[xwiki-users] Diagnosing empty start page
by Bryn Jeffries 25 Aug '16

25 Aug '16

Hi, It's been a while since I've installed XWiki from scratch, and last time it was for Ubuntu 14 with 7.1.1. It looks like enough things have changed since then that I'm doing something wrong. I'd appreciate any help in diagnosing the problem. This time I'm using Ubuntu 16.04.1 and Tomcat 8. I'm installing from the debian/Ubuntu xwiki-enterprise-tomcat8-pgsql package version 8.2.1, with Tomcat8 package 8.0.32-1ubuntu1.1. It's running (as before) via an AJP connector behind Apache2. https://mysite/xwiki correctly redirects to https://mysite/xwiki/bin/view/Main/ so it looks like something is happening, but I'm getting an empty page. The following are the Catalina log entries (please excuse the length) from restarting tomcat onwards. My experience has been that one always gets some warnings, but my guess is that one or more of the following are resulting in pages failing to load. 22-Aug-2016 10:11:46.465 INFO [Thread-11]

by Mathieu QUERE 24 Aug '16

24 Aug '16

Hi Everyone, I installed google app extension. I can see for instance my document on the drive. But when i try to use it for login it doesn't work. The authentication seems working on google but it redirect me to the login page. From there the button "login with google" doesn't work. Here is what i did: my user in google is mathieu(a)rest-soln.com I created a user in xwiki and the login is mathieu and this user is admin. I read it on a website. then i try to login with mathieu(a)rest-soln.com. Then i redirect to this URL: http://xxxx:8080/xwiki/bin/login/XWiki/XWikiLogin?srid=aZKKwbDe&xredirect=%… do i need to do something else in xwiki? do you have documentation?

Re: [xwiki-users] Debian installation failed

Sure any improvement to the documentation is welcome but I would probably present this more as a special Debian Jessie step that somethings everyone have to check (or maybe add this to a troubleshoot section for the others). As you want. Le 23 août 2016 17:05, "Eugen Colesnicov" <ecolesnicov(a)gmail.com> a écrit : Thomas Mortagne wrote > Actually looks like you have it in jessie-backports but it's probably > not enabled by default. Thomas, you are right. Need to edit /etc/apt/sources.list and add this line: deb http://ftp.de.debian.org/debian jessie-backports main After this openjdk-8-jdk will be installing without problem. But as I said, for non-professional in linux - it is not so clearly :) Maybe will reorganize InstallationViaAPT instruction? (http://platform.xwiki.org/xwiki/bin/view/AdminGuide/InstallationViaAPT) For example, can be possible to rename "second step" to "third step", "first step" to "second step" and add new "first step" with something like this: ... first step - you should install or check availability of openjdk-8-jdk package. For example in Debian Jessie need to add jessie-backports to repository sources-list ... If you agree, I can do it. -- View this message in context: http://xwiki.475771.n2.nabble. com/Debian-installation-failed-tp7600759p7600805.html Sent from the XWiki- Users mailing list archive at Nabble.com. _______________________________________________ users mailing list users(a)xwiki.org http://lists.xwiki.org/mailman/listinfo/users

[xwiki-users] Use file path in office macro
by Hofstätter Mario 23 Aug '16

23 Aug '16

We currently display an attached excel file on a wiki page using the office macro and syntax {{office filterStyles="false" reference="attach:MyFile.xlsx"/}}. Instead we'd like to use the path of an file saved on our server, a working url for this is [[unc:\\serverhostname\folder\folder\MyFile.xlsx]] However, {{office reference=" unc:\\serverhostname\folder\folder\MyFile.xlsx " filterStyles="false"/}} does not work (Failed to view office attachment). The Office Macro documentation states: "The supported resources are URLs (url:) and attachments (attach:)." Is there currently a way to use a file path with the office macro? I tried variants using url: but none of them worked. Thank you. Mario

[xwiki-users] A problem with xwiki macros
by Edward Knyshov 22 Aug '16

22 Aug '16

Hi. I'm trying to customize permissions in xwiki using ApplicationReadyEventListener. I override some permission in XWikiPreferences XWikiGlobalRights page to get page deletion work by default for all users. https://gist.github.com/edvorg/4e2771ac02c4c64b705127964bc53c64 I set up permissions in these functions. https://gist.github.com/edvorg/da7f8e64a46b7bbbf16f953e3fcc0e30 This solutions works fine. But I got a problem with fresh xwiki bootstrap. Sometimes I get fully broken xwiki - all macros shows error. And I have something about admin user not having permission to edit some page: https://gist.github.com/edvorg/1bdec91e5483307696bc68841d2cb1d8 I tried to debug all this code but it doesn't make much sense to me. I only found that this CacheChecker thing somehow affects the issue. Could someone point me to possible issues in my solution and maybe describe how this CacheChecker should be used? I would appreciate any help, as we can not get rid of xwiki integration bugs for a long time. Thank you!

[xwiki-users] Migration to nested pages
by D R 21 Aug '16

21 Aug '16

Hi folks, I upgraded XWiki from 7.0.1 to 7.4.4 which went fine. After checking everything is ok I ran the nested pages migration application and noticed some things I have questions on: 1. After migrating my main wiki the heading "Wiki Home" was replaced by "$services.localization.render('xe.home.title')". Sub wikis didn't have this side effect. Maybe a bug in the migrator? 2. After migration I noticed that the spaces that were previously right below Main stayed but are hidden now. In addition all spaces are now below the node "XWiki Bereich" (German for "XWiki Space") as nested pages. Creating new pages on the main page are placed right on the main page and directly below the wiki node in the tree. Example: * Home / XWiki Space / Migrated Space / Sub docs * Home / New Page / Sub docs In the database they look like this: * xwikidoc ** XWD_NAME: WebHome; XWD_TITLE: Migrated Space; XWD_PARENT: Main.WebHome; XWD_WEB: Main.Migrated Space ** XWD_NAME: WebHome; XWD_TITLE: New Page; XWD_PARENT: subwiki:Main.WebHome; XWD_WEB: New Page * xwikispace (2 entries for the migrated space) ** XWS_REFERENCE: Migrated Space; XWS_NAME: Migrated Space; XWS_PARENT: null; XWS_HIDDEN: 1 XWS_REFERENCE: Main.Migrated Space; XWS_NAME: Migrated Space; XWS_PARENT: Main; XWS_HIDDEN: 0 ** XWS_REFERENCE: New Page; XWS_NAME: New Page; XWS_PARENT: null; XWS_HIDDEN: 0 I'd like to achieve a "sane" hierarchy which shows the migrated spaces directly under the wiki node but before deleting anything or doing database changes I'd like to know the community suggestions. Thanks in advance for some hints. Regards, Dennis
