I've found it possible however to add hooks in newforms to be able to perform stuff after related objects are saved. newforms-admin branch is required to make it work in admin. I should perhaps write about it somewhere.. As a lot of other people I’ve also come across this problem.

Thanks for the feedback! Perhaps, I have tried using the post-save signal and it definitely runs before the children get processed.

The issue is that his code is executing after the parent object is saved, but before his child objects are saved, so they're written right over the top of whatever his code does. From what I can tell from the docs, the 'post_save' signal does the same thing. You could listen for post_save signals from each of the child objects, but then your code runs once for each of them, and there's no good way to know you're looking at the last one. IMHO, the best shot might be to try to hook it into the admin. I don’t really think signals are going to help.
