Brent Perkins - Could you confirm which version of Jive you are using?
Of all the versions I have used, you cannot create duplicate documents in the same container/place with the same subject. So this is a real restriction in both the UI and the API for documents only. As for other content-types, the only limitation that comes to mind is for blog posts with the same title on the same date (as it violates the permalink implementation).
When I try to do this (for example in this community), I get the following error:
The title of this document is not unique among the documents in the space
If your instance isn't honoring this restriction then we need to dig into why that is the case.
Let us know if you continue to see this problem.
Thanks for the quick reply. I went back to duplicate this and it appears that I had made an error and didn't type the upper/lower case exactly the same in both test cases. All is right with the universe after all. Thanks!
