在 JBoss 上从 p:commandButton 更新 h:form 时出错 7.1.x
Error updating h:form from p:commandButton on JBoss 7.1.x
以下 .xhtml 不适用于 JBoss 7.1.0/7.1.1 和 PrimeFaces 5.3。不过，它确实适用于 WildFly，但我需要项目在两个平台上 运行：

Wildfly 默认使用 JSF2.2 实现，而 JBoss 7.1(.1) 使用 JSF 2.1 实现。您的代码通过使用相应的 xmlns:h="http://xmlns.jcp.org/jsf/html" 名称空间声明来假定 JSF 2.2 实现。我的建议是纠正这一点。
在一个已经删除的答案中，@BalusC 解释了实际发生的情况。对于 facelets 页面，xml 明智地没有错误。您有一个 h:form 和相应的命名空间声明。然而，h:form 不会被 jsf 2.1 实现解释为 jsf 标记，因为它没有正确的命名空间并且实际上是纯文本。您可以通过从 <p:commandButton> 中删除 update="@form" 并在浏览器中查看生成的源来检查这一点。您会在那里看到 <h:form...>。堆栈跟踪也没有显示 h:form 存在的任何迹象（也由@BalusC 提供），因此由于没有创建 jsf 表单组件，你 运行 进入你得到的错误。
以下 .xhtml 不适用于 JBoss 7.1.0/7.1.1 和 PrimeFaces 5.3。不过，它确实适用于 WildFly，但我需要项目在两个平台上 运行：

Wildfly 默认使用 JSF2.2 实现，而 JBoss 7.1(.1) 使用 JSF 2.1 实现。您的代码通过使用相应的 xmlns:h="http://xmlns.jcp.org/jsf/html" 名称空间声明来假定 JSF 2.2 实现。我的建议是纠正这一点。
在一个已经删除的答案中，@BalusC 解释了实际发生的情况。对于 facelets 页面，xml 明智地没有错误。您有一个 h:form 和相应的命名空间声明。然而，h:form 不会被 jsf 2.1 实现解释为 jsf 标记，因为它没有正确的命名空间并且实际上是纯文本。您可以通过从 <p:commandButton> 中删除 update="@form" 并在浏览器中查看生成的源来检查这一点。您会在那里看到 <h:form...>。堆栈跟踪也没有显示 h:form 存在的任何迹象（也由@BalusC 提供），因此由于没有创建 jsf 表单组件，你 运行 进入你得到的错误。
