ColdFusion 11似乎呈现了超类和类的定义

在ColdFusion应用程序中，我有一个名为ProjectBeanService的类，它扩展了另一个名为AjaxBeanService的类。

在CF8中，代码似乎工作正常，在IE中调试应用程序时，我看到这个呈现的JavaScript：

<script type="text/javascript">
    var _cf_ProjectBeanService=ColdFusion.AjaxProxy.init('/components/ProjectBeanService.cfc','ProjectBeanService');
    _cf_ProjectBeanService.prototype.get=function(sPropertyName,sBeanType,nID,sSection,nRevision) { return ColdFusion.AjaxProxy.invoke(this, "get", {sPropertyName:sPropertyName,sBeanType:sBeanType,nID:nID,sSection:sSection,nRevision:nRevision});};
    _cf_ProjectBeanService.prototype.getAll=function(sBeanType,nID,sSection,nRevision) { return ColdFusion.AjaxProxy.invoke(this, "getAll", {sBeanType:sBeanType,nID:nID,sSection:sSection,nRevision:nRevision});};
    _cf_ProjectBeanService.prototype.set=function(sPropertyName,oPropertyValue,sBeanType,nID,sSection,nRevision) { return ColdFusion.AjaxProxy.invoke(this, "set", {sPropertyName:sPropertyName,oPropertyValue:oPropertyValue,sBeanType:sBeanType,nID:nID,sSection:sSection,nRevision:nRevision});};
</script>

但是，当我尝试在CF11下运行相同的应用程序时，会呈现类方法和超类方法：

<script type="text/javascript">/* <![CDATA[ */
    var _cf_ProjectBeanService=ColdFusion.AjaxProxy.init('/components/ProjectBeanService.cfc','ProjectBeanService');
    _cf_ProjectBeanService.prototype.get=function(sPropertyName,sBeanType,nID,sSection,nRevision) { return ColdFusion.AjaxProxy.invoke(this, "get","4789898A8974AC60", {sPropertyName:sPropertyName,sBeanType:sBeanType,nID:nID,sSection:sSection,nRevision:nRevision});};
    _cf_ProjectBeanService.prototype.getAll=function(sBeanType,nID,sSection,nRevision) { return ColdFusion.AjaxProxy.invoke(this, "getAll","4789898A8974AC60", {sBeanType:sBeanType,nID:nID,sSection:sSection,nRevision:nRevision});};
    _cf_ProjectBeanService.prototype.set=function(sPropertyName,oPropertyValue,sBeanType,nID,sSection,nRevision) { return ColdFusion.AjaxProxy.invoke(this, "set","4789898A8974AC60", {sPropertyName:sPropertyName,oPropertyValue:oPropertyValue,sBeanType:sBeanType,nID:nID,sSection:sSection,nRevision:nRevision});};
    _cf_ProjectBeanService.prototype.get=function(sBeanName,sPropertyName) { return ColdFusion.AjaxProxy.invoke(this, "get","4789898A8974AC60", {sBeanName:sBeanName,sPropertyName:sPropertyName});};
    _cf_ProjectBeanService.prototype.destroySessionBean=function(sBeanName) { return ColdFusion.AjaxProxy.invoke(this, "destroySessionBean","4789898A8974AC60", {sBeanName:sBeanName});};
    _cf_ProjectBeanService.prototype.createSessionBean=function(sBeanName,sBeanType,sDAOName) { return ColdFusion.AjaxProxy.invoke(this, "createSessionBean","4789898A8974AC60", {sBeanName:sBeanName,sBeanType:sBeanType,sDAOName:sDAOName});};
    _cf_ProjectBeanService.prototype.getAll=function(sBeanName) { return ColdFusion.AjaxProxy.invoke(this, "getAll","4789898A8974AC60", {sBeanName:sBeanName});};
    _cf_ProjectBeanService.prototype.getSessionBean=function(sBeanName) { return ColdFusion.AjaxProxy.invoke(this, "getSessionBean","4789898A8974AC60", {sBeanName:sBeanName});};
    _cf_ProjectBeanService.prototype.set=function(sBeanName,sPropertyName,oPropertyValue) { return ColdFusion.AjaxProxy.invoke(this, "set","4789898A8974AC60", {sBeanName:sBeanName,sPropertyName:sPropertyName,oPropertyValue:oPropertyValue});};
    _cf_ProjectBeanService.prototype.reInitSessionBean=function(sBeanName,argument1,argument2,argument3,argument4) { return ColdFusion.AjaxProxy.invoke(this, "reInitSessionBean","4789898A8974AC60", {sBeanName:sBeanName,argument1:argument1,argument2:argument2,argument3:argument3,argument4:argument4});};
/* ]]> */</script>

在这段代码中，注意＆＃34; set＆＃34;定义了函数，它再次定义（并根据超类定义）。在我看来，ColdFusion 11正在渲染这个超类，而CF 8则没有。

有什么建议吗？

更新：

这是应用程序的精简版本，其中我能够重现错误。

到目前为止，我提出的唯一答案是，这必须是CF11中的一个错误，所以我能够修复＆＃34;它通过将父类中的方法标记为具有访问权限＆＃34; public＆＃34;而不是＆＃34;远程＆＃34;。我还不知道这会带来什么意想不到的后果，但它似乎解决了我的问题。如果有人有更好的建议，请告诉我，我会给那个人答复。
