on deleteGroup

[David Bovill]

It's an issue for anyone developing nested components. In my case I have a
component that I want to distribute that creates some (global) data that I
want to tidy up / clear when the component is deleted manually or by script.
This is fine if the group is a top level group, but as i use "layout groups"
and other forms of group nesting (say I want to use the group within a
datagrid for instance) - then no message at all is sent - and so I cannot
create this form of component without resorting to libraries or front/back
scripts.

I've filed this as a report here (and copied Trevor's description)  -
