当我想要洗牌时,FilteredList我得到一个java.lang.UnsupportedOperationException.

怎么办呢？

码:

FilteredList<Card> filteredData = 
    new FilteredList(ob, filterByOption(option.get("selectedCard"), option.get("chapter")));

if (option.get("cardOrder") == "shuffle") {
    filterCards=filteredData;
    FXCollections.shuffle(filterCards);
}
