Hello Everyone- I have two basic requests that I need help on. I have installed xwiki (war file) on Jboss app server and made LDAP authentication for editing purposes. (1) How can I add additional layer of security for certain pages only for a specific LDAP sub-group (security group). (2) What do I need to do to have the capability of importing MS Office documents directly into Xwiki. It is error out stating Open Office Plug-in server is not running. I do have Open Office installed and updated the config file. Greatly appreciate the help!

[xwiki-users] Problem with document history
by Guillaume Delhumeau 18 Jan '12

18 Jan '12

Let me explain you. 1) We have a "MyTests.TestClass" class which contains a unique field "date" of type "date". 2) The current document have a single object of type "MyTests.TestClass". You can set whatever you want for the value of the field "date". 3) The current document code is: {{velocity}} = History = #set($revs = $doc.getRecentRevisions(10)) #foreach($rev in $revs) #set($oldDoc = $doc.getDocumentRevision($rev)) #set($prop = $oldDoc.getObject('MyTests.TestClass').getProperty('date').getValue()) == Rev : $rev == * Class: $prop.class.name * Value : $prop #end = End History = {{/velocity}} 4) Do some edit in order to have something to display in the history 5) Here are my results: History Rev : 17.1 Class: java.sql.Timestamp Value : 2012-12-10 00:00:00.0 Rev : 16.1 Class: java.util.Date Value : Mon Dec 10 00:00:00 CET 2012 Rev : 15.1 Class: java.util.Date Value : Mon Dec 10 00:00:00 CET 2012 6) The problem is that the field "date" is a java.sql.Timestamp for the current version but then become a java.util.Date. Is it normal ?

Turns out all my wiki problems with disappeared attachment, scripts not running, etc were down to partition /var running out of disk space! So moved default locations of apache tomcat and mysql to a much bigger partition using symbolic links to link to the new locations and now all seems well. Should have checked the obvious (disk space) first! So if anyone else gets strange behaviour with xwiki - check your disk space first and save yourself a lot of time and hassle chasing down these 'problems'! -----Original Message----- From: users-bounces(a)xwiki.org [mailto:users-bounces@xwiki.org] On Behalf Of goldring, richard Sent: 16 January 2012 08:18 To: 'XWiki Users' Subject: Re: [xwiki-users] Can't attach files to wiki Yes its strange, This has happened since migrating from version 2.7 to 3.2. The import of the wiki pages via Exported xar files seemed to work ok, and the attachments are listed at the bottom of the wiki pages, butwhen you cick on them to view the attachments the wiki displays aa error message that the "The attachment does not exist."

[xwiki-users] XWiki 3.1 - Panel Wizard causing 100% CPU Utilization in RedHat w/JBoss
by Chris Meyer 17 Jan '12

17 Jan '12

Hi All, I am having an odd issue with the panel wizard in my test and prod instances of XWiki. The users are trying to click on "Panel Wizard" via "Administer this Wiki" and the system spikes to 25% CPU but never yields results. Later, they try again, another 25% CPU and no results.... ultimately they keep trying until I start getting administrative alerts that the system is overwhelmed. To recover, I need to stop/start the application. However, that only allows the application to function until they do the same thing again. This is a critical task for them to add the necessary navigation to their wiki. Anyone had a similar experience? Any ideas on how to troubleshoot this further? Thanks, Chris

[xwiki-users] Multiple 'classes', one form.. best practice?
by Joris Dirks 17 Jan '12

17 Jan '12

Hi all, I am making a database where each page can have multiple 'levels' of data, each next level should be shown to the user only when a condition has been met, say: 1: general information - Question - Needs additional research: yes/no 2: additional research (only shown if applicable): - Researcher - Findings My initial idea was to use seperate classes and create a combined class sheet, like in the code below, but I suspect that will give difficulty for instance when creating overviews in a Livetable. Does anyone have experience in uses like this? Thanks for your ideas! Joris #set($class1 = $doc.getObject('Example.Class1').xWikiClass) #foreach($prop in $class1.properties) .. #end if($class1.properties.needsadditionalresearch=="yes") #set($class2 = $doc.getObject('Example.Class2').xWikiClass) #foreach($prop in $class1.properties) ..

[xwiki-users] Issues while importing previous working xwiki XAR file in to new installed XWIKI setup?
by mohit gupta 17 Jan '12

17 Jan '12

Hi all, I have xwiki setup done on machine A with custom setting like log changed, user, group and space rights settings .Also had space contents/attachment. Now i did the fresh installation of xwiki on new machine B..What i wanted was every setting,content, attachment i created on machine A xwiki database should be migrated to machine B xwiki database. ** *What i did for this is :-* 1) On machine A, as admin user navigated to export. It asked me package name and description. I entered the value in that and it created a A.xar file. 2)Now after xwiki installation i.e after extracting * xwiki-enterprise-web-3.3.war* inside tomcat on machine B, i navigated to import and imported A.xar file.Now i log in as admin user. *Actual Problem* Now i see the main space webhome page on machine B different from machine A main space webhome page.Like under space i see this error Unknown macro: spaces The "spaces" macro is not in the list of registered macros. Verify the spelling or contact your administrator. Same error is there for Tags.Also i do not the setting i did on default colour theme like i changed the logo. Though i can see all the previous user,group ,space rights and content. *Not getting what i am missing here?*
