[xwiki-users] Special characters in pagename (URL)
by Hamster 08 Feb '13

08 Feb '13

To all, My users are driving me crazy...allthough I have stated several times that they must NOT use any special characters in the pagename (URL), they still create pages with special characters. I also don't like any spaces in the URL (which are replaced by a "+")... Is there a way to parse the pagename before it's created and remove any special characters? -- View this message in context: http://xwiki.475771.n2.nabble.com/Special-characters-in-pagename-URL-tp7582… Sent from the XWiki- Users mailing list archive at Nabble.com.

[xwiki-users] [myxwiki] new wiki request
by xrichard 08 Feb '13

08 Feb '13

Hello, I had a dream ;-) to share my personnal notes and geek tips through a wiki rather than on text files stored on my hard drive. I started to write tutorials on a cloud wiki(1) but I discovered that cloud wiki does not allow guest comments and runs an old version of xwiki(2). I have discovered later that it's possible to run a full wiki if we gently ask on this mailing list. Please find below my wiki request. - My xwiki.org's user name: xrichard - Description of the Wiki: first level tutorials on Windows, Android, Ubuntu and maybe more - Server Name for this new wiki: tutos I hope a kind admin will create this wiki for me on the "XWiki Community farm". Thanks in advance ;-). Notes: 1. my test Wiki (sorry it's in french): http://tuto.cloud.xwiki.com 2. limitations on cloud xwiki, see discussion here: http://xwiki.475771.n2.nabble.com/Guest-access-on-wiki-hosted-on-cloud-xwik… -- View this message in context: http://xwiki.475771.n2.nabble.com/myxwiki-new-wiki-request-tp7583032.html Sent from the XWiki- Users mailing list archive at Nabble.com.

[xwiki-users] EventListener automatic start - is it possible?
by Eugen Colesnicov 08 Feb '13

08 Feb '13

In the XWiki existing great technology - custom EventListeners, which can execute, for example, on 'save page' event some script. Existing some nice examples of using this technology: http://extensions.xwiki.org/xwiki/bin/view/Extension/Title+Post+Processing+… http://extensions.xwiki.org/xwiki/bin/view/Extension/Create+Object+with+Con… But, in the past, problem was, that your EventListeners cannot automatically start (for example if application server restarted). I know right now only one 'trick' - right a scheduler job, which every 5 minutes restarts EventListener. Here - http://platform.xwiki.org/xwiki/bin/view/DevGuide/GroovyNotificationTutorial existing example of such job, but: 1) this is like a 'trick' - not a normal solution 2) existing troubles of writing such jobs for not qualified users (like me :) ) My question - at this moment, at the end of 4.x cycle, existing more comfortable solution of this problem? If not - do you have (this is question for developers) plans for the future to give for the users some instrument which can do it easy? -- Thanks beforehand!

[xwiki-users] XWiki 4.3 will not maintain logged in status of users
by Lineberry, Casey 05 Feb '13

05 Feb '13

I apologize if this issue is somewhere out in this user list, the web or on xwiki.org docs, but I am unable to find anything out there on it. We're using XWIki 4.3-rc-1 running under Tomcat 7.0.32 on Red Hat 5.7 64-bit. Everything was working fine. Then, all of a sudden, all users are prompted to login after every click. It's now impossible to import or export any content. Editing is impossible. In the catalina.out from tomcat, we see the following over and over again: 2013-01-28 14:11:04,531 [https://epswiki.sdc.vzwcorp.com/xwiki/bin/login/XWiki/XWikiLogin?srid=BOeR3…] DEBUG o.x.c.ExecutionContext - Getting undefined property localization.bundles from execution context. 2013-01-28 14:11:04,534 [https://epswiki.sdc.vzwcorp.com/xwiki/bin/login/XWiki/XWikiLogin?srid=BOeR3…] DEBUG .s.DefaultScriptServiceManager - Failed to lookup script service for role hint [workspace] org.xwiki.component.manager.ComponentLookupException: Can't find descriptor for the component [role = [interface org.xwiki.script.service.ScriptService] hint = [workspace]] at org.xwiki.component.embed.EmbeddableComponentManager.getComponentInstance(EmbeddableComponentManager.java:355) ~[xwiki-commons-legacy-component-default-4.3-rc-1.jar:na] I am unable to find anything that can point me to where our configuration has gotten hosed. We are configured to use LDAP authentication against an MS Active Directory domain. As stated earlier - that has been working fine - and this just started happening. Any direction in how we can get this corrected would be greatly appreciated. Thanks, Casey

[xwiki-users] Grant only View Rights to a specific user
by Hamster 05 Feb '13

05 Feb '13

Hi all, We are using LDAP and I want to grant a specific user ONLY view-rights (on the entire wiki) As far as I can see, I can't just grant him "view-only" rights to the wiki, because the space-rights will grant the user edit rights (the user is also in the XWikiAllUsers group). Do I need to apply "view-only" rights for that specific user on every space in the wiki? If that's the case, how do I handle the fact when an "admin"-user creates a new space? (where the specific user should have "view-only" rights by default?) That's kind of dangerous, don't you think? Or am I missing something? -- View this message in context: http://xwiki.475771.n2.nabble.com/Grant-only-View-Rights-to-a-specific-user… Sent from the XWiki- Users mailing list archive at Nabble.com.

Hi Everyone, I was just trying to upgrade from 3.0.1 to 4.4. as I figured I can't save XWikiPreferences anymore: 13:07:17,307 [http://0x64plusxwiki.local.0x64plus.de:8080/xwiki/bin/saveandcontinue/XWiki…] [http://0x64plusxwiki.local.0x64plus.de:8080/xwiki/bin/save/XWiki/XWikiPrefe…] ERROR .AbstractFlushingEventListener - Could not synchronize database state with session org.hibernate.StaleObjectStateException: Row was updated or deleted by another transaction (or unsaved-value mapping was incorrect): [com.xpn.xwiki.objects.IntegerProperty#<?xml version="1.0" encoding="UTF-8"?> <showcomments></showcomments> ] at org.hibernate.persister.entity.AbstractEntityPersister.check(AbstractEntityPersister.java:1769) … Is there any way to fix this? Or force the save of my current XWikiPreferences? Thanks in advance, Florian

[xwiki-users] Search Suggest Issues

Good Afternoon All, I am currently having issues with the search suggest feature of Xwiki, the problem I am having is that links to attachments are showing in the "document content" part of the drop down of this feature which I need to be excluded. I have disabled Attachment name and Attachment Content from from SearchSuggestConfig and even tried excluded attachments by using "__INPUT__* NOT type:attachment" & "__INPUT__* NOT .doc" from document content.

[xwiki-users] too many open files with Lucene
by CHENEAU-GREHALLE Nicolas 31 Jan '13

31 Jan '13

Hello, Since the migration from 4.1.3 to 4.4, there are "too many open files" alerts in Tomcat (release 5.5). I changed limit from 1024 (default value) to 4096 but the problem is not solved. It seems there are many open files used by lucene : Total tomcat open files : >/usr/sbin/lsof |grep java | wc -l 3318 Lucene open files : >/usr/sbin/lsof |grep java | grep "/xem/data" | wc -l 2524 Lucene "deleted" open files : >/usr/sbin/lsof |grep java | grep "/xem/data" | grep deleted | wc -l 1663 This behavior is new with 4.4. There is a known problem with Lucene ? Thank you Ncg
