I ran into a surprise today, and I'm not sure if it's by design or accident that I saw it. In Pharo-2.0, if I'm in Nautilus looking at class side definitions, and I click on the class to Refactoring -> Class Refactoring -> Generate Subclass..., I find that a subclass is attempting to be created on MetaObject, which fails due to not understanding the #category message. This is not the same behavior as happens when looking at instance side, which created a named subclass of the class. If this is wrong behavior, I will open an issue. If this is something that surprised me because I'm new, I'd be happy to hear a rationale, and I will open an issue, since the option fails, it should either not be present, or not send category. I guess I'd just like to know what the expected behavior is when creating a subclass and viewing class side in the browser. Thanks, Daniel Uber
