[xwiki-users] CSS customization and themes
by Andreas Hahn 23 Mar '11

23 Mar '11

Hi again, in my ongoing efforts in customizing the appearance of the pages of my wiki I've followed the steps of the skin extension tutorial: http://platform.xwiki.org/xwiki/bin/view/DevGuide/SkinExtensionsTutorial I've created a StyleSheetExtension and selected 'Use this extension' 'Always on the wiki' and it works as expected. However I've started to replace fix color settings by references to the themes settings e.g. $theme.borderColor ... $theme.titleColor and also I've checked 'Parse content' 'Yes' and disabled caching this doesn't work. Velocity statements seem not to be processed or I am referring to invalid property names. (I have been trying the ones from /templates/colorThemeInit.vm) What am I doing wrong here ? In the example the page is laoded on demand with $xwiki.jsx.use("XWiki.MyFirstStylesheetExtension") so I would assume there should be a document named "MyFirstStylesheetExtension" in XWiki space (or maybe some other space). Thats not the case for my own instance of XWiki.MyFirstStylesheetExtension that I've added. Shouldn't I be able to find the instance as a document somewhere in the spaces ? Thanks for your support Andreas

[xwiki-users] XWiki going out of resources
by Andreas Hahn 23 Mar '11

23 Mar '11

Hi XWiki users, fwiw I just want to share my experiences and observations with XWiki instance running out of memory. I was having a hard time to track this down but in the end I could successfully isolate the problem. For quite some time my XWiki instance was getting unresponsive to requests sooner or later. The Wiki was hosted on a VirtualBox VM and in most cases the VM guest was just freezing and needed to be restarted leaving no usable traces in the logs. In some cases I even found JVM crash reports so I first checked different JVMs and VirtualBox versions (PUEL and OSE licences). I had no success with this approach and so I moved the XWiki directly to a host environment (Ubuntu 10.10). I added Server instrumentation (VisualVM) but still the wiki got down after a while. Surprisingly the system was hanging although in many cases there was even enough memory available (I checked different VM settings up to 4GB). Finally a VisualVM thread dump showed what happened: When the robots came visiting my service they query a large number of pages and among them was one user-url: .../XWiki/someUser which ran into an infinite looping condition when rendering the page. I don't know how this could happen but as a result the whole memory was consumed and partly released afterwards so it seemed that there is still enough space available. Once this happened however the Webserver needed to be restarted because it wasn't responsive any more. Since I have deleted this user account everything is running ok for a couple of days now - I still have to move the service back into the VirtualBox guest VM. What puzzles me finally that its possible that one single request can kill the service by going into an infinte rendering loop. I would have thought that at some level there is a depth limit to prevent such conditions. Hope these observations help someone though .... enjoy Andreas

[xwiki-users] XE 2.7.1 Office Preview nor Macro NOT Working
by Ramon Gomes Brandão - SERINT 22 Mar '11

22 Mar '11

Hi, I've could get my upgrade from 2.4.3 to 2.7.1 working in my test environment. The new features seem remarkable indeed, but one of the most important for our XWiki instance is not working properly: the Office Preview in attachments of Office Macro. The little eye right beside the edit and delete buttons on the attachments sections doesn't appear. Is there something I'm missing? Any configuration steps required? If I try the office macro, I get an exception: "org.xwiki.rendering.macro.MacroExecutionException: Failed to view office attachment. " and "Caused by: java.lang.Exception: Attachment [name = [DescricaoSGAeSGA1.doc], type = [ATTACHMENT], parent = [name = [WebHome], type = [DOCUMENT], parent = [name = [Main], type = [SPACE], parent = [name = [xwiki], type = [WIKI], parent = [null]]]]] does not exist.", but the attachment is really there, showed in the attachments section. How can I handle this? Ramon Gomes Brandão

Hi xwiki users, I am a bit worried I have messing up all the things with my xwiki..

Could you please help me? I didn't found any specific information about it online. Do I need to install again the xwiki?? Did I lose my work???

[xwiki-users] Drop mailing lists in favor of a forum software
by Andreas Hahn 22 Mar '11

22 Mar '11

Hi everyone, I'd like to make the proposal to drop the existing mailing lists in favor of a forum (bulletin board) software. The objective is to promote the XWiki community discussions to a broader audience. 1) A forum serves like an advertising window as anyone can read the contributions without subscription. 2) Anyone can judge the activity by reading the view count. 3) New users can get in touch with the community without being urged to subscribe to a mailing list. 4) Many people consider mailing lists as spam and prefer not to subscribe 5) Contributions have a longer visibility and older entries will get responses 6) Communication gets more efficient as the same topics won't get repeatedly discussed 7) To my experience forums get much better indexed by google as mail collectors like Nabble , Markmail, e.t.c. 8) Forums encourage user to user discussions and you will see new users taking an active role 9) There should be at least one additional category IMHO: administrators 10) A forum is more pleasure to read once a topic split into many threads 11) A forum is beneficial when expecting increasing support requirements - some real large scale forums were run by just a few moderators 12) More people will see what a teriffic job the XWiki team does. Here's my +1 Andreas

[xwiki-users] Remapping Meta+G Shortcut
by phancox 21 Mar '11

21 Mar '11

Is it possible to remap the Meta+G (Ctrl+G in Windows) to another key? Just switched from Firefox to Chrome and Chrome captures Ctrl+G for searching. Also noticed that the default Welcome page in XWiki 2.7 has minor layout problems when displayed in Chrome. The Xwiki.org Playground (version 2.6.2) appears to be OK. Anyone else seen this. e.g., the spaces column drops the text to the right of the icon onto the line below. -- View this message in context: http://xwiki.475771.n2.nabble.com/Remapping-Meta-G-Shortcut-tp6183603p61836… Sent from the XWiki- Users mailing list archive at Nabble.com.
