select objects by class and sort by property
by Brian D. Switzer 12 Dec '05

12 Dec '05

I'd like to select documents from the database by class via the following (based on the blog code): #set ($sql = ", BaseObject as obj, DBStringListProperty as prop join prop.list list where obj.name=doc.fullName and obj.className='Photos.PhotoClass' and obj.name<>'Photos.PhotoClassTemplate' and obj.id=prop.id.id and prop.id.name='category' and list='${category}' order by doc.name") This is fine, but I'd like to sort the results by another of the parameters ("date") instead of by document name. I'm not a database person, so I'm not sure how to accomplish this. Any guidance would be most helpful. -- Brian D.

some xwiki problems.
by Andreas Wüst 12 Dec '05

12 Dec '05

Hi all, i encountered some problems using the xwiki and hope you can help me. i downloaded the latest xwiki version and installed everything using a postgresql database and a tomcat 5.0.29. The following problems occured: 1. The page http://localhost:8080/xwiki/bin/view/Main/WebHome could not be opened for some reason. the browser keeps loading and loading, but nothing happens, not even a timeout. The same problem exists for the "Blog" link: http://127.0.0.1:8080/xwiki/bin/view/Blog/WebHome However the page http://127.0.0.1:8080/xwiki/bin/view/XWiki/Menu can be opened without problems. Logging in as Admin user does work, too. So DB cannot be the problem. Any ideas about this problem? 2. I deleted some page in the wiki, which resulted in lots of execption that i cannot get rid of. at the moment i cannot change anything due to this problem. the exception is org.hibernate.AssertionFailure: possible nonthreadsafe access to session at org.hibernate.action.EntityDeleteAction.execute(EntityDeleteAction.ja va:68) at org.hibernate.engine.ActionQueue.execute(ActionQueue.java:239) .... .... at org.hibernate.transaction.JDBCTransaction.commit(JDBCTransaction.java :86) at com.xpn.xwiki.store.XWikiHibernateStore.endTransaction(XWikiHibernate Store.java:350) at com.xpn.xwiki.store.XWikiHibernateStore.deleteXWikiCollection(XWikiHi bernateStore.java:982) If you need the full exception, tell me. 3. I changed the language under "More Actions" -> "Web Preferences" from "en" to "de". After that it was no longer possible to change anything under "Presentation" the definition for the "XWiki Wiki Web", ... , "Top Menu", "HTTP Meta Information" we all empty and thus could not be edited. Changing the language back to "en" does not work, because i am getting the errors mentioned in 2.) 4. When editing a page i can select the preview, which will show me a preview of the page, which is nice. However the preview page does not contain a back button, that takes me back to the edit page. there is only a save button. so, if i do not want to save the page i have to use the back button of the browser, which is neither good nor consistent. Adding a back button in the html page back to the preview page would be really appreciated. So, my biggest problems are 1.) and 2.) at the moment. i'd really appreciate if you could help me, because i have to set up a wiki and want to use one written in java and xwiki seems to be best non-commercial java wiki. regards, Andreas ___________________________________________________________________________ Andreas Wüst amites GmbH Heumadener Straße 2 73760 Ostfildern phone: 0711-4599939-34 fax: 0711-4599939-63 mailto:andreas.wuest@amites.de http://www.amites.de

xWiki Permissions - I may need the big guy's help!
by Bob Mixon 12 Dec '05

12 Dec '05

Okay, this was a dumb move on my part. :-( I was trying to setup my wiki with the following permissions: * All non-registered users can see everything. * All registered users can edit everything. * Only I can edit the home page. As a result, I somehow downgraded my permissions so I can't do anything. ~ arg ~ The xWiki I am referring to is http://sharepoint.xwiki.com <http://sharepoint.xwiki.com/> - how can I get things restored? <http://bobmixon.xwiki.com> KM, BPM, Intranet and Portal Technologies <http://bobmixon.xwiki.com> The Possibilities are Endless Bob Mixon <mailto:bob.mixon@gmail.com> bob.mixon(a)gmail.com http://bobmixon.xwiki.com/ Skype ID:brm1999 <https://www.plaxo.com/add_me?u=30065756390&v0=1965978&k0=1714165761> Add me to your address book... <http://www.plaxo.com/signature> Want a signature like this?

Blog.Macros may not be working correctly
by bob.mixon＠gmail.com 08 Dec '05

08 Dec '05

Hello, By default, my xWiki site uses the code: #set($category = "$request.category") #set($nbitems = "10") #set($nbstart = $request.nbstart) 1 Entries for category $category #includeMacros("Blog.Macros") to display News/Blog entries on the site. The Blog.Macros code displays a "Next" link at the bottom of the page when the number of items exceeds groups of 10. But the link itself is not being built correctly. If you are specifically viewing a category, the category parameter is dropped from the URL when Next is clicked. What is the best way to get this fixed? Also, I would like to make some changes to the way that information is displayed on my site; such as display 10 complete articles at a time, not excerpts from articles. All help is greatly appreciated.

does xwiki support translations?
by charles gay 08 Dec '05

08 Dec '05

Hi, firstly, thanks to the xwiki team for thier great product! one question: is there any "translation support" in xwiki?: when i see one page with a language preference, i see a specific version of it (english in my example). when i've got a portuguese preference, i see the last version of the page edited with the portuguese label. can i create a page, and associate with it the related translations?(the original page and its translations have got the same url): => the url is the same for all the translations, but i can see translations depending on my language preference. is it the case?(we've created on our wiki, one page per translation.... => http://jguard.xwiki.com ). sincerly yours, Charles(jGuard team).

XWiki forms with database select fields
by Pierre CARLIER 08 Dec '05

08 Dec '05

hello everybody ! I'd like to design a form with one database select field. The xwiki standard distribution provides a good basic example with the Category field within the XWiki.ArticleClass. But some additional information could be helpful : - a relational map of all the database tables involved in this application - the names and descriptions of Hibernate objects corresponding to the database objects so that I can fully undestand queries like this one : select prop.value from BaseObject as obj, StringProperty as prop where obj.className='Blog.Categories' and prop.id.id = obj.id and prop.id.name='name' (standard hibernate query for the category field) - for my current project, I intend to automatically feed this table with data updated in another database by another application software (CRM in that case). So it's crucial to know with precision what XWiki requires when managing "database select fields". Do you know about some existing developments like this one ? Thank you by advance for any information you could send to me ... Pierre Carlier pcarlier(a)repgroup.net

Table Spreadsheet Calculations
by Ron Scott 07 Dec '05

07 Dec '05

There is zero documentation on what kind of spreadsheet functionality works in XWiki tables. The only documented thing is SUM and it is also the only thing I can get to work. Even simple things like =(Address - Address) makes XWiki throw an exception on render. Is there documentation somewhere that explains what can be done in tables? Or is SUM about the, um, sum of it? I just wanted to have one cell subtracted from another cell... is this possible?
