[MacRuby-devel] Overriding +autosavesInPlace

[Sven A. Schmidt]

Yes, that's what I was suspecting and the "self." prefix was exactly what I was missing :) (And I just noticed "YES" is not available in MacRuby.)

The following works then:

  def self.autosavesInPlace
    return true
  end

Thanks,
Sven
