Hmm, indeed, evaluating the Velocity code from the document title

More info:

/xwiki/rest/wikis/xwiki/pages so there's clearly an inconsistency.
Thanks,

I see what you mean but we're only talking about velocity evaluation
here, which is not exactly "presentation". On Fri, May 11, 2012 at 2:31 PM, Marius Dumitru

I think the "title" page REST resource property should provide the raw
document title on the long run, and the rendered title could be
obtained through http://jira.xwiki.org/browse/XWIKI-5820 . So I don't
see other solution besides:
But this means that in order to get technical
info about a page
(parent, children, etc) and the rendered title you'll need to make 2
requests right ?
No. If you need only the rendered version of a page you request
directly the rendered version, which includes all the document meta
data (parent, child, etc.). The only difference is that fields like
title and content which are "renderable" are rendered. At least that's
what I understood from http://jira.xwiki.org/browse/XWIKI-5820 . Now,
if you need both raw and rendered data you have to make indeed 2
requests.
Is the raw title really useful outside of an
editor ?
As I said before, I believe the data is more important than the
presentation of the data and REST should focus on the data first, i.e.
it should expose XWiki data. Right now you can't access the raw
document title through REST and this is a serious limitation.
I don't know if there are more use cases for the rendered title versus
raw title, but I know that you can get the rendered title from the raw
title, but not the other way around. Someone might want to use his own
renderer for the title (although that's a bit far fetched :) ).
You can get the rendered title from the raw title only of you're using
the API from XWiki itself (and on the server side).
