Thanks Branden (and Bert)!
Branden your tips for returning items worked on 1.1 and 1.3 and your
tip on retrieving version content on 1.3...seems like something
changed tho between 1.1 and 1.3 because retrieving version content
with an URL in that form returns a 500 in 1.1, as per below.
Any ideas on a URL to retrieve version content in 1.1? Sorry to be
asking about old versions...
Internal Server Error (500)
The requested URL /p/m5g95Ejui/id1995724.version.,1.1,.json resulted
in an error in org.sakaiproject.nakamura.version.impl.GetVersionServlet.
Exception:
