我有一个包含可变列表的对象

object TrackingEventsList {
    var EventDate: String = ""
    var EventDescription: String = ""
}

object Waybill {
    var WaybillNumber: String = ""
    var OriginHub: String = ""
    var TrackingEvents: MutableList<TrackingEventsList> = ArrayList()
}

当我尝试添加Waybill.TrackingEvents时,所有先前的实例都被覆盖并复制添加的最后一个TrackingEvent.

private fun fillTracking(events: NodeList) {
    var list = TrackingEventsList
    for (x: Int in 0 until events.length) {
        var tName = (events.item(x) as Element).tagName
        var event = (events.item(x).firstChild as Text).wholeText
        if (tName == "EventDate") {
            list.EventDate = event
        }
        if (tName == "EventDescription") {
            list.EventDescription = …
