[xwiki-users] Problem with a 1.8 RC1 install
by Thomas Eveilleau 24 Feb '09

24 Feb '09

Hello, Yesterday we tried to install a 1.8 RC1 on a serv to test some new features but we had some blocker issues : no users listed in the admin page, no groups listed in the admin page, not any document listed in the WhatsNew etc. We first thought that it was a JS issue, but a : #set ($sql = "where 1=1") #set ($list = $xwiki.searchDocuments($sql)) {pre} $list {/pre} returned an empty list. Here is the description of the install : - We used a Debian Lenny 5.0 template (with Tomcat 6.0.18 & Java 1.6.0_12 pre-packaged) - We downloaded the .war file on http://maven.xwiki.org/releases/com/xpn/xwiki/products/xwiki-enterprise-web… - We installed Mysql with the debian package (5.0.51a-24 version) - We installed & configured the XE in UTF-8 - We used the standard hibernate conf (just added UTF-8 conf) - We kept the standard xwiki.cfg (+UTF8 elements) - We imported the xwiki-enterprise-wiki-1.8-rc-1 xar (found on XWiki.org) - We tested with different mysql-java-connector (current version : 5.0.7) The install is available here (if you want to check it) http://testapplis.xwiki.com/ The Whats New page here : http://testapplis.xwiki.com/xwiki/bin/view/Main/WhatsNew Have you got any idea of the problem ? Thanks, Thomas

I was using the script below. the idea is: - object should have "owner" and "contributors" - "owner" and "contributors" have edit rights - initially, "owner" is set to the document creator There where a few problems with this. $ownr = $doc.getCreator() would fail, so I reverted to $ownr = $context.user. also, save() failed, so I rely on the user saving the document. ---------- code ----------------------- #if ((!$ownr || $ownr == "") && !$doc.getURL.endWith("ClassSheet")) #set ($ownr = $doc.getCreator()) #if (!$ownr || $ownr == "") #set ($ownr = $context.user) #end $doc.set("Owner",$ownr,$obj) #end #if (!$obj.Contributors) #set ($contributors = "") #else #set ($contributors = $obj.Contributors+",") #end ##if ($context.user == $ownr) #set($editors = $contributors+$ownr) #macro(allowEdit $users) #if($users && $xwiki.checkAccess($doc.getFullName(),"edit")) #set ($rights = $doc.getObject("XWiki.XWikiRights", true)) #set ($result = $rights.set("levels", "edit")) #set ($result = $rights.set("users", $users)) #set ($result = $rights.set("allow", 1)) ## $doc.save() #end #end #end ---------- /code ----------------------- I think the problem was that either the classsheet had XWikiGuest set as owner, and that was copied, or that the property was set when an unauthorised viewer visited the document. I now added: #if ((!$ownr || $ownr == "" || $ownr == "XWiki.XWikiGuest") && ! $doc.getURL.endWith("ClassSheet")) but I still think something here is a strange. > One more thing, is there a reason why Patterns.PatternClassSheet uses > #includeInContext("scripts.DesObjClassSheet") instead of > #includeMacros("scripts.DesObjClassSheet")? I'm not sure, I think I wanted to pass on some global variables, and so I thought I needed to include the whole page in context rather than the macros. I've changed this now, we'll see what happens. thanks!!

[xwiki-users] disable footer information
by MrMela 24 Feb '09

24 Feb '09

Hello everybody, maybe this is a stupid question but... in the release notes of new version 1.8 RC1 i can see "Make it easier to disable footer information (comments, history, etc)" Now the question is: How? Maybe it is easier, but it still remains too difficult for me :confused: Thank you in advance -- View this message in context: http://n2.nabble.com/disable-footer-information-tp2377081p2377081.html Sent from the XWiki- Users mailing list archive at Nabble.com.

Dear all, I am trying to render strings using velocity while i am in inline mode, but every time, i got an input form with my value inside. How can i get my variable well displayed ? Here is my piece of code (with different tries): $context.setDisplayMode("view") #set($a="${backlogId},${domainId},${topicId},${epicId},${temp}") $doc.display($a) $a <a href ="/xwiki2/bin/view/Project/addActor?usId=${a}">Add an actor</a> (Note, a is not rendered when using $doc.display($a) and is always replaced by : <input size='30' id='XWiki.USClass_0_id' value='1,0,0,1,2' name='XWiki.USClass_0_id' type='text'/> instead of '1,0,0,1,2' ) Thanks in advance for your help Jean -- ---- Jean Couteau Code Lutin - http://www.codelutin.com 44 Bd des Pas Enchantés - 44230 St-Sébastien/Loire Tél : 02 40 50 29 28 - Fax : 09 59 92 29 28

[xwiki-users] Give a new image with a link
by Hervé Agnoux 23 Feb '09

23 Feb '09

Hi, I should want a special link, in a xwiki page, so that when man clics on it, he get a new image (for instance, a clock with the hour of the clic). I suppose I need groovy. I know how to do an image with java, and I presume with groovy, but I don't understand how to embedded that in xwiki. I suppose I need to create a special servlet, but how this servlet is created and inserted in xwiki by the groovy mecanism ? Thank you for your help.
