PrimeFaces CommandButton Action未在Composite内部调用

Fer*_*afé 8 primefaces composite-component jsf-2

在下面的代码中,jsf html commandButton动作被完美地调用.但是没有调用primefaces commandButton动作.

如果放置相同的代码在复合(普通的xhtml页面)之外,两者都可以正常工作:

有什么建议？

今天我用PrimeFaces 5.1遇到了同样的问题.在我的情况下,我没有嵌套的表单,我已经process在p:commandButton我想要处理的表单元素上设置属性.然而,这还没有奏效.

"解决方案"是添加@this到要处理的组件列表中,如下所示:

<p:commandButton process="myFormField1 myFormField2 @this">

没有@this(通常不需要,因为按钮本身不需要处理/验证)我发现没有办法让任何这些在复合内部工作:

<p:commandButton action="#{bean.myAction}"...>
<p:commandButton type="button"> 嵌套 <p:ajax event="click" action="#{bean.myAction}"...>
<p:commandButton type="button" onclick="myAction()"> 与相关联 <p:remoteCommand name="myAction" action="#{bean.myAction}">

通过调试应用程序,我看到验证和更新模型阶段已正确执行,但随后在调用应用程序阶段没有排队事件,因此未执行任何操作.实际上,我可以在没有任何PrimeFaces或JSF抱怨的情况下指定我喜欢的内容action和actionListener属性值<p:commandButton>.

相反,它们可以按预期工作,但是您没有部分处理,因此它们可能不是一个可行的解决方案:

<p:commandButton action="#{bean.myAction}" ajax="false"...>
<p:commandButton type="button"...> 嵌套 <f:ajax event="click" action="#{bean.myAction}"...>

它必须是PrimeFaces的bug.

当你使用复合组件时,它是否已经放在ah:form标签中？嵌套表单时,不会触发命令按钮操作.

另一个问题可能是您正在尝试的ajax部件.Primefaces按钮具有update属性,但标准JSF没有.它将始终完成页面的完整刷新(嵌入时除外或在其中使用f:ajax标记)
