Subject Re: an aggregate object
Date Mon, 12 Apr 2010 21:44:21 GMT
I considered that. I didn't really give the full extent of what i need
to do. Each of my "related docs" might itself be a group of documents.
I want to save all changes to documents as new documents in the
aggregate group:

so if the group is:  docA, docB, and docC
then i might have docC1 and docC2

when the user edits docC i'd rather not have to go back to all the
other docs in the group and update their "related_docs" field... i'd
like to have a field in the new document that makes it part of the
"family" without have to update all the other documents in the family

thanks for the idea though
