Hi everyone,
Let me wish everyone a Merry Christmas 2016 and a Happy New Year.
May you continue to use XWiki in 2017!
And let’s make 2017 the year when XWiki takes the world by storm… :)
Thanks

Hello,
I recently loaded ~3000 pages into my XWiki (8.2.1) instance. And noticed a
enormous increase in loading times of DocumentTree in my custom navigation
panel, which shows the pages under first level of space hierarchy:
#set( $root = $doc.getDocumentReference().getSpaceReferences().get(0).
toString().replaceAll('([~"])', '~$1').replace("Space ", "document:") +
".WebHome")
{{documentTree showTranslations="false" root="$root" showRoot="true"
showAttachments="false" /}}
Before loading the pages each request took around ~600ms. After adding the
pages load time was around 15 seconds. After bit of googling I found the
JIRA issue:
http://jira.xwiki.org/browse/XWIKI-13700
<http://jira.xwiki.org/browse/XWIKI-13700>
And decided to upgrade to 8.4.3. However, the issue did not get fixed and
there was no change in load times. Turning on debug prints for hibernate
resulted in the following:

*org.hibernate.ObjectNotFoundException: No row with the given identifier
exists: [com.xpn.xwiki.doc.XWikiDocument#-8266574047497816716]*So my guess
is that hibernate fails to load the entities and has to load each entity
multiple times? Is this result of a corrupt database due upgrade or
something else? This error repeats multiple times for each DocumentTree
loading ( and also some other resources ).
I have also tried to increase the amount of documents cached.
Any help is appreciated.

Hi,
I modified the Navigation panel menu in order to have a structured tree menu
that always shows FOO page root and the opened path to reach the current
node (FOO project has nested pages).
{{velocity}}
#panelheader("FOO MENU")
## Escape special characters in macro parameter values.
#set ($openTo = $services.model.serialize($doc.documentReference,
'default').replaceAll('([~"])', '~$1'))
{{documentTree showTranslations="false" showAttachments="false"
compact="true" showRoot="true" openTo="document:$openTo"
root="document:xwiki:FOO.WebHome" /}}
#panelfooter()
{{/velocity}}
Considering all my projects are inside Main\projects page, is there a way to
find dinamically the toplevel page node without having to specify the root
page name (FOO.WebHome)?
Thanks for reply
-Matteo

We have editors that modified wiki pages and used the comment option that goes with a version.
But when viewing version history we see some comments ending with."..."
This suggests that the rest of the comment is in the database, but not viewable by the version history table
Is there a way to view the full comment made with a version
Is there a maximum text size for version comments

Hi,
I am having issues when tring to link to headings in pages with markdown.
The regular syntax (which we'd have to keep, or at least keep as basis)
for this would be [link name](#headingId).
When markdown gets parsed for xwiki, ID's are being generated for the
headings, and if the id-codes are known it is a simple matter of linking
to those, however, this becomes a near impossibility to do
beforehand. Since we'd like to avoid having to re-edit every single page
after sending a markdown page to the api, we would like to keep
this quite simple syntax, since the only workaround we could do was
insert html tags at appropriate places - however these are not evaluated
when the document is parsed with markdown.
Plus, when I use a Link to #page, xwiki will try to link to a page
named %23page instead of linking to the heading "page".
So the question is - is there a way to keep the simple markdown-syntax,
or change it slightly, to link to a heading within this page?
