You can not depend on anything that begins with two underscores. Those are
private members. When you create the "build" version of your application,
they will change names and, I think, errors generated if you try to
reference them.
The official and proper way to access the data provided in a Data event is
to call e.getData(). In this case, that will return a map containing the
two members "columnIndex" and "ascending". The fact that it happens to be
called __data within the event object is irrelevant, could change at any
time, and you should not depend on that. Only access the data via its getter
method, getData().
This applies throughout qooxdoo, not just here. Don't attempt to access
private members. Ever. They're none of your business; that's why they're
called "private". :-)
