p：commandButton或p：带有actionListener和结果的按钮？ [英] p:commandButton or p:button with actionListener and outcome?

问题描述

我正在使用PrimeFaces并有一个Save按钮，基本上是一个maintenanceTask被发送到我的页面，我在这里编辑它，然后按Save，它应该保存到数据库然后重定向到原始页面。我有一个工作的Save方法，但似乎无法同时启动导航和方法。

I'm using PrimeFaces and have a Save button, basically a maintenanceTask is sent to my page, I edit it within here, then press Save and it should be saved to the database and then redirected to the original page. I have a working Save method, but can't seem to get both the navigation and method to fire off.

    <p:commandButton value="#{message.commonButtonSave}"
        title="#{message.commonSaveTooltip}"
        rendered="#{maintenanceTaskEnquiryBean.screenMode == 'editTasks'}"          
        disabled="#{maintenanceTaskEnquiryBean.outstandingEditCount != 0}"
        action="/definemaintenance/MaintenanceTasksActivity"
        actionListener="#{maintenanceTaskEnquiryBean.save}" >           
    </p:commandButton>  

我现在有什么，但我尝试了很多不同的变化，包括p：按钮和p：commandButton，listener / actionListener，target / outcome / action等...

There is what I have at the minute, but I have tried many different variations on this including p:button and p:commandButton, listener/actionListener, target/outcome/action etc...

有任何建议吗？

谢谢。

推荐答案

如果您想要执行操作并在之后导航，请使用操作属性并返回导航规则。

If you want to perform action, and navigate afterwards, use action attribute and return the navigation rule as a result.

<p:commandButton value="#{message.commonButtonSave}"
    title="#{message.commonSaveTooltip}"
    rendered="#{maintenanceTaskEnquiryBean.screenMode == 'editTasks'}"          
    disabled="#{maintenanceTaskEnquiryBean.outstandingEditCount != 0}"
    action="#{maintenanceTaskEnquiryBean.save}">           
</p:commandButton>  

save（）方法看起来像什么像这样

The save() method would look something like this

public String save() {
    // perform whatever you need to, and then
    return "<some navigataion rule>";
}

返回字符串应该打开所需的页面 / definemaintenance / MaintenanceTasksActivity 。

The return string should open the desired page /definemaintenance/MaintenanceTasksActivity.
