我有两个 glazedList 表，如下所示。通过单击第一个表填充第二个表时，我得到 IllegalStateException。

有谁知道为什么以及最好的解决方案是什么？

代码：

        // build the first table
        String[] propertyNames = retrievepropertyNames();
        String[] columnsLabels = retrievecolumnsLabels();
        TableFormat<Order> tableFormat = GlazedLists.tableFormat(Order.class,propertyNames,columnsLabels);
        SortedList<Order> orderSortedList = new SortedList<Order>(model.getOrderEvenList(),null);
        table = new WebTable(new EventTableModel<Order>(orderSortedList,tableFormat));

        // Configures the first table
        TableComparatorChooser tableSorter = TableComparatorChooser.install(table, orderSortedList, TableComparatorChooser.SINGLE_COLUMN);
        tableSorter.appendComparator(1,0,true);
        table.setSelectionMode(ListSelectionModel.SINGLE_SELECTION);
        table.setAutoResizeMode(WebTable.AUTO_RESIZE_ALL_COLUMNS);
        table.setAutoscrolls(true);
        table.addMouseListener(retrieveTableMouseListener());
        table.getModel().addTableModelListener(retrieveTableModelListener());

        // In the same way as above i build the second table


        private MouseListener retrieveTableMouseListener()
        {
            return new MouseAdapter()

                    model.retrieveAllItems(vo.getId(),nr);//At this point i'm filling second table
                }
            };

When using EventList in multi-threaded environment, you need to obtain the lock before accessing the EventList.

Something like :

orderitemEvenList.getReadWriteLock().writeLock().lock();
try {
  orderItemEvenList.clear();
  for(Item Item:list){
     orderItemEvenList.add(Item);// this is eventList of second table
  }
} finally {
  orderitemEvenList.getReadWriteLock().writeLock().unlock();
}
