Hi, Has anyone ever built a plug-in that allow us to populate the doc

This sounds like a tricky design problem. It is probably possible to guage whether your chaining will break if you can estimate how many documents will be generated, and if you feel the wait would end up being too long then have an alternative path laid out for the user to understand that their request will take longer than chaining would allow.

What would be a really useful tool would be if you had your document generation jobs run asyn to your user process and present a 'Please Wait' form for the user. In the 'Please Wait' form you'll need to write a script that can ping the document generating process to know if it has finished or not so it can proceed to a kind of Review Results form. I haven't implemented such a design myself, but its one I'm keenly interested it.
