< UI：调试/>标签在Facelets中不起作用（JSF 2.0） [英] <ui:debug/> tag not working in Facelets (JSF 2.0)

问题描述

我正在使用JSF 2.0和Facelets做一个项目。

I am doing a project using JSF 2.0 and Facelets.

我已经阅读了< ui：debug /> <的文档/ code>标签在按CTRL-SHIFT-D时提供有价值的故障排除信息。但这对我不起作用。请有人告诉我我错过了什么。

I have read documentations that the <ui:debug/> tag gives valuable troubleshooting information upon pressing CTRL-SHIFT-D. But this never works for me. Please anyone tell me what am I missing.

（我试过各种热键，但仍未成功。例如：< ui：debug hotkey = a/> ）

(I tried with various hotkeys, still no success. eg: <ui:debug hotkey="a"/>)

推荐答案

确保选择未保留的密钥通过webbrowser本身。对于Firefox，一个不错的选择是 x 。

Ensure that you pick a key which isn't reserved by the webbrowser itself. In case of Firefox, a good choice is x.

<ui:debug hotkey="x" />

与此问题无关，我建议添加呈现属性以确保它不会在生产环境中弹出。例如

Unrelated to the problem, I recommend to add a rendered attribute to ensure that it won't pop in a production environment. E.g.

<ui:debug hotkey="x" rendered="#{facesContext.application.projectStage == 'Development'}" />

与此相结合 web.xml

<context-param>
    <param-name>javax.faces.PROJECT_STAGE</param-name>
    <param-value>Development</param-value>
</context-param>
