获取javax.el.PropertyNotFoundException异常

Question

我正在使用复合组件来构建自动完成组件。.当我尝试引用completeMethod.am的方法来获取此异常时。

这是代码

在我的parent.xhtml中

<composite:attribute name="completefornameforreportee"
                     method-signature="java.util.List m(java.lang.String)"/>
<p:autoComplete id="empIdText2" value="#{cc.attrs.empNameforreportee}"
                completeMethod="#{cc.attrs.completefornameforreportee}">
    <p:ajax event="itemSelect"
            listener="#{cc.attrs.bean[cc.attrs.handlerforempNamereportee]}"
            update=":form" />
</p:autoComplete>

在complete.xhtml中

bean="#{autoCompleteBean}"
completefornameforreportee="#{autoCompleteBean.completeforNameforreportee}"

AutocompleteBean.java

public List<String> completeforNameforreportee(String query) throws Exception {
    System.out.println("called");
    List<String> finalNameResults = new ArrayList<String>();
    return finalNameResults;
}

堆栈跟踪：

Answer 1

#{autoCompleteBean.completeforNameforreportee}期望属性completeforNameforreportee具有扩展类型以及getter和setter。 像这样：

public <YourType> completeforNameforreportee;

public <YourType> getCompleteforNameforreportee() {
    return completeforNameforreportee;
}

public void setCompleteforNameforreportee(<YourType> completeforNameforreportee) {
    this.completeforNameforreportee = completeforNameforreportee;
}
