users " />
                 <rich:panelMenuItem label="Orders" name="Orders"  />
            </rich:panelMenuGroup>

</rich:panelMenu>

我希望在单击 panelMenuItem 时创建一个新选项卡，并且在此新选项卡中必须插入一个包含我的应用程序的所有用户的表

我看到了一些这种类型的例子

 <rich:tabPanel switchType="client" id="tabPanel">
    <c:forEach items="#{handlerTab.tabsName}" var="tabName">
        <rich:tab name = ... >

    </rich:tab>
</c:foreach>

但不知道在我的新标签中插入表格

我能怎么做？

坦克供您回复，但我不想在视图中声明所有选项卡，我想动态添加和删除选项卡，现在我已经设法做到了

 <rich:panelMenu >
 <rich:panelMenuGroup >
     <rich:panelMenuItem label="Users" name="Users"  action="#{tabsBean.createTabs()}" render="tabs" />
     <rich:panelMenuItem label="Orders" name="Orders"  action="#{tabsBean.createTabs()}" render="tabs" />
 </rich:panelMenuGroup>                


<h:panelGrid id="tabs" binding="#{tabsBean.panelGrid}"/>

然后我有一个管理标签的bean

@ManagedBean
@SessionScoped
public class TabsBean {

   private HtmlPanelGrid panelGrid;
   private Integer numOfTabs;

   @PostConstruct
   public void init(){numOfTabs=1;}


   public Integer getNumOfTabs() {
    return numOfTabs;
   }

   public void setNumOfTabs(Integer numOfTabs) {
    this.numOfTabs = numOfTabs;
   }

   public TabsBean() {
   }

   public HtmlPanelGrid getPanelGrid() {
    return panelGrid;
   }

   public void setPanelGrid(HtmlPanelGrid panelGrid) {
    this.panelGrid = panelGrid;
   }

   public void createTabs (){       


    FacesContext context = FacesContext.getCurrentInstance();
    Application application = context.getApplication();
    UITabPanel tabPanel = (UITabPanel)application.createComponent(UITabPanel.COMPONENT_TYPE);
    tabPanel.setSwitchType(SwitchType.ajax);

    for (int i=0; i<numOfTabs; i++){
        UITab tab = new UITab();
        tab = (UITab)application.createComponent(UITab.COMPONENT_TYPE);
        tab.setName("User Count "+i);
        tabPanel.getChildren().add(tab);

    }
    numOfTabs++;
    panelGrid.getChildren().clear();
    panelGrid.getChildren().add(tabPanel);
   }


}

现在我的问题是我必须在此选项卡中添加组件（包含所有用户的数据表、用于插入用户的表单等）

我能怎么做？

如果您希望菜单打开具有特定内容的选项卡，最好预先创建选项卡并将其隐藏，并根据要求显示（渲染）。要创建，Users请执行以下操作：

创建一个User类（如果你没有）

public class User {     

    private String name;
    private String country;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getCountry() {
        return country;
    }

    public void setCountry(String country) {
        this.country = country;
    }
}

创建UserTab托管 bean

import java.io.Serializable;
import java.util.ArrayList;
import java.util.List;
import javax.faces.bean.ManagedBean;
import javax.faces.bean.ViewScoped;

@ManagedBean
@ViewScoped
public class UserTab implements Serializable {

    private List<User> users;
    private boolean rendered;

    public UserTab() {
        //Initialize list
        users = new ArrayList();

        //Initialize rendered attribute
        rendered = false;

        //Replace this for your User data retrieving method
        createDummyUsers();
    }

    private void createDummyUsers() {
        User user = new User();

        user.setName("John Doe");
        user.setCountry("USA");
        users.add(user);

        user = new User();
        user.setName("Bill Doe");
        user.setCountry("Canada");
        users.add(user);

        user = new User();
        user.setName("Winston Doe");
        user.setCountry("England");
        users.add(user);
    }

    public void showTab() {
        rendered = true;
    }

    public void hideTab() {
        rendered = false;
    }

    public List<User> getUsers() {
        return users;
    }

    public void setUsers(List<User> users) {
        this.users = users;
    }

    public boolean isRendered() {
        return rendered;
    }

    public void setRendered(boolean rendered) {
        this.rendered = rendered;
    }
}

创建一个选项卡处理程序：

import java.io.Serializable;
import javax.faces.bean.ManagedBean;
import javax.faces.bean.ViewScoped;

@ManagedBean
@ViewScoped
public class TabHandler implements Serializable {

    private String activeTab;

    public TabHandler() {
        activeTab = "none";
    }

    public String getActiveTab() {
        return activeTab;
    }

    public void setActiveTab(String activeTab) {
        this.activeTab = activeTab;
    }
}

创建视图

<h:body>
        <h:form>
            <rich:panelMenu >
                <rich:panelMenuGroup >
                    <rich:panelMenuItem label="Users" name="Users" 
                                        actionListener="#{userTab.showTab()}">
                        <f:ajax event="select"
                                execute="@this"
                                render="tabPanel"
                                listener="#{tabHandler.setActiveTab('usersTab')}"/>
                    </rich:panelMenuItem>
                    <rich:panelMenuItem label="Orders" name="Orders"  />
                </rich:panelMenuGroup>
            </rich:panelMenu>


            <rich:tabPanel id="tabPanel"
                           switchType="client"
                           activeItem="#{tabHandler.activeTab}">

                <rich:tab id="mainTab">


                </rich:tab>

                <rich:tab id="usersTab"
                          rendered="#{userTab.rendered}">
                    <f:facet name="header">
                        <h:outputLabel value="Users"/>
                        <h:commandLink value="  X" actionListener="#{userTab.hideTab()}"/>
                    </f:facet>
                    <rich:dataTable value="#{userTab.users}"
                                    var="user">

                        <rich:column>
                            #{user.name}
                        </rich:column>

                        <rich:column>
                            #{user.country}
                        </rich:column>
                    </rich:dataTable>

                </rich:tab>

            </rich:tabPanel>
        </h:form>
    </h:body>

执行相同的步骤并为类添加所需的标签Order。

c:forEach如果您想通过单击添加选项卡，则不是一个选项。您想要的是动态添加组件：
