Well, let's think about it. "Instance variables" are only accessible as long as you have an instance, right? You can't have an instance variable without an instance. So if you set "self" to nil... then you no longer have an instance. Thus, you cannot access self's instance variables, because there is no self.
Sorry I don't have a doc link for you; perhaps someone more well-versed with the documentation search tools than I can find something relevant. :) Dave On Jul 28, 2011, at 2:45 PM, Mr. Gecko wrote: > That makes lots of sense, never even expected that to happen.
