Glazedlist表的第一行中的IndexOutOfBoundsException？

Question

我已經構建了3個Glazedlist表。 當用戶點擊第一個表的行時，它會在第二個表中顯示列表。 當單擊第二個表中的行時，它將替換第3個表中的其他列表。 問題是，當我單擊第一個表中的第一行時，有時會出現異常。

有沒有人知道為什么我會得到IndexOutOfBoundsException以及如何擺脫它？

碼：

// build the table
EventList<Treat> TreatEventList = summaryModel.getTreatEvenList();
String[] propertyNames = new String[]{"PlanId", "Number", "Type","dication","stimulation","dication2","Date","Outcome","rank","version"};
String[] columnLabels = new String[]{"pnr", "NBNR", "handeling","Supp","Stim1","Stim2","date","Outcome","Rank","Version"};
TableFormat<Treat> tableFormat = GlazedLists.tableFormat(Treat.class, propertyNames, columnLabels);
SortedList<Treat> TreatSortedList = new SortedList<Treat>(TreatEventList, null);
cabinaTable = new WebTable(new EventTableModel<Treat>(TreatSortedList, tableFormat)); 

// Configure the Table
TableComparatorChooser tableSorter = TableComparatorChooser.install(cabinaTable, TreatSortedList, TableComparatorChooser.SINGLE_COLUMN);
tableSorter.appendComparator(1, 0, true);
cabinaTable.setSelectionMode(ListSelectionModel.SINGLE_SELECTION);
cabinaTable.setAutoResizeMode(JTable.AUTO_RESIZE_ALL_COLUMNS);
cabinaTable.addMouseListener(new MouseAdapter() {
    @Override
    public void mouseClicked(MouseEvent e) {
        int row = cabinaTable.rowAtPoint(e.getPoint());
        DHDPnr = cabinaTable.getValueAt(row, 0).toString();
        //at this point i set the evntlist for second Glazedlist table
        summaryModel.retrieveAllPredomainWithDHDPnr(dosNr(), DHDPnr);
    }
});

Answer 1

當用戶點擊第一個表的行時，它會在第二個表中顯示列表。 當單擊第二個表中的行時，它將替換第3個表中的其他列表

這給了我一個提示，你可以使用基於1的索引而不是基於0的索引，當嘗試訪問索引為0的空ArrayList時也會導致IndexOutOfBoundsException 。

Answer 2

很難用顯示的代碼告訴你，但是當你點擊第一行並且它試圖獲取數據時，代碼中的某個地方就沒有數據了。 因此，當您填充應該存在的數據時，由於某種原因，它不會這樣做。 通過查看所有代碼會更容易分辨，因為我之前沒有使用過GlazedLists。

大小：0表示它錯過了填充數據或某些內容為空。
