我的jsf bean中有一个复杂的方法:

I have a sophisticated method in my jsf bean :

public void saySomething() {
   log.debug("SAY SOMETHING !");
}

在jsf中有一个简单的按钮:

And a simple button in the jsf :

<p:commandButton
   value="say something"
   process="@this" update="@none" action="#{timetableBean.saySomething}" />

单击按钮，将导致我的简单日志记录:

Clicking on the button, results in my simple logging :

DEBUG PhaseTracker - BEFORE PHASE INVOKE_APPLICATION 5
DEBUG TimetableBean - SAY SOMETHING !
DEBUG PhaseTracker - AFTER PHASE INVOKE_APPLICATION 5

让我们转到下一个简单的案例. 将相同的按钮放在p:dataList里面时，像这样:

Let's go to next simple case. When placing that identical button inside a p:dataList like this :

<p:dataList id="groupUsers2" value="#{timetableBean.group.users}" var="user" itemType="circle" style="padding:0; margin: 0;">
   <p:commandButton
      value="#{user.data['selected'] ? 'V' : 'X'}"
      process="@this" update="@none" action="#{timetableBean.saySomething}" />
   <p:commandLink value="#{user.userId} - #{user.name}" process="@this" />
</p:dataList>

单击按钮，将导致我的简单日志记录:

Clicking on the button, results in my simple logging :

DEBUG PhaseTracker - BEFORE PHASE INVOKE_APPLICATION 5
DEBUG PhaseTracker - AFTER PHASE INVOKE_APPLICATION 5

saySomething()的方法未调用！

The method of saySomething() was not called !

我做错了什么?

推荐答案

问题已解决.

在此处

为了调用侦听器，应将p:dataList内部的组件封装为p:column

In order for listener to be invoked, the components inside the p:dataList should be encapsulated with p:column

<p:dataList id="groupUsers2" value="#{timetableBean.group.users}" var="user" itemType="circle" style="padding:0; margin: 0;">
  <p:column>
   <p:commandButton
      value="#{user.data['selected'] ? 'V' : 'X'}"
      process="@this" update="@none" action="#{timetableBean.saySomething}" />
   <p:commandLink value="#{user.userId} - #{user.name}" process="@this" />
  </p:column>
</p:dataList>

但是很奇怪，我没有在文档中看到它，因为它没有指定p:column.也许是在Primefaces 2.2.1 doc的勘误表中?

Strange though, i didnt see this in the documentation, as it doesnt specify the p:column. Perhaps it's in the errata for primefaces 2.2.1 doc ?
