Well, you can verify it by printing 'list(binding.iterParents(self))'.  If 
your Commands object isn't in the hierarchy, that would certainly indicate 
the issue.

Anyway, by default, a command will be made a child of the invoking 
command's 'getCommandParent()' method.  Unless you've overridden that 
method, it should return 'self'.  So I'm not sure what's going on here.  So 
the next step is to check what the actual parent objects are.
