Is there an easy way to hide a space (navigation, search, what's new)
by Thomas Arthur Oehser 19 Mar '07

19 Mar '07

Hi- I think I need something like a space preference that allows certain spaces to be "hidden" in places where their existence would show. My usual configuration is: public-topic-space public-topic-space limited-or-private-space I can already set roles that control who can _use_ the private space, but I often want it to be _completely invisible_ to public users. This includes: - Navigation panels - Search results - "What's New" pages - Everything else This is for when a virtual xwiki is overkill, but some spaces should not appear at all in any way other than to users who have the rights. -Tom -- May 4, 1970: Alison Krause, Jeffrey Miller, Sandra Scheuer, William Schroeder.

Panels layout problem
by Oskar E. Skeide 19 Mar '07

19 Mar '07

Hi, I tried to set the Panel on the left side, so in "Panel Wizard" I chose "Left column" as page layout and saved this. Now all my Panels are gone. Tried to "Revert " and I tried changing to "Right Column" but still the layout resets to "No Side column". Is this a know bug, or is it just me ? -- if(!Coffee.Exists) { me.Dispose(); throw new NullCoffeeException(); }

Question about roles for skins, skins not working on registration,
by Thomas Arthur Oehser 19 Mar '07

19 Mar '07

Hi- I'm really struggling to get the xWiki to a point where I can expose it to the real Internet. I'm having a _lot_ of trouble getting security to work tolerably. ? What roles control skin access? I have: Global XWikiGuest register allow Global XWikiGuest comment deny Panels XWikiGuest view allow XWiki XWikiGuest view allow But, registration still doesn't work. The skins and stuff are denied, and the registration page pulls disastrous javascript errors, too. There isn't a "Skins" space, though, to give them access to- panels and xwiki didn't do it- what gives? Also, ? How to set up the email validation? I turned it on and put reasonable text in the email stuff, and the email is sent... but, I don't see a generated confirmation number- now the user gets a form wanting the confirmation number- what is configured wrong? I'm using the tips within the last couple of days. -Thanks for any help, -Tom -- May 4, 1970: Alison Krause, Jeffrey Miller, Sandra Scheuer, William Schroeder.

How to Use Internationalization
by ning wang 19 Mar '07

19 Mar '07

Hello all, I want to change XWiki between various languages. I read the page http://www.xwiki.org/xwiki/bin/view/UserGuide/I8N which says "You can easily setup and change your XWiki language settings on the Preferences page." But I can't find how to setup various languages. Would you please give me some suggestions? Thanks, Sincerely, Wang Ning

By the way, forgot to mention that the technique below does not grab attachments. If anyone has suggestions on how to get attachments included, I would appreciate tips.Stephen From: stephen_schaub_88(a)hotmail.com I thought I would share a tip for downloading a static HTML snapshot of an XWiki space.

banner & footer
by fabrice régnier 17 Mar '07

17 Mar '07

hi all ;) How can I easily modify the xwiki banner & footer in the same way i can modify the Menu & Toolbar ? Btw, are Menu and Toolbar pages the same items that belongs to the admin pages 'right panel' and 'left Panel' ? I assume yes. Well, it seems i can't make them hidden in all the wiki even if i choose 'No' in XWikiPreferences?xpage=editprefs (Thems). I've seen in the FAQ that i need to build a new skin to hide the panels. It is still true ? or should i just check the yes/no option ? regards, f.

Caching of arbitrary objects
by THOMAS, BRIAN M (ATTSI) 16 Mar '07

16 Mar '07

I have a page that is a mashup of two internal web services - one that serves organization structure, and another that serves IM presence indicators - to produce a team listing for each of the groups that own the content of one of our XWiki instances. Because queries to the first are costly and their content is updated infrequently, a caching mechanism is indicated. I see two ways of doing this: one is to manipulate the URL object for the outgoing request to provide for normal HTTP caching disciplines. I'd prefer to do it this way, but haven't a clue at the moment of how to do it, since it's inside org.dom4j.io.SAXReader, to whose read(String) method I pass a URL. Another way that I'd like to investigate in parallel is simply to use XWiki's caching mechanism to cache the parsed org.dom4j.Document objects that are returned. Establishing a new cache with a Velocity script seems straightforward (though of course it requires programming rights): #set($myCache = $xwiki.xWiki.cacheService.newCache()) $mycache.put("name", $myObject) $myCache.get("name") ... etc... but it suffers from two problems: first, it's only in the context of the request, making it useless; second, there's no way to manage the freshness exception thrown from the get methods. So apparently a plugin is indicated; ideally, one that: could be used for any purpose; provided simple means of specifying cache parameters, such as the freshness rules and the operation required to refresh the cache. I think that the best way to use it would look something like: #set($myCache = $xwiki.myCachePlugin) $myCache.setParameters(...) $myCache.cached('$velocityCode') ## should pass the Context, or is that part of the plugin API? The method would use the unrendered Velocity code as the key to the cache, look first in the cache and return it, rendering the code and caching its result first if the value was not fresh. In describing this, I'm thinking that the DefaultPlugin actually provides for a lot of this. Thoughts, anyone? brain[sic]

Easy to set object properties from strings?
by THOMAS, BRIAN M (ATTSI) 16 Mar '07

16 Mar '07

Brief background: I have a servlet filter that handles authentication. It wants to auto-register previously unseen users, and update already-registered users, from information in cookies. The information is mostly in the form of strings, but the object's fields might not be. The question: Is there a simple, type-independent method to set an XWiki Object field's value from a string? The question is not "how can this be done", since I can easily work that out, but rather "is there a method currently available"? brain[sic]

Hi, Oskar, Completely new to xWiki I'm afraid I can't be of much help. But I think there is a clear thing: documents are in the database! HTH, Ricardo -- Ricardo Rodríguez Your XEN ICT Team >>> Oskar E. Skeide<oskaremil(a)gmail.com> 1/3/2007 15:49 >>> OK, I guess I just have to edit the document then, to ensure a proper formatting. But when I choose the "Edit" option it seems like it's only the content DIV I can edit. I guess I have to find the document in my filesystem and edit it from there. Problem is, I can't find that document. Where are the WXiki documents stored ? I cannot find them anywhere in [TOMCAT_HOME]/webapps/xwiki/
