@Override
public void setHelp(MenuItem item, String contextId) {
  if (WorkbenchPlugin.DEBUG)
    setHelpTrace(contextId);
  item.setData(HELP_KEY, contextId);
  // ensure that the listener is only registered once
  item.removeHelpListener(getHelpListener());
  item.addHelpListener(getHelpListener());
}
