[xwiki-devs] How to add new users before they login?
by shivshan 27 May '08

27 May '08

Hi When using LDAP authentication, is it possible to add users manually before they login for the first time? Is there some way for XWiki to validate that the user exists in LDAP so that it can create an account in the database? In most LDAP implementations, it is possible to query whether a user exists after you are "bound" using your own account and password. The use case is that we already know the users who have to be given specific rights, and would like to grant them the right permission before they login rather than after.

[xwiki-devs] [Strategy] Improving the documentation, giving shorter answers to email questions...
by Vincent Massol 26 May '08

26 May '08

Hi everyone, Here's a strategy that I try to follow and that I think might be good that we all follow. The end goal is to improve the XWiki documentation on xwiki.org. Here's how it goes: 1) someone (A) asks a question on a xwiki list 2) someone (B) knows the answer 3) B verifies that the answer can be found on xwiki.org and if so gives a link to it in the reply to A 4) If the answer is not found on xwiki.org, then B adds it (*) and then gives a link to it in the reply to A In this manner we'll all enrich the xwiki documentation and it'll only take marginally longer to answer questions. The next time someone asks the question again we can simply point him/her to the location on xwiki.org What happens now is that usually people answer in the email, often giving very long and elaborate answers with lots of knowledge/wisdom in it. Then another person comes in, asks the same question and we answer again, etc. The result is: * the xwiki.org documentation is not better * overall as a team we are less efficient (*) One difficult in putting the answer on xwiki.org is to find the right location where to put it. So here are a few tips: * For code snippets, add it to the Code Zone * For questions on how to use XWiki, please add it to the Features guide * For development questions, add it to the Developer's guide * For configuration questions and administration questions, add it to the Administration guide * For other questions, add them to the FAQ Applying my own strategy, you can find the content of this email at http://tinyurl.com/4xfel2 :) Let me know what you think! Thanks -Vincent

[xwiki-devs] XEclipse odd behaviour.
by Enygma 24 May '08

24 May '08

Hi devs. I recently finished my exams and started messing with XEclipse again. I had already worked on debugging XEclipse and it worked pretty well. Now, at the first steps I ran into a (big) bump. When hovering over the page preview, my Eclipse (or XEclipse rcp version) closes abruptly. No exception, no error message. The XEclipse rcp version gives the message "Aborted" upon exit. This is the *best* and *only* feedback I can see when the crash happens. I have recently upgraded to Fedora 9, from 8. On Fedora 8 it was working, not it's not. On a Windows machine it works also (the windows version). I am using OpenJDK 1.6.0. I suspect the problem could be related to the environment (KDE4 or Fedora related). Any suggestions?

[xwiki-devs] Help with the JIRA issue.
by malaka ekanayake 24 May '08

24 May '08

Hi All, I have finished my university academic work and now i'm starting to work on the JIRA issues. I picked http://jira.xwiki.org/jira/browse/XECLIPSE-76 . I looked into it but ran into a small trouble. I can add a method to com.xpn.xwiki.xmlrpc.XWikiXmlRpcHandler to rename a page. But i have no idea how to invoke this method from the client side (Swizzle does not seem to have such method). Your help is very much appreciated. - Malaka. PS: I'm also looking into several other jira issues.

Thanks Jean, for the pointer on setting the Registration prefs. Just wanted to make sure if that is all we need. I have entered my email id as the Admins email id and have entered a valid smtp mail server. should I add anything in the Validation, Confirmation or invitation email content. should I say "Yes" for the first field - Use email verification. it is not set to anything right now! Is there a need to restart xwiki (tomcat) for the changes to take affect! Thanks a lot. Kamna > > > > >* Hello Devs, > *>* > *>* Sachin, thnaks for your response to that mail.

[xwiki-devs] Create List Search Actions
by Ludovic Dubost 23 May '08

23 May '08

Hi, I've continued to make progress on the CRUD actions (which will have to be converted to REST). I've created a "create" action which allows to get a creation form. The name of the page is automatically derived from one of the fields of the page or by a counter as specified in the class config. It calls to the "save" action which has been modified to handle the page name generation as well as being compatible with validation and reloading the create action when you came from creeate. Also a list and create actions have been created. Currently the these actions have to be called on the class document: /xwiki/bin/create/XWiki/ArticleClass would launch create on a blog article. It then create a save URL in the default space set in the class definition and a non existant page. In case of validation error we get to see that intermediary URL in the location bar. I'm not especially happy about this URL since it is not in the "space" of where the document will be created. You could get a right error after clicking Save instead of right away showing a permission error. I could use this type of URL /xwiki/bin/create?class=XWiki.ArticleClass or /xwiki/bin/create/SpaceWhereToCreate/?class=XWiki.ArticleClass or /xwiki/bin/create/SpaceWhereToCreate/XWiki.ArticleClass This is the same with the list and search URLs. Currently it's /xwiki/bin/list/XWiki/ArticleClass it could be /xwiki/bin/list/?class=XWiki/ArticleClass We could also detect the space name and automatically find the class name that defaults to this space for creation. Also I currently have the save code in SaveAction. Now this make the code a little like a hack. Should I move it to a CreateSaveAction ? or another name ? WDYT ?

--------------------------------------------------------------------------------------------------------------- Originally i was using 1.1.1.5166 over mysql 4.1.20. Changing the skin works fine here. I am testing xwiki 1.4 before we put it into production, so i loaded up the database dump from from the production xwiki (v1.1.1.5116) onto a server running mysqI 5.0.58 and xwiki v1.4.9828. Thats where i get the stack trace. I also noticed that with the Toucan skin, the administration tools are messed up. No users/groups show up when you click the tab on the admin page. but when i change the skin to albatross the users/groups show up. Any help is appreciated. Thanks! Marlon
