Multiple roots

[kuraga]

Hello! Next issue I want to attent is multiple roots issue.

We have a 'widget's root' termin: root of widget is its (sub)parent with nil parent (see here). Apotomo uses widgets' roots: here and here.

And widget is a root for itself after removing.

By other side we have (one only) request_processor.root: see here.

So, there are multiple roots in some situations.

Consider one (bad) situation. Consider widget (with awesome_root root) is responding to an event. According to this results of triggers go to widget.root.page_updates (awesome_root.page_updates). Suppose widget has been removed during responding. Then (according to this) widget.root is widget; and widget.root.page_updates is widget.page_updates but not awesome_root.page_updates. So, the result (page_updates) of respond is wrong.

You thoughts?

Can you further describe how such a situation can be created? There should be only one root instance during the entire controller run.
