Question

我在项目中使用Primefaces Ultima template。我遇到了试图在页面上触发动作监听器的问题。

我使用ultima template.xhtml作为我的应用程序的模板。

的template.xhtml

到目前为止，我已就此问题进行了一些研究，并且遇到了与@BalusC提出的answer类似的问题，但我无法找到问题。我需要你的帮助！

Answer 1

您正在将p：confirm与p：commandButton结合使用，但未定义全局p：confirmDialog。

您有两种选择：

从p：commandButton中删除p：confirm子项。
向您的页面添加全局p：confirmDialog（请参阅PrimeFaces-Showcase中的p：confirmDialog示例）。然后在按下确认对话框中的“是”按钮时调用actionListener。

行动listerner没有开火
