selectonemenu没有出现

Question

I'm trying to make primefaces elements appear on my pages by taking code from the showcase, the menu worked well after some modifications but the selectonemenu refuses to appear. 我试图通过从展示柜中获取代码来使素数元素出现在我的页面上，经过一些修改后，菜单运行良好，但是selectonemenu拒绝出现。
it's not showing anything in the layout unit. 它在布局单元中未显示任何内容。 This is my xhtml code : 这是我的xhtml代码：

Answer 1

Your code works. 您的代码有效。 Which version of primefaces are you using? 您正在使用哪个版本的primeface？ Which app server are you deploying to? 您要部署到哪个应用服务器？ Which browser have you tested in? 您在哪个浏览器中进行过测试？ Is there anything else on the page besides the selectonemenu? 除了selectone菜单，页面上还有其他内容吗？

Try the following. 尝试以下方法。 Work with Primefaces 4 on Glassfish 3. 在Glassfish 3上使用Primefaces 4。
