当我在xhtml页面中使用下一个代码时
<p:repeat value="#{mybeanView.usernames}" var="username" >
<h:outputText value="#{username}" />
</p:repeat>
它记录下一条消息（ INFO 和 WARNING ）
谁能解释为什么？
以及如何删除（或解决）这些警告？
[WARNING ]

我想你应该使用
<c:foreach>JSTL
<c:forEach>是视图构建时标记（<ui:repeat>是视图渲染时间标记） .另见：ui:repeat JSF 2.0 cannot render iterate p:row primefaces
