Hi Anthony,
first of all, thanks a lot for your interest in databinding and for your
effort in designing your own code in such a way that it might be used to
extend the databinding framework itself!
I only had a look at your blog post for now and since I will be on
holiday for two weeks I might not get into having a closer look at the
actual implementation. However, at first sight, it seems to me that what
you're doing might be related to the following bug:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=300043
The bug proposes some sort of "reducer API" which I think could also be
used to implement the type of aggregations you are proposing (e.g. as a
special implementation of a ListReducer). There's a tentative patch by
Matthew Hall attached to the bug so you might want to have a look at it.
In any case, I will have a look at your implementation but I cannot
really guarantee that it will be before my holiday...
Regards,
Ovidio
