对于我的 Web 应用程序，我使用 RichFaces 4.X 版本的 ModalPanel 作为弹出窗口。该应用程序在 JSF2.0 中并在 Apache Tomcat 7 上运行。现在，我的弹出窗口工作正常，但是当我关闭弹出窗口时，我的父窗口没有刷新。我可以看到父页面正在加载（因为我可以看到绑定变量的所有 getter 方法都被调用），但我得到的只是一个空白页面。我的支持 bean 的范围是“会话”。我在这里粘贴我的 JSF 文件。

请让我知道我错过了什么。我已经尝试了一整天，但现在什么都没有出现在我的脑海中。:(

        </h:panelGrid>
    </a4j:form>
</rich:modalPanel>
</f:view>
</body>
</html>

此外，在 ModalPanel commandButton oncomplete 方法中，我尝试了返回 true 和 false。

谢谢，简

您的父页面似乎根本没有刷新。那是因为您需要在要刷新的父页面上重新渲染组件：

<a4j:commandButton image="/default/Add1.png" 
       reRender="someComponentId(s) on the parent page" 
            oncomplete="Richfaces.hideModalPanel('selectMaterial');">
