Primefaces p:commandButton，未调用操作 [英] Primefaces p:commandButton with action not called

问题描述

Primefaces 3.2和JSF 2.1遇到了一些麻烦.

I've got some some troubles with Primefaces 3.2 and JSF 2.1.

我的代码是这样的:

<p:toolbar id="jeditortoolbar" styleClass="jeditortoolbar">
      <p:toolbarGroup align="left" height="25" style="height:25px">
        <p:commandButton type="button" title="#{msg.beenden}"/>
        <p:commandButton type="button" title="#{msg.neu}"/>
      </p:toolbarGroup>
</p:toolbar>

当我查看Primefaces Showcase时，我的p:commandButton需要

When I take a look at Primefaces Showcase my p:commandButton need

actionListener="#{myBean.myActionMethod}"

我的Bean需要像这样的方法

and my Bean need a Method like

public void myActionMethod(){}

我的p:toolbar标签周围有一个h:form！

我的Bean是ViewScoped.

My Bean is ViewScoped.

我的解决方法是 在*.xhtml文件

My Workaround is In *.xhtml File

<p:commandButton type="button" title="#{msg.neu}" onclick="addNewEmptyFile()"/>
<p:remoteCommand name="addNewEmptyFile" update=":codeTabForm">
   <f:setPropertyActionListener value="#{true}" target="#{myBean.myEvent}"/>
</p:remoteCommand>

在MyBean.java

In MyBean.java

private String myEvent;

public void setMyEvent(String value){ myActionMethod();}

这对我有用，但是我认为这是非常肮脏的代码.

This works for me but I think this is very dirty code.

每个人都可以帮我吗?

推荐答案

尝试一下

Bean.java

@ManagedBean
@ViewScoped
public class Bean {

    public String testButtonAction() {
        System.out.println("testButtonAction invoked");
        return "anotherPage.xhtml";
    }

    public void testButtonActionListener(ActionEvent event) {
        System.out.println("testButtonActionListener invoked");
    }

}

page.xhtml

page.xhtml

<p:toolbar>
  <p:toolbarGroup>
    <p:commandButton action="#{bean.testButtonAction}"/>
    <p:commandButton actionListener="#{bean.testButtonActionListener}"/>
  </p:toolbarGroup>
</p:toolbar>
