Buggy source:

  boolean ba=false;
  if (e.getSource() == add) {
    int a=v.size() + 1;
    this.v.add(new ScheduleFrame("String_Node_Str" + a));
    reloadList();
    SwingUtilities.updateComponentTreeUI(this);
  }
  if (e.getSource() == remove) {
    try {
      ScheduleFrame s=(ScheduleFrame)v.elementAt(list.getSelectedIndex());
      this.v.remove(list.getSelectedIndex());
      this.reloadList();
      this.status_panel.removeAll();
      renameLabels();
      SwingUtilities.updateComponentTreeUI(this);

Fixed version (ground truth):

  if (e.getSource() == add) {
    int a=v.size() + 1;
    this.v.add(new ScheduleFrame("String_Node_Str" + a));
    reloadList();
    SwingUtilities.updateComponentTreeUI(this);
  }
  if (e.getSource() == remove) {
    try {
      ScheduleFrame s=(ScheduleFrame)v.elementAt(list.getSelectedIndex());
      this.v.remove(list.getSelectedIndex());
      this.reloadList();
      this.status_panel.removeAll();
      renameLabels();
      SwingUtilities.updateComponentTreeUI(this);
    }
 catch (    Exception ex) {
    }
  }
  if (e.getSource() == show) {
    try {
      int item=this.list.getSelectedIndex();
      ScheduleFrame sched;
      if (visible == false) {
        this.status.stop();
        this.status_panel.removeAll();
        sched=(ScheduleFrame)v.elementAt(item);
        visible=true;
        this.status_panel.add(sched);
