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
}
}
