无法通过CRM 2011中的附加参数传递帐户类型

我已经编写了这个通用函数，基本上是克隆表单上的属性，并将它们传递给自己…

/*
Opens a new window, copying the current page, and loading the new item with the current values
* Sample call *
var url = "main.aspx?etn=task&pagetype=entityrecord";
var features = 'location=no,status=yes,scrollbars=no,menubar=no,toolbar=no,width=900,height=600';
CommonLib.openClone(url, '_blank', features, Xrm.Page.getAttribute(null));
*/
openClone: function (url, windowName, features, attributes) {
    var qsParams = "";
    var qs;
    for (var i = 0; i < attributes.length; i++) {
        qs = CommonLib.getExtraQS(attributes[i]);
        if (qs.length > 0) {
            qsParams += qs + "&";
        }
    } //end for
    // Remove extra &
    qsParams = qsParams.substring(0, qsParams.length - 1);
    window.open("/" + Xrm.Page.context.getOrgUniqueName() + "/" + url + "&extraqs=" + encodeURIComponent(qsParams), windowName, features, false);
},
/*
returns the extraqs value for the attribute, non-encodURIComponent-ed
*/
getExtraQS: function (attribute) {
    var extraQS = "";
    if (attribute != null && attribute.getValue() != null) {
        // Set name value based on type and id
        switch (attribute.getAttributeType()) {
            case "lookup":
                var value = attribute.getValue();
                var name = attribute.getName();
                if (value != null && value.length > 0) {
                    value = value[0];
                    extraQS = name + "=" + value.id + "&" + name + "name=" + value.name;
                    switch(value.typename){
                        case 'account':
                        case 'contact':
                        case 'systemuser':
                        case 'team':
                            extraQS += "&" + name + "type=" + value.typename;
                        break;
                    }
                }
                break;
            case "datetime":
                extraQS = attribute.getName() + "=" + CommonLib.getCRMDateFormat(attribute.getValue());
                break;
            default:
                extraQS = attribute.getName() + "=" + attribute.getValue();
                break;
        }
    }
    return extraQS;
}

一切工作正常，除非我试图传递类型为account的属性。我得到标准的"错误"。发生了错误。"如果我跳过第二个switch语句，那么我不会得到一个CRM Sever错误，而是一个试图反序列化对象的CRM javascript错误，因为它没有类型集，这会导致空指针错误。

有什么办法让它工作吗?

编辑:打开CRM服务器跟踪日志记录导致此异常，该异常将regardingobjecdtype列为无效参数，即使它正是SDK所说的使用(http://msdn.microsoft.com/en-us/library/gg334375.aspx)，如果我传递除该参数外的所有内容，我将在CRM javascript中获得javascript异常，因为typename为空。
