我正在尝试使用基于我在Internet上找到的信息的ajax事件实现一个简单的复合组件，但我总是得到 错误javax.el.PropertyNotFoundException
我已经找到了解决方案，我无法弄清楚我做错了什么。
Enviroment：Jboss eap 5.1，Mojarra 2.1.6，primefaces 3.4.2 我无法切换到更高版本的jboss，因为我正在处理现有的应用程序而且我只做了一些改进。
以下是代码的快照。
timeselect.xhtml：
<composite:implementation>
<h:outputLabel for="ddTime" value="Time:" style="font-weight:bold"/>
<p:selectOneMenu id="ddTime" value="cc.attrs.value" style="width:125px" immediate="false">
<f:selectItem itemLabel="Select One" itemValue="" />
<f:selectItem itemLabel="Label1" itemValue="ID1" />
<f:selectItem itemLabel="Label2" itemValue="ID2" />
<f:selectItem itemLabel="Label3" itemValue="ID3" />
<p:ajax event="change" listener="#{cc.timelistener}" process="@this" required="true"/>
</p:selectOneMenu>
</composite:implementation>
组件Bean：
@FacesComponent("timeselect")
public class TimeSelectCC extends UINamingContainer {
public TimeSelectCC() {
// TODO Auto-generated constructor stub
}
@Override
public String getFamily() {
return "javax.faces.NamingContainer";
}
public void timelistener(AjaxBehaviorEvent event) {
FacesContext context = FacesContext.getCurrentInstance();
MethodExpression ajaxEventListener = (MethodExpression) getAttributes().get("timelistener");
if(ajaxEventListener != null){
ajaxEventListener.invoke(context.getELContext(), new Object[] { event });
}
}
}
从xhtml页面调用：
<myc:timeselect value="#{pieChartBean.selectedTime}" timelistener="#{pieChartBean.timeValChange}" />
//here - one more label & one more select
</h:panelGrid>
</ui:define>
Managed bean中的方法叫做：
@ManagedBean(name = "pieChartBean")
@ViewScoped
.....
public void timeValChange(AjaxBehaviorEvent event){
//code here
}
错误:(使用完整堆栈跟踪更新）
