p：remoteCommand无效后重定向

我遇到了在执行某些操作后将用户重定向到主页的问题。我搜索了stackoverflow并找到了很多解决方案，特别是来自@BalusC，但它们都没有为我工作。

pageA - remoteCommand：

<p:remoteCommand name="submit" process="@this" action="#{beanA.submitForm}"/>

pageA - 提交按钮，调用用于签名内容的模式对话框

<p:commandButton value="Sign data" id="sign" actionListener="#{beanA.signData}" global="false" styleClass="button" />

用户单击commandButton后，有一些数据逻辑正在bean中运行，模态对话框用自己的bean调用，从那里调用p：remoteCommand：

RequestContext.getCurrentInstance().execute("submit()");    

String message = "Redirect successfuly done!";

FacesContext context = FacesContext.getCurrentInstance();
FacesMessage facesMessage = new FacesMessage(FacesMessage.SEVERITY_INFO, "INFO:" , message);

context.addMessage("form:h_m", facesMessage); // h:message on landing page waiting for message  

externalContext.getFlash().setKeepMessages(true);

return "/view.xhtml?faces-redirect=true&includeViewParams=true";

h：view.xhtml中的消息：

<h:form id="form">  
 <div id="divs">
  <div id="top">
   <h:message id="h_m"/>    
    .....
    .....
  </div>
 </div>
</h:form>

长话短说 - 当用户按下提交按钮（调用对话框）时，弹出模式对话框，用户再次单击提交按钮，有一些逻辑需要处理，然后调用remoteCommand并关闭弹出窗口。这是重定向应该完成的时刻，但弹出窗口关闭后没有任何反应，只是错误：

没有动作，我不确定为什么URL为空？

2 个答案:

答案 0 :(得分：2)

这是Liferay Faces Bridge在3.2.5-ga6（以及最有可能的早期版本）中执行ajax重定向的方式中的错误。我为此开了一张票（FACES-2485）。如果可能，我建议您使用非ajax重定向来解决此问题。只需将ajax="false"添加到调用重定向的command组件中：

<p:commandButton action="#{bean.methodWithRedirect}" ajax="false" />

答案 1 :(得分：0)

我不确定<p:remoteCommand>是否支持将网址作为操作的返回值。

但您可以像以下所示以编程方式重定向：
