我正在使用复合组件来构建自动完成组件..当我尝试为 completeMethod.am 引用方法时遇到此异常。

这是代码

在我的 parent.xhtml

<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>

在完整的.xhtml

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：

#{autoCompleteBean.completeforNameforreportee}期望一个completeforNameforreportee具有扩展类型和 getter 和 setter 的属性。像这样的东西：

public <YourType> completeforNameforreportee;

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

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