I am starting up Xwiki 6.4.2 in JBoss EAP 6.3 (running jdk1.7.0_51_x64). During startup I get below stacktrace in the server.log. I grepped through all jar files in the WEB-INF/lib directory but cannot find a class by that name. Infact, sisu-guice-3.2.4-no_aop.jar contains the com.google.inject package, but only the subpackages binder, internal, matcher, name, spi and util. The "servlet" subpackage is absent but appears to be required. The application doesn't complain any further. It creates its database tables and I can launch the Distribution Wizard (though that gives me a different kind of issue as per my other mail). What can I do to make my Xwiki install happy? 2015-03-12 18:56:21,287 -0500 WARN [org.jboss.modules] (ServerService Thread Pool -- 61) Failed to define class

[xwiki-users] [ANN] First version of Extension Tweak released
by Thomas Mortagne 12 Mar '15

12 Mar '15

Hi xwikiers, I finally started an extension that I want to start since a very long time now: an extension where to put extensions related tricks that are either not polished enough or too dangerous to put in the standard Extension Manager UI. You can find it on http://extensions.xwiki.org/xwiki/bin/view/Extension/Extension+Tweak and you can installed it with Extension Manager of course ;) I tested it mostly on 6.4.2 but it's using APIs that are supposed to exist since 4.0. It does not contain much yet but I will put more things I have in mind when I have some time and don't hesitate to add scripts you made for your needs here and there. -- Thomas Mortagne

[xwiki-users] Cannot upgrade Enterprise UI Extension to 6.4.2
by Charlie Mann 11 Mar '15

I am using the Extension Updater to upgrade our XWiki instance from 6.3 to 6.4.2 Whenever I try to upgrade the 'XWiki Enterprise - UI - Main Wiki All' package, I get the following error: * An extension with feature [org.xwiki.platform:xwiki-platform-appwithinminutes-ui] is already installed on root namespace ([org.xwiki.platform:xwiki-platform-appwithinminutes-ui-6.3]) class org.xwiki.extension.InstallException: Failed to resolve extension at org.xwiki.extension.job.internal.AbstractInstallPlanJob.installExtension(Abs tractInstallPlanJob.java:770) at org.xwiki.extension.job.internal.AbstractInstallPlanJob.installExtension(Abs tractInstallPlanJob.java:393) at org.xwiki.extension.job.internal.AbstractInstallPlanJob.installExtension(Abs tractInstallPlanJob.java:290) at org.xwiki.extension.job.internal.AbstractInstallPlanJob.start(AbstractInstal lPlanJob.java:220) at org.xwiki.extension.job.internal.InstallPlanJob.runInternal(InstallPlanJob.j ava:88) at org.xwiki.job.internal.AbstractJob.runInContext(AbstractJob.java:209) at org.xwiki.job.internal.AbstractJob.run(AbstractJob.java:192) I have tried to upgrade from 6.3 to 6.4.1 first and then upgrade from 6.4.1 to 6.4.2, but I still get the same issue when going from 6.4.1 to 6.4.2. Going from 6.3 to 6.4.1 works fine. Are there any workarounds to get Enterprise UI package to upgrade, or will this be something that is fixed in next release? Thank you, Charlie

Seem to have vanished, is there as way to bring them back ? I'm loving the copy and paste from Excel to create a table, but I would love to see the cell borders, it makes it much easier when navigating a larger table. Cheers

Re: [xwiki-users] Performance Frustrations
by Mahomed Hussein 10 Mar '15

Hi Thanks for the responses. Page you mention below just loaded a blank page (I assume that's the intention). CPU jumped to about 80% for that one request. That being said, performance has been a bit better today for some reason. There are a couple of extra tweaks I did this morning were: 1. Limited the activity plugin on the dashboard to only show the last 10 changes with 2 changes. 2. Disabled the image for one of the user's avatar. I have been happily adding documents today and it has been fairly acceptable. But that's just one active user. We'll see how it behaves when it has 10 users on at the same time. I might come back with more questions.

If it's fast then it means some of the UI elements slow down the view mode. It may be a panel for instance.

[xwiki-users] Document tree macro including pages from other spaces
by Jamal 10 Mar '15

10 Mar '15

Hi, I have a wiki in which several spaces have pages with the same name, like so: Space 1 |_ MyPage Space 2 |_ MyPage I would like for the "MyPage" in each space to list its child documents. When I use the Document Tree macro for this, it lists the subpages of every page named MyPage, irrespective of what space it's in. This happens even when I specify the full "document:wiki:Space.Path" in the "root" setting. If I rename the pages as "MyPage - Space 1" and "MyPage - Space 2" for example, this doesn't happen. Is this the normal behavior when 2 or more spaces have pages with identical names? Thanks, J -- View this message in context: http://xwiki.475771.n2.nabble.com/Document-tree-macro-including-pages-from-… Sent from the XWiki- Users mailing list archive at Nabble.com.

Hi Thank you both for the responses. I am going to opt instead to get users to put a comment once they've read the document (This is a requirement for one of our certifications - that users confirm they've read a document). This is probably a better and simpler option anyway. Thank you again for your help. I am loving XWiki!!

Hello, In my XWiki application, I have a Sheet + Class with a property with textArea/wysiwyg type. I use public String display(String fieldname, String mode) http://maven.xwiki.org/site/docs/xwiki-javadoc-5.0.x/com/xpn/xwiki/api/Docu… Unfortunaly in view mode all values are rendering between . How can I remove them? An example, in edit mode, in my textArea/wysiwyg, I have ----------------- Some text bold 1. first 2. second ----------------- In view mode I obtein: Some text bold 2. first 3. second (I must reinit counter list too) HTML code: Some text bold <ol> <li style="list-style-type: none"> </li> <li> first </li> <li> </ol> Of course i cannot remove or modify style because I want to keep this one: bold Thxs for any help Pascal B
