[xwiki-users] Trying to use $doc.documentReference as the documentTree root
by simmsj 23 Jul '16

23 Jul '16

I'm trying to list the children of the current page. According to this post: http://lists.xwiki.org/pipermail/users/2015-December/031639.html, I believe this should work, but all I get is "No pages found": {{velocity}} {{documentTree root="$doc.documentReference" /}} {{/velocity}} If I use {{velocity}} $doc.documentReference {{/velocity}}, the correct value is returned. Can anyone tell me what I'm doing wrong or if there is a better way to list all the children of the current page? Thanks, Jared -- View this message in context: http://xwiki.475771.n2.nabble.com/Trying-to-use-doc-documentReference-as-th… Sent from the XWiki- Users mailing list archive at Nabble.com.

[xwiki-users] Menu Application subwikis MenuMacro
by Jaume Giribert Peraire 22 Jul '16

22 Jul '16

Hi, Sorry if this topic has been already exposed but I was unable to find any reference in any past emails. We have a 7.4 xwiki installation with multiple subwikis and we want to install Menu Application for every wiki. I just launched a farm installation from Principal wiki and everything seems to work fine but we have found an strange issue. If user has permissions in the last subwiki where Menu Application has been installed he's able to see menu with styling. However, if another user has only permission to an specific wiki (i.e. local user) he can see the menu but no styling is applied. After some browser debugging we have found that Menu Application is making this call for EVERY subwiki. <DOMAIN>/xwiki/wiki/<SUBWIKI>/ssx/Menu/MenuMacro?language=en&colorTheme=xwiki%3AFlamingoThemes.Charcoal The SUBWIKI param is always the same and matches the last subwiki where Menu Application has been installed. Is there any way to make this call like this: <DOMAIN>/xwiki/wiki/<CURRENT_SUBWIKI>/ssx/Menu/MenuMacro?language=en&colorTheme=xwiki%3AFlamingoThemes.Charcoal Thanks in advance!

[xwiki-users] White spaces around images in exported pdfs
by Alina Kupgisch 21 Jul '16

21 Jul '16

Hi xwiki team, i get big white spaces around my images in the exported pdfs, after making the images smaller on our wiki pages. I tried changing the margin, padding, and the border size of the images in the css (used for the pdf export) but that didn't change anything. The background of the image in the exported pdf is bigger than the image itself (i changed the background color for evaluation). Best regards Alina

[xwiki-users] Need Help Installing XWiki on Ubuntu Server 1404 LTS
by Jared Simms 20 Jul '16

These are the steps that worked for me installing XWiki on Ubuntu Server 16.04.01 LTS with Jetty and Postgres. I have double checked most of these steps, but not all of them so your mileage may vary.

[xwiki-users] Disable Registration and View Default Skin at Login
by Jared Simms 20 Jul '16

20 Jul '16

Hello, I would like to disable registration so wiki accounts must be created by an admin. I followed the instruction on this page: http://lists.xwiki.org/pipermail/users/2016-February/032129.html to only have Register checked for the XWikiAdminGroup, but users are still able to register and log in. I can't find the Guest user to remove the Registration right from that user as well. Does the Guest user still exist in 8.1 and is that still the correct way to disable registration? I would also like to display the default skin on the login page. This page http://lists.xwiki.org/pipermail/users/2011-July/020305.html recommended allowing unregistered users to view the default skin, but I have checked "Prevent unregistered users from viewing pages, regardless of the page or space rights" on the Administration: Rights page which seems like it will override any permissions I set on the default skin. The page that looks like it should be the right one is bin/view/XWiki/DefaultSkin, but clicking on the sprocket only gives me the option to "Administer Parent". Is there a way to enable the default skin for the login screen while still disabling unregistered users to view anything other than the login screen? Thanks, Jared

[xwiki-users] Images of included pages are not diplayed
by Alina Kupgisch 20 Jul '16

20 Jul '16

Hi, i used the "include" macro to include pages and sections in a new page, but the images that where attached in the included pages/sections are not displayed. Instead the image names are shown. Our "include" marco has version 8.1, like the Xwiki version. I found the ticket http://jira.xwiki.org/browse/XWIKI-6196 that describes my problem. But this should be fixed since version 3.0. Is there any solution for the problem or do i have to use the workaround that is mentioned in the ticket? Best regards and thanks in advance! Alina

[xwiki-users] OutOfMemoryError: GC overhead limit exceeded on a new installation
by Jared Simms 20 Jul '16

Setting the permanent directory resolved the issue with the Distribution Wizard. Sorry I missed your answer the first time you sent it. Thanks again for the help getting us up and running. - Jared > Vincent, > > You are my hero. I was editing the JVM settings in /usr/share/jetty9/bin/jetty.sh, but they were not being used. Once I applied them to /etc/default/jetty9 the memory errors disappeared. I tested on the current install and then built the whole server from scratch and the Distribution Wizard finished without any errors and I've been able to work in the wiki without any issues. The performance is on par with the standalone instance as well. > > The only piece that doesn't seem to be working right is the Distribution Wizard still starts every time I start XWiki. Is there something I need to do so that doesn't happen? Actually I answered that question in the previous mail I sent you. "Indeed that’s not the normal behavior ;) The only reason I can think of is that you’ve not configured the xwiki permanent directory location and it’s using some temporary directory by default and for some reason you’re clearing that directory every time before restarting XWiki. “ Have you checked the permanent dir location?

[xwiki-users] XWiki.Tableview - Pages on this Wiki Empty (7.4.4)
by Stev Williams 20 Jul '16

20 Jul '16

Hi, I am having problems getting the index application in tableview to show any pages. I am not sure when this happened but uninstalling and re-installing the Index application both using the extension manager and manually appears to have not fixed the issue. Checking Tree, Attachments, Deleted Pages and Deleted Attachments they all appear to be working fine. The URL it is going to is /xwiki/bin/view/Main/AllDocs Is there anything else I can try to get the page working?

[xwiki-users] OutOfMemoryError: GC overhead limit exceeded on a new installation

Vincent, You are my hero. I was editing the JVM settings in /usr/share/jetty9/bin/jetty.sh, but they were not being used. Once I applied them to /etc/default/jetty9 the memory errors disappeared. I tested on the current install and then built the whole server from scratch and the Distribution Wizard finished without any errors and I've been able to work in the wiki without any issues. The performance is on par with the standalone instance as well. The only piece that doesn't seem to be working right is the Distribution Wizard still starts every time I start XWiki. Is there something I need to do so that doesn't happen? Thanks again for the help. - Jared

[xwiki-users] OutOfMemoryError: GC overhead limit exceeded on a new installation
by Jared Simms 19 Jul '16

19 Jul '16

Thanks for the suggestions. I tried removing the garbage collection parameters but still got the out of memory errors so I tried removing all the Java parameters and got the same behavior. Vincent, I started with "-Xmx1024m" but increased it to 2048m after getting the out of memory errors and reading the page you referenced (http://platform.xwiki.org/xwiki/bin/view/AdminGuide/Performances#HMemory) I also used the parameters and values that page referenced as what is used on the xwiki.org site. The other odd thing is that every time I restart Jetty, the Distribution Wizard starts. This is my first experience with the Distribution Wizard, but I'm guessing that isn't the expected behavior. It even starts up when I restart Jetty before running into the out of memory errors. I probably also should have mentioned that the VM I'm trying to run xwiki on is configured with 8GB of memory and 4 vCPUs. Any other suggestions for how to get a stable installation running? Thanks, Jared This is the most recent error I got during testing this morning: 2016-07-19 07:56:20,847 [http://nhhqwiki01:8080/xwiki/bin/view/Infrastructure/Policies%2C+Process%2C…] ERROR
