[xwiki-users] Impossible to create users and groups in a slave wiki of XEM 2.4
by Maxime Mathieu 20 Sep '10

20 Sep '10

Hi, Just done a fresh install of XEM2.4 and I encounter the following problem. In the templatexe wiki, it's impossible to add a new group or a new user (the Add button do nothing). If I edit the objects of an existing group (XWikiAllGroup for example), a warning is displayed : "Some objects from this document contain deprecated properties which were deleted from their respective classes." In fact, I detected that the *XWikiGroups and XWikiUsers classes are not defined* (they do not exist) in this templatexe wiki. In the main wiki, all is ok (and the XWikiGroups and Users classes are well defined). Nothing in the xwiki.log. Do you have any idea to help me ? Best regards, Maxime Mathieu

[xwiki-users] XWiki users visibility
by Andrea Belli 20 Sep '10

20 Sep '10

Hi all, I missed something about XWiki users object visibility. I put in a wiki page the velocity script for implementing the Live table sample with XWikiUser objects. It works if I log in with Admin rights. If I log in with a user without Admin rights (Programming rights are ok) the live table shows no elements. Thank you a lot, Andrea

[xwiki-users] Bad HQL queries
by Flavius Olaru 18 Sep '10

18 Sep '10

Hi, I've done a installation on my localhost (Windows XP machine) of XE 2.1.1, Tomcat 6 and MySQL 5.1. After this i wrote a bad hql query and executed it which brought MySQL to spyke the CPU usage to 100% and even more rendering both the localhost and database unusable. {{velocity}} #set($badhql = ", BaseObject obj, StringProperty stringprop, LargeStringProperty largestringprop where (doc.name like '%$text%' or doc.content like '%$text%') or (obj.name=doc.fullName and stringprop.id.id=obj.id and stringprop.value like '%$text%') or (obj.name=doc.fullName and largestringprop.id.id=obj.id and largestringprop.value like '%$text%')") #set($ok = $list.addAll(0, $xwiki.searchDocuments("$badhql"))) {{include document="XWiki.Results"/}} {{/velocity}} The bad thing is that $xwiki.searchDocuments brought me to this state (no programming rights.). Now my question is: Are there any remedies against this? MySQL configuration statements that prevent this kind of behaviour? -- Flavius Olaru

[xwiki-users] nested types
by travis＠archive.org 18 Sep '10

18 Sep '10

Hi XWiki people, I need a "semantic" way to edit xml data. This is a project that could consume a very large portion of my future time, but in the near term I'm looking for a way to get this typed data into a wiki format so that the object graph can be clicked through and offsite links can be managed. First, I need to be able to have nested types. That is, a class has a field, the type for which is a class I have defined elsewhere. I don't see a way to do this in XWiki. Am I missing something? Seems like a typing system is incomplete without being able to have classes have attributes of defined types. Travis

[xwiki-users] edit fails with xwiki/tomcat proxy from nginx
by linuskamb 17 Sep '10

17 Sep '10

Hello, All. I am trying to set up an xwiki/tomcat(5) installation that is proxied behind nginx (httpd). I was working with 2.4, but I am currently trying 2.5 snapshot 20100917.044441-172. I've got it all working internally, the the proxies and xwiki redirects work externally. But when I try to edit a page, I get 2 javascript errors : (I got 3 errors with 2.4) Z is undefined in prototype.js : 1877 and Permission denied for <external host> to get property Window.document from <internal host:port> at http://<external host>/xwiki/resources/js/xwiki/wysiwyg/xwe/2ED0D1BCD0DB002FD3C0404AF6E0AAA3.cache.html Don't know if this is nginx configuration or xwiki issue. If anyone has been successful running behind nginx I would love to hear any tips. I'm rather new to both. thanks a lot, Linus -- View this message in context: http://xwiki.475771.n2.nabble.com/edit-fails-with-xwiki-tomcat-proxy-from-n… Sent from the XWiki- Users mailing list archive at Nabble.com.

[xwiki-users] Migrating Xwiki
by Kaya Saman 17 Sep '10

17 Sep '10

Hi, I'm wondering if it's possible to migrate Xwiki from one system to another?? I currently run Xwiki on a FreeBSD 8.0 RELEASE x64 platform with 4GB RAM in a dedicated FreeBSD Jail, however I'm having an issue with Java spinning up the CPU to 100% rendering Xwiki inoperable! If I migrate it would be from FreeBSD to either a dedicated FreeBSD system or an OpenSolaris based system on Nexenta. Currently I run Tomcat6 coupled with Postgresql, but would migrate to Glassfish and MySQL. Is it just a matter of backup the Xwiki from the web GUI then restore under Glassfish and convert database from Postgresql to MySQL then attach at other end? Or can I just simply dump the /webapps/xwiki folder into Glassfish or another instance of Tomcat? Thanks for any advice!! Regards, Kaya

[xwiki-users] Table styles
by adoro 15 Sep '10

15 Sep '10

Hello community, how can I create tables that would have different background colours for odd and even table rows with the new WYSIWYG (like it was in old vers.1.0 Syntax .wiki-table?). Or is there the appropriate macro?

[xwiki-users] SpaceExplorer (treeview) in xWiki Enterprise 2.4
by Zuzana Zapletalova 15 Sep '10

15 Sep '10

Hello, I upgrade my xWiki to 2.4 and I have a problem with SpaceExplorer. It doesn't work. When I try to use it, xWiki returns an error: XWIKIEXPLORER.JS DEPENDS ON XWIKI.JS In the older version of xWiki everything works fine (2.2). I was going through the js scripts and the structure is the same as it was in xWiki 2.2. Does anybody know where is the problem? Thanks, Zuzana.

[xwiki-users] XWiki SQL Plugin
by afra 15 Sep '10

15 Sep '10

Hi @all, did one of you guys get the SQL-Plugin to work with 2.4? I did everything the installation instructions said to do. Even made a sample jsp page which worked just fine with querying the database and displaying my table. But usage of the plugin in any xwiki page doesn't work. Even when using such stupid query as select '1' as 1, '2' as 2 there does not seem to be any resultset returned which i could display via velocity script. Is there any trick i don't know or is the plugin simply broken? Thx -- View this message in context: http://xwiki.475771.n2.nabble.com/XWiki-SQL-Plugin-tp5530893p5530893.html Sent from the XWiki- Users mailing list archive at Nabble.com.
