I have a labelCellRender for a JTable, because I want to display an
imageIcon depending on something. Everything works fine except that when
I select the cell, the selectionColor does not show, so you can�t see
which cell is being selected.
The code of the labelCellRender is as follows:

  class labelCellRenderer  extends JLabel implements TableCellRenderer {

     public labelCellRenderer() {
          super();
      }
     public Component getTableCellRendererComponent(JTable table,
                                         Object value, boolean
isSelected,
                                         boolean hasFocus,
                                         int row, int column){

     if(value==null) { return this;}
     if(value instanceof Detail) {
        Detail detail = (Detail)value;
        int level = detail.getLevel();
        String description = detail.getDescription();
        setText(description);
        this.setIcon(image[level]);}
      }
}

what�s wrong? Could any body help me?
Thanks
