Objet : [xwiki-users] XWQL query on several objects of the same class 
instantiated in the same doc
Date : mer., mai 22, 2013 21:24



Louis-Marie, Edo, thanks again!

Louis-Marie, you perfectly understand what I'm trying to get: to use comments 
on documents as criteria for selection. I understand comments are not intended 
to satisfy this objetive, but, at least for me, they are extremely useful to 
"draft" data models to be implemented in new XWiki classes. Just a kind of 
"extreme development" tool! :-) I think the "only" problem we are facing with 
this use is the kind of queries combining comments on the same document to 
retrive documents and properties of any class there instantiated.

I'm truly learning a lot! I think I can understand the construction and it must 
answer the well-formed question Louis-Marie wrote down in his message, but I'm 
not able to understand the result. Here what I get...

org.xwiki.query.internal.DefaultQuery@70687068

The integer after the @ changes it time I reload the page. I din't get neither 
a document fullName, nor an object.

You can always check it in the same link posted before...

http://www.idisantiago.es/bin/XWQL/SnapshotE0012012

In found DefaultQuery code here...

http://maven.xwiki.org/site/clover/20120701/clover-platform-20120702/org/xwiki/query/internal/DefaultQuery.html

Perhaps this construct doesn't work in my plain old XWIKI ENTERPRISE 2.4.30451 
installation?

Thanks for your help!

Ricardo

Re: [xwiki-users] FW: Scheduler

[BOUSQUET Jeremie]

I will try to reinstall it ... In fact I installed the Scheduler as an 
application in XE 1.1, then migrated to XE 1.2, so I'll reimport it to be sure.

There's no virtual wiki, it's the standard XE.

Re: [xwiki-users] FW: Scheduler

[BOUSQUET Jeremie]

Hi,

The scheduler does not work ! ;-)

Regarding the remarks below, I'm using the Scheduler packaged with XE 1.2.

But I get the following error :

org.quartz.JobExecutionException: The user [XWiki.Admin] didn't have 
programming rights when the job [xwiki:Scheduler.JOBTimeLineFeed_0] was 
scheduled.
[...]

But :
- Admin account exists, as well as profile XWiki.Admin
- of course, it has admin&programming rights
- my job page was saved by the admin

So I don't understand why it does complain about missing programming rights ! ?

Thanks,
Jeremie

Then there's a problem with the Scheduler/Watchlist applications, as 
they contain documents saved by Admin. If a wiki does not contain this 
account, then nothing will work. What we can do:

1. Save them as superadmin.
2. Write in the installation guide that if if there is no Admin user, 
then all the files must be manually saved by an user with programming 
rights.

I'd go with 1, as most people don't read the Installation guide, and 
they'll just post on the mailing list that the scheduler does not work...

Can somebody take care of this?

Re: [xwiki-users] [XE 1.2.2] Space characters trimmed inattachmentnames

[BOUSQUET Jeremie]

Undeletable attachments give some work to the admin, problems of attachments 
and images names are easily workaround by asking users not to use special 
characters in names ... While trimming spaces impacts all users and anyway you 
have to ask them to take care of resulting name of their attachments ...
That's why I'm not sure it's better than the blocking-in-some-specific-cases 
issue ... :)

Well this temporary fix isn't perfect but still better than the
blocking issues that were raised before : undeletable attachments,
unembeddable images, etc.
BTW may be we should clear the name but keep the spaces (which aren't
a problem), wdyt ?

The use of the clearName method for attachment names is a temporary
fix until the resolution of all our encoding issues.

Yes this is a drawback of this fix.

[xwiki-users] [XE 1.2.2] Space characters trimmed in attachment names

[BOUSQUET Jeremie]

Hello,

 

Don't know if it's a bug or an evolution, but after migrating my xwiki
to 1.2.2, when I attach a new file to a page, all spaces characters are
trimmed from the name. I didn't found anything about that in Jira.

For example "My Doc Attached.doc" gets renamed to "MyDocAttached.doc".

 

I see at least one issue coming from this : if you attach the same file
it's not considered the same because it's renamed. Your existing links
also link to the previous version, and it's not easy to find by
end-user.

And anyway you don't want the file to be renamed when attached ...

 

I'm using XE 1.2.2 on MySql 4.0 and RedHat R4.

 

WDTY ?

 

Thanks,

Jeremie

Re: [xwiki-users] MySQL Error "invalid use of group function" in Statistics application

[BOUSQUET Jeremie]

Sergiu,
I must admit that your solution is the more efficient and clean, even if I 
personally don't like it (you'd be surprised to know how painful it will be to 
ask my infra team to upgrade mysql version ...).
For me it's clearly a MySQL bug not an hibernate one, let's say at least a 
break of compatibility in MySql not managed by hibernate. Typically what you 
would like an abstraction layer to take care of ... :/

Thanks for help,
Jeremie

Generally, we should stay away from pure SQL as much as possible. If the

 Hi Jeremie,

 The sql query you suggested is cleaner and at least as efficient as the
 current one. It was my first option but unfortunately it's not
 supported
 by the newer versions of mysql. I've no idea why..

 mysql> select xws_name, sum(xws_page_views) as pageviewcount from
 xwikistatsdoc where xws_action='view' and xws_name like '%.%' group by
 xws_name order by pageviewscount desc;
 ERROR 1054 (42S22): Unknown column 'pageviewscount' in 'order clause'

>>> Note that there's a typo: pageviewcount <> pageview-S-count

 Anyway, hibernate should be responsible for the correct translation
 from
 hql to a specific sql dialect. A solution would be to use the (idea
 from
 the) above sql but configure the dialect to MySQL5Dialect (in my case).
 I
 have to test this. I'll give you feedback soon.

 Marius.

Hi Marius and thanks,

Your SQL request returns the same error "invalid use of group function" in my 
mysql version ...

BTW I could have it work by explicitly naming the sum, and using it in the 
order by :

select xws_name, sum(xws_page_views) as pageviewcount from xwikistatsdoc where
xws_action='view' and xws_name like '%.%' group by xws_name order by
pageviewscount desc
 
I believe it's a difference in behaviour between MySQL 1.4 and 1.5 ... Do you 
want me to create a JIRA issue for this ?

Hi Jeremie,

Sorry for the inconvenience. Your tables' description seems fine. I
attached the description of my tables so you can check it for yourself. I
think it all resumes to the following SQL query:

select xws_name, sum(xws_page_views) from xwikistatsdoc where
xws_action='view' and xws_name like '%.%' group by xws_name order by
sum(xws_page_views) desc

This query is very similar to the one used for retrieving the Most Viewed
Pages. It works fine under:

mysql  Ver 14.12 Distrib 5.0.45, for pc-linux-gnu (x86_64) using readline 5.2

It would be great if you could run this query and tell me if it works in
your case.

Re: [xwiki-users] Problems with Lucene lock (IOException) ...

[BOUSQUET Jeremie]

Thanks,

 

After shutdown, delete of .lock and restart, the file has been recreated.

 

But I still have a whole bunch of very ugly exceptions, I think I will have the 
server reboot because some handles might still be somewhere ...

 

@Vincent : I'll try to perform the migration on final 1.2 release ASAP anyway. 

 Thanks again,

Here's a few avenues to solve that:

- shutdown your servlet container, see if the file is still there

- remove the file by hand...

 

I believe this is the result of a crash but I thought that Lucene had a way to 
solve that in newer versions. 

 

We have moved to the latest lucene 2.3.0 in 1.2.1.

In older versions of Lucene, for our ActiveMath platform, I used a different 
locking mechanism which waits ten seconds and if no attempt-to-lock is removed 
it is considered we can safely override the lock. Not very elegant.

Re: [xwiki-users] No document found in the selected archive...

[BOUSQUET Jeremie]

Hi,
 
You might want to check inside your generated .xar archive that there
are no empty (0 size) documents. It can be due to problem during .xar
export (some pages fail to export).
This used to make the import process fail in older versions, I don't
know if it's still the case.

[xwiki-users] Groovy and getXMLEncoded() question

[BOUSQUET Jeremie]

Hello,

 

I'm having a headache trying to understand why those 2 pieces of groovy
do not generate exactly the same thing :

 

1)-

<%

// LOOP 10 times

  println ( '' + xwiki.getXMLEncoded(blablabla) + '' )

// END LOOP

%>

 

2)-

<%

str = ''

// LOOP 10 times

  str  = str + '' + xwiki.getXMLEncoded(blablabla) + '\n'


// END LOOP

println(str)

%> 

 

"blablabla" is a formatted text (in my case, the description field of an
article for example).

 

1) produces what is expected : it writes 10 lines of text, beginning
with '', and special characters in "blablabla" are correctly
translated.

 

2) produces any number of lines (> 10), because carriage returns inside
"blablabla" have not been translated, and so many lines are written for
each line expected.

 

I 'm not sure if this is the right place for this, but if someone as an
idea it would greatly help me ...

 

 

Best Regards,

Jeremie

I think it should also work in 1.1.X (I'm doing this). What I'm sure do
not work without a fix in 1.1 is the wiki-prefixed panel inclusion.
Are the users from the sub-wikis allowed to view the skin ?

I'm almost certain I used XEM 1.0M3, and inside it was XE 1.2 but RC2 or RC3 ...

Hi,

Are you sure you use the M3 and not the M2 ?
The M2 version has this bug and, about the other problem you have, is
based on XE 1.1

You can declare any wiki as "template" to be used for create other
wikis from. You can import an XE xar in an empty subwiki you created
and declare it as template in it's descriptor you can acces from
/WikiManager/WebHome.

Several answers:

1) Well, XWiki is an open source project and we're accepting  
contributions and even committers. So if anyone wants to improve and  
maintain something just create a jira issue and attach a patch to it.

2) Now that said, it's true that so far the core committers have only  
been maintaining one skin at a time and skins like dodo and finch are  
not currently maintained by the committers (only by the contributors).

3) What we'd like to do in the future is to extract common code in  
these 2 skins (albatross and the new one) and move that into templates  
in order to make creating new skins very easy and easy to maintain.

4) BTW this new skin is based on Albatross templates so all templates  
will be maintained de facto. The main different thing is the CSS.

Seen these answers, I think the answer is probably yes but then it'll  
eventually depend on the committers and the community's help.

Thanks

Hi,

The new web site is really fine, and the virtual wiki mngt is very interesting 
... ;)

I'd like just to signal a rights management problem (I guess), as guest I can 
browse all virtual wikis from home page, but if I log in with my account I have 
no rights at all on pages in XWiki Watch wiki ... I still have rights on other 
wikis.

Re: [xwiki-users] Getting rendered content ofa pagewith aspecifictemplate

[BOUSQUET Jeremie]

 

In first instance I copied the sample (the timeline) in a WIKI page, but of 
course as in the sample are defined ,  and  tags, it could 
not work. In a wiki page we already are inside the  tag, and the browser 
does not like redefining such tags very much.


I have not a clear idea about how to have this kind of  and  nested 
tags affect the rendering of the page.
Take a look at this...
http://xepecnet.environmentalchange.net/xwiki/bin/view/ICT/GoogleMaps
Here the code...
http://xepecnet.environmentalchange.net/xwiki/bin/view/ICT/GoogleMaps?viewer=code&showlinenumbers=0&language=en
 and  are also defined in the Google Maps snippet, but the page is 
correctly rendered. No errors at all.



Ok, this means I was wrong ;) Maybe the difference is in the header (with the 


 

 So the trick was to have a page WikiDev.TimeLine, with the sample, another 
page WikiDev.TimeLineFeed with the sample script to generate the XML (it works 
well, I only added new things inside it). Basically the timeline feed page 
generates XML with a root  tag, and a number of  tags inside, with 
a date ("start") and a "description". So it's very easy to generate using any 
events as entries. In the WikiDev.TimeLine page you have to put URL of 
WikiDev.TimeLineFeed as first parameter of the tl.loadxml() method.


This is another point I fail at. I am not a programmer, so I have to learn how 
to produce this XML output from XWiki items.
Let's write down here a couple of simple examples showing the structure you 
describe...
http://simile.mit.edu/timeline/docs/example1.xml
http://simile.mit.edu/timeline/docs/example2.xml
And the HOW-TO from Simile...
http://simile.mit.edu/timeline/docs/create-timelines.html



The sample from Jeremi is quite simple and works very well to display all News 
elements in the timeline :

{pre}



#set($feed = $xwiki.feed.getFeed("$xwiki.getURL('Main.BlogRss', 'view', 
'xpage=rdf')"))

#foreach($entry in $feed.entries)

$xwiki.getXMLEncoded($entry.description.value) ... 
$xwiki.getXMLEncoded("Suite")



#end

 

Note : ADD CODE HERE TO ADD OTHER EVENTS IN THE XML

 



{/pre}



The #foreach parses all entries in the feed (constructed with your wiki blog), 
and writes down an  entry with date and description. It's not too 
complicated, but it's development ... In the ADD CODE HERE ...  , I put the 
groovy code to generate the XML from the page updates and the FAQ entries and 
such, but it's more complicated, not very readable, and most of all there are 
many hard-coded specific things inside it. Once I'll get something clearer I'll 
share it with you or add it in xwiki wiki ;-)

 

 

Then, in the page where I want to show the timeline, I added a , with 
"src" equals URL of WikiDev.TimeLine. Also had to give it a height and width 
for proper display. Inside the  it's like in another page, so there is 
no problem of  or  tags anymore. The WikiDev.TimeLine page does not 
show up (you get the URL prefiks error), but the  in the other page 
should display correctly.


The  way works perfectly. I am only still curious to understand why 
Google Maps work without it.
I am too (see above). I believe it would be nicer to be able to do as for 
Google Maps, but we would have to understand better why it works ...

 

Hope this helps ...


Yes, it does! Thanks for your message, Jeremi. I keep working to produce a 
clear page about how to use Simile TimeLine in XWiki, although I think you are 
the one for this task! :-)
If you prefer I can get the point ;-) But is this a code snippet, an 
application, macros ... ? I believe it belongs to snippets ... And can I make 
use of Jeremi's modified sample, because HE is the creator of this xwiki 
timeline after all 

 

Regards,

 


Cheers,

Re: [xwiki-users] Getting rendered content of a pagewith aspecifictemplate

[BOUSQUET Jeremie]

Hi Ricardo,

 

In first instance I copied the sample (the timeline) in a WIKI page, but of 
course as in the sample are defined ,  and  tags, it could 
not work. In a wiki page we already are inside the  tag, and the browser 
does not like redefining such tags very much.

 

I then tried the trick from the TIMELINE-24 issue also, but it failed to work. 
I don't know if I left this "patch" on the page, because my wiki is currently 
broken ... :/ It removed the URL prefiks issue, but nothing was displayed.

 

So the trick was to have a page WikiDev.TimeLine, with the sample, another page 
WikiDev.TimeLineFeed with the sample script to generate the XML (it works well, 
I only added new things inside it). Basically the timeline feed page generates 
XML with a root  tag, and a number of  tags inside, with a date 
("start") and a "description". So it's very easy to generate using any events 
as entries. In the WikiDev.TimeLine page you have to put URL of 
WikiDev.TimeLineFeed as first parameter of the tl.loadxml() method.

 

Then, in the page where I want to show the timeline, I added a , with 
"src" equals URL of WikiDev.TimeLine. Also had to give it a height and width 
for proper display. Inside the  it's like in another page, so there is 
no problem of  or  tags anymore. The WikiDev.TimeLine page does not 
show up (you get the URL prefiks error), but the  in the other page 
should display correctly.

 

Hope this helps ...

 

Regards,

 

 

Jeremie

I, of course, completely agree, as said I merely put 2 things together ;-)

The timeline is a great feature, I'm currently working on adding all this

of course, blog news

page updates

FAQ entries

comments on pages

 

The result is not yet perfect, but it's working quite nicely, using different 
bullets colors depending on type of item. I still have a problem in Jeremi's 
part (XML generation), because it seems that most recent entry in RSS is not 
taken into account in generated XML, and I really don't understand why (it's a 
for $entry in $entries with xwiki.feed.getFeeds(url), it should retrieve 
everything !?)

 

Also, when your timeline is "rich" it's quite unreadable, because newer things 
go too far in the bottom and don't display at all. I'm trying to make the 
timeline automatically "magnify" itselfs for current period of time (+- n 
hours), so items will be able to show up side-by-side, but I'm still failing to 
do it. 

 

The timeplot also seems very cool ;-) Only problem (for both timeline & 
timeplot) is that if it's rich it can take long to show up ... But it's a very 
nice and synthetic display.

Hi,

I've been trying to understand why the  trick is needed. Just to help 
to follow this issue... http://simile.mit.edu/issues/browse/TIMELINE-24

But I am still far from being able to contribute with an useful page about the 
use Timeline within XWiki. I am not even able to feed a sample Timeline with 
any thing different than the Jeremi's example at 
http://www.jeremi.info/index.php/feed/rss2!

Please, Jeremi, could you provide some example about how to feed the timeline 
simply with xwiki blog news?

Thank you so much,

Ricardo

Hi Guillaume,


I think that to have timeline working here will be of major
interest for our group. So, let me try to generalize its usefulness. I
think that the reference given by Jeremi in the original entry
(http://www.jeremi.info/index.php/post/2006/11/28/Simile-Timeline) plus
the  trick in his second message solve the issue. If Jeremie
agrees, I will try to understand the whole thing and create ASAP an ad
hoc page.

 

> Great, I'm sure both Jeremi and Jeremie will be ok (I'm seeing Jeremi
on Wednesday, I'll check with him just in case)

 

Has any of you tested Simile Timeline's sister project Timeplot (
http://simile.mit.edu/timeplot/  ) ? 

Apparently it uses the same xml format for its data files, I thought it
might be used to generate statistics from a wiki use by turning a XWiki
Instance own RSS feed into the RSS plugin, creating the XML and
displaying the timeplot. Actually, I might try and do it as well :-)

Re: [xwiki-users] XWiki scripting for end user (not Groovy)

[BOUSQUET Jeremie]

Hello *,

 

I quite agree with all that's been said in this topic about usability. I
must say also as old 0.9 versions user, that usability,
user-friendliness, have been considerably improved since these old
versions, thanks to xwiki great team ;-) So I believe this will continue
to evolve and be better and better with new releases.

 

About scripting : in my team we had "basic" end-users (not quite
participative to start with), and 2 admins (including me). As admins we
added much dynamic features in many pages, scripting, groovy, HTML, SQL
requests and so on ... Now end-users are much more participative, and
problem is that :

- we broke possibility of using WYSIWYG editor on these highly
dynamic pages

- for end-users, editing these kind of pages is an awful
experience, because it's not human-readable anymore (accepting
developers are not completely human ;) ).

In my opinion with XWiki architecture it should be strongly advised to
separate "pure content" pages and dynamic or complex pages, using macros
for example. It's a good development practice anyway, but you might not
think about it when you start working on a wiki site.

 

Anyway I don't regret using XWiki because it's a great wiki IMO, and I
really appreciate the way it evolves

Re: [xwiki-users] [ANN] XWiki Enterprise 1.2M2 Released

[BOUSQUET Jeremie]

Yes I talk about the .exe uninstall feature, it removes the complete directory 
only if you check "Force suppression of [install_dir]\XWiki Enterprise".

I left it unchecked first time, and after reinstall found xwiki-core 1.1 jar 
mixed with 1.2 jars in lib subdirectory, so I believe it did not suppress 
everything in this case ...

I had 1.2.M1 or 1.1.RC2 installed previously (I'm afraid I didn't note which 
one ...)

Go grab it at http://www.xwiki.org/xwiki/bin/view/Main/Download

This is the last milestone release for the 1.2 version. It's

and will focus on improving the stability. The roadmap is to release 1.2 final 
for beginning of December 2007.

 

Main changes from 1.2M1:

* Completely redesigned the UI for managing permissions and 
groups/users. It's now a nice Ajax interface which scales to any number of 
users.

* A new Mail Sender plugin has been added. It's a generic 
plugin that you can use from Velocity/Groovy pages and that is also used by the 
Watchlist feature below to send notification emails.

* New Watchlist feature which allows watching pages and spaces 
and receive email notifications when they are modified.

Re: [xwiki-users] Import of Backups

[BOUSQUET Jeremie]

Hello,

I can give you just a feedback on export/import operations on large
wiki, because I did it once.

2 remarks (that may help you or not, I'm afraid) :
- for large wikis, I preferred to split my .xar in smaller xars, by
space for example, editing the file containing the list of documents in
each .xar (even if it didn't seem mandatory for me, at least in older
versions of xwiki). It was useful because for large .xar attachments, it
can become VERY painful ...
- you should also check your export before importing. XWiki does not
complain much on export, and almost always it will succeed. But if you
unzip your .xar and have a look inside it, you might see that some pages
failed to be exported, and size of files is 0Kb. To import, you need at
least to delete these empty files. I didn't analyze why export failed
for these pages, so I migrated what I could with .xar, and performed
copy/paste for the others.

These remarks are valid for wiki 0.9 migrated to 1.0, I did not test
massive export/import on last versions.

Jeremie

that big, yet
the tomcat process consumes about 1Gb resident memory (2Gb in total) 
while attaching
which leads to massive swapping and slowdown. I wonder what will happen,
if
a wiki is really heavily populated with lots of attachements?

After the xar is attached, I cannot select it, because an exception
occurs:

Wrapped Exception: Error number 2002 in 2: Error parsing xml
Wrapped Exception: Error on line 346 of document  : Character reference 
"" is an invalid XML character. Nested exception: Character reference

"" is an invalid XML character.

Any hints about how to do the migration?

Re: [xwiki-users] Error because of Preferences

Hi,

There are good chances that you did not lost any data, unless you erased
your database, but you would have noticed ... ;-)

I had the same problem after migration of wiki kernel version. When
re-deployed the .war file in my tomcat container, I forgot to add again
the mysql*.jar library in $TOMCAT_HOME/webapps/xwiki/WEB-INF/lib

Or is there a possibility that your hibernate.cfg.xml file was updated
by someone else, or by you a long ago, and tomcat was restarted only
recently, so the problem appears only now ? Most of the time default
mysql user for xwiki is named xwiki ...

[xwiki-users] [1.1] Linking lists

[BOUSQUET Jeremie]

Hello,

 

I would like to do the following : create a new class, with a number of 
properties being lists.

For the end-user it would be like this : select an entry in first list, 
depending on the value, the second list is restricted to a limited number of 
choices. And the same on and on with third list.

Constraint : I cannot modify database and create new tables and such.

 

Do you think this would be feasible ? I hoped, if yes, someone could just 
through some ideas to start with, because I'm not sure on how to proceed to 
have such "dynamic" lists ...

 

Thanks,

 

Jérémie

Re: [xwiki-users] [1.1] "With history" import option

[BOUSQUET Jeremie]

Ok,

 

Thanks Vincent, the best was to test it ! :-) (and it's what you said)

 

So :

-  without "with history" option selected : local page history is 
overwritten, new page version is imported page current version (for example 
"1.16", but without previous versions)

-  with "with history" option selected : local page history is 
overwritten, new page version is "1.1"

 

To facilitate migrations, I think the ideal option would be "add imported page 
version on top of local page version", just as if importing an existing page 
would be a modification of this page.

This way, it would be possible very easily to:

-  compare page before and after .xar import

-  rollback a page to previous state (without having to reimport a 
previously exported .xar on top of it ...)

 

What do you think ?

 

BR

Jeremie

Does it mean :

No



-  history of imported pages will be preserved and replace local pages 
history

 

Yes



-  history of imported pages will be preserved as well as local pages 
history (concatenation)

No

 

At least that's what I understand (haven't checked it). 

 

Ludovic, can you confirm?

 I added a line for this in the admin guide, but need to detail the 
exact way it works (btw I need to be sure of how it works before importing 
pages in my own wiki ;-) )

Subject: [xwiki-users] [1.1] Velocity, summing properties

Hello,

 

I would like to perform a sum in a velocity script.

The following works well:

#set ($a = 1)

#set ($b = 1)

#set ($c= $a + $b)

 

$c returns 2

 

But if I modify with

#set ($b = 
$categoryDoc.getObject("Blog.Categories","name",$bcategory).get("color_red"))

 

... the sum does not work anymore. It seems that $b is considered as a string 
and gets appended to $a instead of added. The property retrieved "color_red" is 
of type Number.

 

Is there a way to convert it in order to perform arithmetics on it ? I looked 
at velocity dev guide but I'm quite confused ...

 

Thanks,

Re: [xwiki-users] [Announcement] XWiki Platform and XWiki Enterprise1.1 Release Candidate 1 released

[BOUSQUET Jeremie]

Hi,

Thanks for this release and all your great work on XWiki !

Maybe I'm too fast but I think the .war distribution for 1.1.RC1 is missing on 
the download page (invalid file id in forge)

Subject: [xwiki-users] [Announcement] XWiki Platform and XWiki Enterprise1.1 
Release Candidate 1 released

Hi,

This is first release candidate for the final 1.1 release. It brings
only several bug fixes and improvements, as the 1.1 release is almost
ready. It was delayed a bit by unexpected bugs introduced by some
fixes, but we managed to get it along. Unfortunately, there will have
to be another release candidate, as right after finishing the release
we detected several things that could be improved, and we're also
trying to make the installer a bit more user-friendly.

See the release notes (
http://www.xwiki.org/xwiki/bin/view/Main/ReleaseNotesXWikiEnterprise11RC1
) for more details on this release. With release candidates we need
your help more than ever for testing and reporting any remaining bug
(and eventually provide a patch, too).

Thanks!
