My application's JFrame logic looks like:

```
public Table() {
    super("Chess");
    thisFrame = this;
    tableMenuBar = new JMenuBar();
    populateMenuBar();
    setJMenuBar(tableMenuBar);
    getContentPane().setLayout(new BorderLayout());
    chessBoard = new Board(new StandardBoardConfigurator());
    gamePanel = new GameHistoryPanel();
    chatPanel = new ChatPanel();
    takenPiecesPanel = new TakenPiecesPanel();
    boardPanel = new BoardPanel(chessBoard);
    gameProgress = 1;
    highlightLegalMoves = true;
    moveLog = new ArrayList<Move>();
    gameOver = false;
    getContentPane().add(takenPiecesPanel, BorderLayout.WEST);
    getContentPane().add(boardPanel, BorderLayout.CENTER);
    getContentPane().add(gamePanel, BorderLayout.EAST);
    getContentPane().add(chatPanel, BorderLayout.SOUTH);
    // Make sure we have nice window decorations.
    setDefaultLookAndFeelDecorated(true);
    setDefaultCloseOperation(EXIT_ON_CLOSE);
    setSize(OUTER_FRAME_DIMENSION);
    pack();
    setVisible(true);
}

```

and the `JPanel` containing the JTable is 'GameHistoryPanel', which has this as it's constructor logic:

```
    public GameHistoryPanel() {
        this.setLayout(new BorderLayout());
        this.model = new DataModel();
        this.table = new JTable(model);
        this.table.setRowHeight(15);
        final JScrollPane scrollPane = new JScrollPane(this.table);
        scrollPane.setColumnHeaderView(table.getTableHeader());
        scrollPane.setPreferredSize(HISTORY_PANEL_DIMENSION);
        this.add(scrollPane, BorderLayout.CENTER);
        this.currentRow = 0;
        this.currentColumn = 0;
        this.setVisible(true);
    }

```

The `GamePanel` has the following update routine which calls `setValueAt` whenever a move is made:

```
    public void increment(final Board board,
                          final Move move) {
        this.model.setValueAt(move, currentRow, currentColumn);
        if(board.currentPlayer().getAlliance() == Alliance.WHITE) {
            currentColumn++;
        } else if (board.currentPlayer().getAlliance() == Alliance.BLACK) {
            currentRow++;
            currentColumn = 0;
        }
    }

```

Upon launching the game, the `GamePanel` is grayed out. When I resize it *vertically*, it suddenly appears with all of the correct values. I don't understand why. I did notice that resizing causes `getValueAt` to be invoked a bunch of times. Can someone help me understand this?

**EDIT 2**: If I add this line:

```
        this.model.fireTableDataChanged();

```

to increment, it seems to work fine. I'm wholly confused...

EDIT: Here is my TableModel class:

```
    private static class DataModel extends AbstractTableModel {

        private static final String[] names = {"White", "Black"};
        private final List<Row> values;

        public DataModel() {
            values = new ArrayList<Row>();
        }

        @Override
        public int getRowCount() {
            return values.size();
        }

        @Override
        public int getColumnCount() {
            return names.length;
        }

        @Override
        public Object getValueAt(int row, int col) {
            final Row currentRow = values.get(row);
            if(col == 0) {
                return currentRow.getWhiteMove();
            } else if (col == 1) {
                return currentRow.getBlackMove();
            }
            return null;
        }

        @Override
        public void setValueAt(Object aValue, int row, int col) {
            final Row currentRow;
            if(values.size() <= row) {
                currentRow = new Row();
                values.add(currentRow);
            } else {
                currentRow = values.get(row);
            }
            if(col == 0) {
                currentRow.setWhiteMove((Move) aValue);
            } else  if(col == 1) {
                currentRow.setBlackMove((Move)aValue);
            }
            this.fireTableCellUpdated(row, col);
        }

        @Override
        public Class<?> getColumnClass(int col) {
            return Move.class;
        }

        @Override
        public String getColumnName(int col) {
            return names[col];
        }
    }
}

```
