Richfaces 4.5.17 Menuitem操作方法不起作用

开发者!!

我正在将Web应用程序从JEE5迁移到JEE7。我的问题涉及表示层。

所有系统页面都从RichFaces 3.3.3迁移到4.5.17。我一直关注官方迁移指南（[https://developer.jboss.org/wiki/RichFacesMigrationGuide33x-4xMigration][1]），Richfaces论坛（https://developer.jboss.org/en/richfaces），当然还有StackOverflow。但没有人能为我解决我的问题：

应用程序菜单是在managedbean上构建的（不是xhtml上的标签）。它在RF 3.3.3上运行良好，使用类HtmlToolBar，HtmlDropDownMenu，HtmlMenuGroup和HtmlMenuItem。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，页面会刷新并请求当前页面本身，而不是所需的页面。

迁移的代码如下：

ManagedBean 

package br.gov.serpro.sfitweb.ui.managedbean;

public class MenuMBTrecho implements Serializable {
    private static final long serialVersionUID = 1L;

    private UIToolbar toolbar;

    public MenuMBTrecho() {
    }

    @PostConstruct
    public void init() {
        montarToolbar();
    }

    public void montarToolbar() {
        FacesContext ctx = FacesContext.getCurrentInstance();

        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;
    }

}

请不要错过任何帮助我至少指出这个问题的原因。

解决了！

1。）修改了ManagedBean上的init（）：

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

2.。）在montarToolbar（）方法上添加了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>

那就是它!!
