Problem showing imageicon in cell using TableCellRenderer

Question

Hi all,
I am using a tablecellrenderer to display an icon in a particular jtable column to reflect a value in the underlying model.
When I do this, the column does not display the ImageIcon at all. My code for the CellRenderer is below.
It should also be noted that I use another table cell renderer on the whole table to remove the line around the selection on the selected cell. This all works fine.
public class StatusCellRenderer implements TableCellRenderer {
    private static ImageIcon blueIcon = new ImageIcon("images/blue.gif");
    private static ImageIcon redIcon = new ImageIcon("images/red.gif");
    private JLabel label = new JLabel();
    // Constructors
    public StatusCellRenderer() {
        label.setHorizontalAlignment(JLabel.CENTER);
        label.setVerticalAlignment(JLabel.CENTER);
    // TableCellRenderer interface implementation
    public Component getTableCellRendererComponent(JTable table,
    Object value,
    boolean isSelected,
    boolean hasFocus,
    int row,
    int column) {
        if (Integer.parseInt(value.toString()) > 0){
            label.setIcon(blueIcon);
            label.repaint();
            return label;
        else if (Integer.parseInt(value.toString()) == 0){
            label.setIcon(redIcon);
            label.repaint();
            return label;
        else
            return null;
}

Answer 1

First question: What do you see in the column where you expect the Icon?
First suggestion: extend DefaultTableCellRenderer instead of implementing TableCellRenderer interface. Just a suggestion.
second question: Have you set the renderer for the class of objects in target column to be the StatusCellRenderer?
As camrickr says you need to post a little more code. Maybe a SMALL demo program illustrating your problem. Use code tags for legibility.
