If you set "self.status", it *shadows* any value that was set on the class. Hence, you'll have a value set on the class *and* a value set on the instance. That's not going to help you if you're looking for the status in the wrong instance ;) If ClassName.status didn't work, I'm worried that's because you're using another instance of ClassName that has it's own version of status that's also shadowing ClassName.status.
