Netsuite获取自定义字段Java的值

我有一个SalesOrder对象，它是从ReadResponse转换而来的，如下所示：

SalesOrder salesOrder = ((SalesOrder) response.getRecord());

for(CustomFieldRef field: item.getCustomFieldList().getCustomField()){
        _console.info(field.getScriptId() + " : " + field.getInternalId());
}

如何访问附加到SalesOrder对象的各个行项目中的customfields值

到目前为止，我已经有了这个，如果我需要的值是一个正则字段，它将非常有效：

for(SalesOrderItem item: salesOrder.getItemList().getItem()){
    //etc...    
}

我还可以访问与行项目关联的所有自定义字段的名称/内部ID，如下所示：

SalesOrder salesOrder = ((SalesOrder) response.getRecord());

for(CustomFieldRef field: item.getCustomFieldList().getCustomField()){
        _console.info(field.getScriptId() + " : " + field.getInternalId());
}

如何使用这些返回值？或者我的路径根本不对？

问题是我必须将字段强制转换为适当的“自定义字段”类型才能访问“getValue（）”函数。像这样：

        //loop through custom fields for custom field data.
        for(SearchColumnCustomField field: fieldArray){
            //_console.writeLn(field.getInternalId() + " " + field.getScriptId());

            //Then we are at the [Custom Field internalId: 1855].
            if (field.getInternalId().equals("1855")){
                SearchColumnStringCustomField searchBodyField = (SearchColumnStringCustomField)field;
                couponCode = searchBodyField.getSearchValue();
            }
            //Then we are at the [Custom Field internalId: 681]
            if (field.getInternalId().equals("681")){
                SearchColumnStringCustomField searchBodyField = (SearchColumnStringCustomField)field;
                orderId = searchBodyField.getSearchValue();
            }
        }
