我正在尝试根据我在 Internet 上找到的信息使用 ajax 事件实现一个简单的复合组件,但我总是收到错误 javax.el.PropertyNotFoundException

我已经寻找解决方案,但我无法弄清楚我做错了什么。

环境: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并且我只做一些增强。

这是代码的快照。

时间选择.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>

托管 bean 中的方法称为:

@ManagedBean(name = "pieChartBean")
@ViewScoped

..... 

public void timeValChange(AjaxBehaviorEvent  event){

    //code here

}

错误:(更新了完整的堆栈跟踪)
