  Hi, I am a newcomer to Xwiki.
 I want some page created to be based on a template and so I created
 class and class sheet. It works, but if I put a link in page A  (based
 on template) to page B, this link is not referenced in backlinks of
 page
 B. If page A is not based on template, the link is referenced.
 What is wrong? 
I think this is a limitation. Right now backlinks are saved the
document is saved. Since your document A is actually an object, maybe
the document isn't saved in the same way. That would need to be
verified and tracked.
Could you please open a jira issue at 
http://jira.xwiki.org?
Thanks
