Yes, why not. The updater could be written like:
html updater
id: TheTabTestPanel id;
callback: [:r |
r withOwner: anotherComponent do: [
anotherComponent add: (SUCounterTest new) label: 'another'.
anotherComponent renderBodyOn: r ] ]);
with: 'AJAX add from nested SUCounter' ]
The question is rather, if I want to explain that to anybody ;-)

The latest version of Slime detects that kind of bug. Thanks for the idea.
