开发者！！

我正在将一个 Web 应用程序从 JEE5 迁移到 JEE7。我的问题与表示层有关。

所有系统页面都从 RichFaces 3.3.3 迁移到 4.5.17。我一直在关注官方迁移指南 ([https://developer.jboss.org/wiki/RichFacesMigrationGuide33x-4xMigration][1])、Richfaces 论坛 (https://developer.jboss.org/en/richfaces)，当然还有 StackOverflow。但没有人为我的问题提供解决方案：

应用程序菜单动态构建在 managedbean 上（不是 xhtml 上的标签）。它在 RF 3.3.3 上运行良好，使用 HtmlToolBar、HtmlDropDownMenu、HtmlMenuGroup 和 HtmlMenuItem 类。但是，在迁移到 RF4 对应的类之后，不再触发 MenuItem 操作方法。 用户点击 MenuItem 后，页面刷新并请求当前页面本身，而不是所需的页面。

迁移后的代码如下：

ManagedBean

        this.toolbar = (UIToolbar) ctx.getApplication().createComponent(ctx, UIToolbar.COMPONENT_TYPE,
                "org.richfaces.ToolbarGroupRenderer");

        // log.debug("User" + secCtx.getUserPrincipal().getCpf());

        UIDropDownMenu menuPlanejamento = new UIDropDownMenu();
        menuPlanejamento.setLabel("Planejamento");
        boolean mostraMenu = false;

        ///////// Submenu PPA /////////
        boolean mostraSubMenuPPA = false;
        UIMenuGroup subMenuPPA = new UIMenuGroup();
        subMenuPPA.setLabel("PPA");

        UIMenuItem menuItem = new UIMenuItem();
        menuItem.setMode(Mode.ajax);
        menuItem.setLabel("Cadastrar período de PPA");
        ExpressionFactory factory = FacesContext.getCurrentInstance().getApplication().getExpressionFactory();
        ELContext ELCtx = FacesContext.getCurrentInstance().getELContext();
        menuItem.setActionExpression(
                factory.createMethodExpression(ELCtx, "#{ppaMB.listarPpas}", String.class, new Class[] {}));

        subMenuPPA.getChildren().add(menuItem);
    }

    public UIToolbar getToolbar() {
        return toolbar;
    }

    public void setToolbar(UIToolbar toolbar) {
        this.toolbar = toolbar;
    }

请，任何至少指出我这个问题的原因的帮助将不胜感激。

【问题讨论】：

如果您对@action 有疑问，您应该展示它（并说明它应该做什么），HTML 部分在很大程度上是无关紧要的。
你好，马基尔！谢谢回复！动作做什么并不重要，因为它没有被触发。 xhtml 可能是相关的，因为 RF4 存在一些问题，例如，未放置标签（这导致 RF4 不加载 javascript）。这就是我发布 xhtml 文件的原因。另外，我刚刚发布了 web.xml 和 faces-config。谢谢！
啊，看起来你有嵌套的表单，去掉它们。如果这没有帮助，请尝试手动创建菜单，看看是否可行。

【解决方案1】：

解决了！

1.) 在 ManagedBean 上修改 init()：

@PostConstruct
    public void init(){
        menuPlanejamento = (UIDropDownMenu)FacesContext.getCurrentInstance().getApplication().createComponent(UIDropDownMenu.COMPONENT_TYPE);
}

2.) 在 montarToolbar() 方法中添加了menuItem.setMode(Mode.ajax)；

3.) 修改了xhtml页面：

<div id="menu">
        <h:form id="menuForm">
            <rich:toolbar id="menuToolbar">
                <rich:dropDownMenu id="menuPlanejamento" binding="#{menuMB.menuPlanejamento}"/> 
            </rich:toolbar>
        </h:form>
    </div>

就是这样！！
