我已经建立了 3 个 Glazedlist 表。当用户单击第一个表的行时，它会在第二个表中显示列表。当单击第二个表中的行时，它会显示第三个表中的其他列表。问题是当我单击第一个表中的第一行时，有时会出现以下异常。

有谁知道为什么我会得到 IndexOutOfBoundsException 以及如何摆脱它？

代码：

// 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);
    }
});

当用户单击第一个表的行时，它会在第二个表中显示列表。当单击第二个表中的行时，它会显示第三个表中的其他列表

这给了我一个提示，您可以使用基于 1 的索引而不是基于 0 的索引，这也会导致IndexOutOfBoundsException尝试访问索引为 0 的空 ArrayList。

用显示的代码很难分辨，但是当您单击第一行并尝试获取数据时，代码中的某处没有数据。因此，当您填充应该存在的数据时，出于某种原因它并没有这样做。因为我以前没有使用过 GlazedLists，所以通过查看所有代码会更容易判断。

Size: 0 表示它错过了填充数据或某些内容为空。
