Richfaces 4.5.17 Menuitem操作方法不起作用

我正在將Web應用程序從JEE5遷移到JEE7。我的問題涉及表示層。

所有系統頁面都從RichFaces 3.3.3遷移到4.5.17。我一直遵循正式的遷移指南（[https://developer.jboss.org/wiki/RichFacesMigrationGuide33x-4xMigration][1]），Richfaces論壇（https://developer.jboss.org/en/richfaces），當然還有StackOverflow。但是沒有人爲我提供瞭解決我的問題的方法：

應用程序菜單是在managedbean上構建的（不包含xhtml上的標記）。它在RF 3.3.3上運行良好，使用類HtmlToolBar，HtmlDropDownMenu，HtmlMenuGroup和HtmlMenuItem。但是，在遷移到RF4相應的類後，MenuItem操作方法不再被觸發。 用戶單擊MenuItem後，頁面刷新並向當前頁面本身發出請求，而不是所需的頁面。

遷移的代碼如下所示：

如果你有@action問題，你應該顯示它（並說出它應該做什麼），HTML部分在很大程度上是不相關的。 – Makhiel

馬凱爾！謝謝回覆！因爲它沒有被解僱，所以這個動作沒有關係。xhtml可能是相關的，因爲當RF4存在一些問題時，例如標籤未被放置（這導致RF4不加載JavaScript）。這就是我發佈xhtml文件的原因。另外，我剛剛發佈了web.xml和faces-config。謝謝！ – Bill

啊，看起來你有嵌套形式，擺脫他們。如果這沒有幫助嘗試手動創建菜單，並看看是否有效。 – Makhiel

解決了！

1）改性的init（）上ManagedBean：

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

2.）上montarToolbar（）方法增加了menuItem.setMode(Mode.ajax);

3）修改了XHTML頁面：

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

這就是它！
