獲取javax.el.PropertyNotFoundException異常

我使用複合組件來構建自動完成組件..當我嘗試引用completeMethod.am的方法獲取此異常。獲取javax.el.PropertyNotFoundException異常

下面是代碼

在我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complete.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; 
}

堆棧跟蹤：

向我們展示您的支持bean以及相關堆棧跟蹤，以獲得更好的幫助。 – Magnilex 2013-03-13 07:47:07

嗨，感謝您的快速回復。我添加了這些 – Karthik 2013-03-13 07:53:01

我不知道標記。你能指點我們的文件嗎？ – 2013-03-13 08:05:31

#{autoCompleteBean.completeforNameforreportee}預計屬性completeforNameforreportee具有預期類型和getter和setter。例如：

public <YourType> completeforNameforreportee; 

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

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

但是autocomplete中的completemethod會自動觸發一個帶有String參數的方法。怎麼可能？ – Karthik 2013-03-13 08:02:22

然後你有一個getter和setter的String屬性。 – Magnilex 2013-03-13 08:07:14

我認爲你喜歡Magnus，但請參閱[方法表達式]（http://docs.oracle.com/javaee/5/tutorial/doc/bnahq.html#bnahz）。 – 2013-03-13 08:19:14
