Hi, We got a new load of spam related hammering on xwiki.com. It is more and more horrible and creates more and more unuseful load on xwiki.com. Spam robots have included creation of XWiki accounts and use of these accounts to publish spam data in the wiki pages. I've had to deactivate statistics since each spam-related request that cannot be catched by mod_security creates load on the database for these statistics. The only way to get statistics back will be to use Javascripts which triggers a statistics storage request in the database (which would be ignored by spam robots and search engines), or to wait until we can read Google Analytics or another external statistics engine and redisplay it on xwiki.com. In the future we will propose a tutorial to activate Google Analytics on your wikis. If you know how to do it you should include this on your wiki pages to get statistics for your wiki. I'm getting more and more worried about these spam robots and would welcome any help and ideas on how to handle this to make xwiki.com a viable platform for hosted public wikis.

[xwiki-users] Sort error in tags

by I.T. van den Dobbelsteen-Heemskerk

Recently I included the tagcloud snippet in one of my panels. In some pages it works fine, but in other pages I get this error message in stead of the cloud: Error number 4001 in 4: Error while parsing velocity page Main.Tags Wrapped Exception: Invocation of method 'sort' in class com.xpn.xwiki.api.XWiki threw exception java.lang.NullPointerException @ Main.Tags3,25?

Panels off

by Gunter Leeb

Hi, Is there a simple way to turn the panels off for a particular page? I know this is possible, by creating the page in a new space and configuring the new space not to show the panels.

[xwiki-users] Cannot translate page in xwiki-1.1.1

by Steffen.Balzer＠it-informatik.de

Hi all, while testing the translation feature with the new xwiki-1.1.1.5166 release I bumped into the following problem: Xwiki saves the translation of a page in the default language, regardless of the language I have selected to translate to in edit mode. As a consequence the default translation has been overwritten and no additional translation has been shown in the top-right info panel. For the test environment I've imported the xwiki-enterpise-1.1.1.xar into a naked standalone xwiki installation an configured it with three languages (de, en, fr) and de as default language on the global preferences page. I use the firefox2 as browser. Her are the detailed steps to reproduce ths problem: (1) Create new page (2) Edit this page in the default laguage and save&view it (3) press "Edit"again an select a different langauage in the translation panel => The panel shows that the translation of the selected language is now beeing edited (4) Translate the page and save&view it => no additional translation shows up and the default translation has been overwritten. Am I missing here something or is this a bug? Thanks a lot for helping me out on this. Steffen

[xwiki-users] Shifting to a new computer

by V. Harikrishnan Nair

Hi. I am shifting my wiki into another computer. I wish to retain the same state of the wiki as it is now - the same registered users, document pages, preferences etc. Could I just copy-paste the wiki files ? :) Harikrishnan -- View this message in context: http://www.nabble.com/Shifting-to-a-new-computer-tf4676458.html#a13361084 Sent from the XWiki- Users mailing list archive at Nabble.com.

[xwiki-users] Adding a document in XWiki.org

by V. Harikrishnan Nair

Hello... I've been able to read and enter data into my personal MySQL database (after a very long night, finally!) and I think this should be added into the documentation for XWiki.org but first, I want to get data from a textbox into the database... Because the first thing that newbies like me wanted to do was to communicate with a personal database (especially through the use of forms), I believe this is important. How can I add a document in XWiki.org ? Do I have editing rights ?

[xwiki-users] Parsing textbox data

by V. Harikrishnan Nair

Hello again ! I want to take a string entered into a textbox and place it into a MySQL db (which is not XWiki's RDB). For that I created a simple form shown below - <form action = "VelocityTest2" method = "get" > <input type = "text" name = "formval"> <input type = "submit" value = "submit"> </form> This is the velocity page (named VelocityTest2) which is supposed to parse the string entered into the text box - #set($groovyObject = $xwiki.parseGroovyFromPage("Amrita IIS.GroovyTest4")) #set($j = $Request.getParameterValues('formval')) $groovyObject.SQL_conn($j) A Groovy page (named GroovyTest4) takes that string and enters it into the MySQL db with the SQL_conn() function and I'm positive that my groovy code works. My problem is that the string is not being parsed from the textbox into the Velocity page. I am getting a null value instead. Thanks, Harikrishnan -- View this message in context: http://www.nabble.com/Parsing-textbox-data-tf4724953.html#a13508865 Sent from the XWiki- Users mailing list archive at Nabble.com.

[xwiki-users] How do I get the rendered content of another instance of the same class?

by Andreas

Hello, First of all, to all developers, congratulations to Xwiki! It is by far the best piece of software I've seen in a while. The introduction to "what is it?", "what can it do?" and the install and running process were just fantastic. Right now I'm entering the stage where I want to write my own application using Velocity, and I'm realizing that there is one or two orders of magnitude to little Xwiki documentation around, and existing documentation is often faulty or outdated. Instead, I'll try to ask my questions in this place. Question: I have two instances (InstanceA, InstanceB) of class HowTo, and I want to display the rendered content of InstanceB in InstanceA in a info box. The class/instances have been generated analogously to the FAQapplication tutorial. If I do InstanceB.getRenderedContent(), it will return the rendered content of InstanceA, not InstanceB. Assuming I need to set the $doc context, I tried to include in InstanceA: #set ($doc = $xwiki.getDocument("Space.InstanceB")) #info($doc.getRenderedContent()) and would hope the InstanceB context would be used for rendering $doc. But instead it cyclically and repeatedly renders InstanceA in itself, until the engine refuses to render more levels. I've also tried $xwiki.renderText and giving it unrendered InstanceB text and the InstanceB document as arguments, but get the same effect. Some more details: I work as Admin, so have programming rights. I have also tried $context.setDoc($xwiki.getDocument("Space.InstanceB")), which seems to have no effect, and also #info($doc.getContent()), which returns the raw class template (which, by the way) uses includeForm(...)) Any ideas? Thanks, Andreas

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi! In the past days I sucessfully upgraded our XWiki installation from 0.9.840 to 1.1.1. We use jboss-4.2.1.GA and postgresql-8.2.5 and everything went quite well! In the process I only had to remove the servlet-api-2.3.jar from WEB-INF/lib/ as it is incompatible with the one JBoss AS already has. I also added lucene-analyzers-2.0.0.jar as I want to use Lucene's german analyzer. Porting the database for use with XWiki-1.1.1 also went well using the "schema_pre.sql" and "schema_post.sql" scripts Rudolf Van der Leeden posted to this list a few months ago (many thanks, Rudolf!) We now have our wiki with about 2000 pages on version 1.1.1 and are very happy with the results. XWiki-1.1.1 is really amazing and the improvements relative to 0.9.840 are great! Excellent work! There is one thing I still haven't solved, though: The application seems to work fine, but in the logfiles I find lots of the following messages: [...] 19:38:15,510 INFO [STDOUT] 19:38:15,504 ERROR http-0.0.0.0-8080-2 http://test5.intern.xss.co.at:8080/xwiki/bin/view/Main/ SimpleLog4JLogSystem:logVelocityMessage:154 - Left side ($first) of '==' operation has null value.
