• init (scripted)

  #
  # Warn about potentially dangerous names, shadowing global

  # should be always executed), since this method might be executed
  # several hundreds of times for a view instantiating a high number
  # of workflow instances. Maybe we should define a developer-mode
  # defining this and more other calls via mxin classes.
