The last question Greg.
When I create a new Component, how I do to display it in the windows.

Thank you

I think I see the problem. When an instance of TablePane.Row is created, it
is empty (i.e. it has length 0). Since TablePane#setCellComponent() calls
update() on the row, you get an IndexOutOfBounds exception because there is
no cell at that index to update.

I had actually forgotten about this method, and it should probably be
removed from the platform for this reason. The best way to construct a
TablePane dynamically is to create all of your columns, then use the add()
method to create and populate the rows:


    TablePane tablePane = new TablePane();

    // Add 3 columns
    TablePane.ColumnSequence columns = tablePane.getColumns();
    columns.add(new TablePane.Column());
    columns.add(new TablePane.Column());
    columns.add(new TablePane.Column());
    
    TablePane.RowSequence rows = tablePane.getRows();

    for (int i = 0; i < ROW_COUNT; i++) {
        TablePane.Row row = new TablePane.Row();
        rows.add(row);
        
        for (int j = 0; j < columns.getLength(); j++) {
            // Add cell for column j
        }
    }
