PrimeFaces 4.0 selectOneMenu-ajax-call適用於GlassFish 4.0，但不適用於Tomcat 7.0.27嗎？

Question

我已經使用GlassFish 4.0和PrimeFaces 4.0在本地計算機上開發了Java7 EE Web項目。 我已經通過運行Apache Tomcat 7.0.27的WebServer上的.war文件成功部署了它。
除以下代碼片段外，其他所有內容均相同：

...

<h:form id="autoComplete">
    <p:autoComplete id="auto" size="55" converter="autoConverter" value="#{autoComplete.indexObj}" var="per" itemLabel="#{per.name}"  itemValue="#{per.id}" completeMethod="#{autoComplete.complete}" onkeydown="styleOnKey();">
                <p:ajax event="itemSelect" listener="#{autoComplete.handleComplete}" update=":content" oncomplete="styleOnKey();"/>
    </p:autoComplete>
</h:form>

...

<h:form id="selectMenu">
    <p:selectOneMenu value="#{autoComplete.strSelectedSearch}">
        <c:forEach items="#{autoComplete.lstSearches}" var="search">
            <f:selectItem itemLabel="#{search}" itemValue="#{search}" />
        </c:forEach>
        <p:ajax event="change" update=":autoComplete:auto :content" listener="#{autoComplete.handleSelect(event)}"/>
    </p:selectOneMenu>
</h:form>

...

還有我的支持豆的一些片段：

@ManagedBean(name = "autoComplete")
@ViewScoped
public class AutoCompleteBean implements Serializable {

    ...
        public void handleComplete(SelectEvent event) {
            Logger.Log("complete fired");
        }

    ...

         public void handleSelect(SelectEvent event) {
            Logger.Log("select fired");
        }

    ...
}

有趣的是，在Windows 7 SP1上將.war文件與GlassFish 4.0一起使用時，p：selectOneMenu（handleSelect）上的ajax事件正在觸發。
如果要在使用Apache Tomcat 7.0.27的Windows 2008 R2服務器上部署此代碼，則不會。
有人知道為什么會這樣嗎？ 有人能夠重現嗎？
其余代碼的工作原理相同。
任何幫助將不勝感激... ^^

編輯：我設法在Tomcat日志中找到以下StackTrace：

我通過在中使用以下代碼片段解決了此問題：

...

<p:ajax event="change" update=":autoComplete:auto :content" onsuccess="#{autoComplete.handleSimulatedSelect(event)}"/>

...

在兩個服務器上都可以使用onSuccess-Attribute，但是有人對此有一個合理的解釋嗎？
