我在使用primefaces 5.0和jsf 2.2.5时遇到了问题。用一个
p:tabView
有两个标签共享同一个ManagedBean,同一个对象事件 tabChange
未按预期工作。当用户更改选项卡时,我想执行相同的验证,就像他单击了按钮一样,但事件没有刷新bean值,但是值正在发布。我能用这个简单的例子重现问题。
xhtml代码:
<h:body>
<div class="well">
<h:form id="testeForm">
<p:tabView id="tView">
<p:ajax event="tabChange"
process="@this"
update="@form"
listener="#{testeBean.onTabChange}" />
<p:tab id="tab1" title="tab1">
<p:inputText id="teste1"
value="#{testeBean.evento.nome}" />
<p:commandButton id="savetab1"
process="tab1"
update="@form"
actionListener="#{testeBean.saveTab1}"
value="salvarTab1">
</p:commandButton>
</p:tab>
<p:tab id="tab2" title="tab2">
<p:inputText id="teste2"
value="#{testeBean.evento.descricao}" />
<p:commandButton id="savetab2"
process="tab2"
update="@form"
actionListener="#{testeBean.saveTab2}"
value="salvarTab2">
</p:commandButton>
</p:tab>
</p:tabView>
</h:form>
</div>
</h:body>
ManagedBean:
package com.example.bean;
@ViewScoped
@ManagedBean(name = "testeBean")
@Getter
@Setter
public class TesteBean {
private Evento evento;
@PostConstruct
public void init() {
evento = new Evento();
}
public void saveTab1() {
System.out.println(evento);
}
public void saveTab2() {
System.out.println(evento);
}
public void onTabChange(TabChangeEvent evt) throws LoundScreenException {
System.out.println(evt.getTab().getId());
System.out.println(evento);
}
}
发布的价值:
我试了 process="@this" process="@form" process="@all" immediate="true"
但没有成功。我在这里错过了什么吗?
提前谢谢。
重要更新:
在花了一些时间调试primefaces代码后,在类 org.primefaces.component.api.UITabPanel
中我意识到Primefaces只处理其process()方法中的子组件,如果它不是ajax请求的来源:
if(isRequestSource(context)) {
return;
}
所以我删除了这段代码并重新编译了primefaces,现在它工作正常。我会打开这个问题,以防万一比我更有经验的人找到更好的解决方案。

素数6.0之后
<p:ajax event="*" listener="*" skipChildren="false">
skipChildren =“ false”
提供帮助,并在调用侦听器的函数之前将值设置为托管bean。
