Regardless, they still said _root is bad, _levels or not. That’s probably one of the reaonses they redid some of the core components (just one not all) because a few relied, wrongfully so, on _root.

I would assume that if you are not allowed to reference _root that our Central products are NOT being loaded into leveles. Each level has it’s own root remember. Read my responses to the article here:

Here’s part of a response from Kevin Lynch:

—

The way this works in Central is that apps from different domains exist
in separate _global spaces, as part of the security sandbox design. So,
you don’t need to worry about colliding with applications from other
domains.

The thing you do need to worry about is colliding with other apps from
the same domain, which can happen if the user decides to run several of
your applications at the same time (for example, in two windows). So,
you should declare a global for each of your apps, like _global.FooApp
and _global.BarApp and that should do it. You could use the longer
_global.com.yourdomainname.yourappname.yourobject for this if you like
of course.
