[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 ?

Hi devs, Just wanted to keep you abreast of what I'm working on. Right now I'm refactoring the Velocity Subsystem so that it works as described in the attached flowchart diagram. This is really schematic so let me know if something is not clear in the diagram. Let me know also if you have some input (improvements, things you don't like, etc). Thanks -Vincent

--------------------------------------------------------------------------------------------------------------- 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

Attaching an image from another document?
by Vincent Massol 22 May '08

22 May '08

Hi, I'd like to attach an image to the current document but the image is attached to another document. I couldn't find the answer in the FAQ. It would be great if the {image:} radeox macro allowed for this. Right now the only solution I'v found (which is a bit ugly) is to use an HTML <img> tag as in: <img src="/xwiki/bin/download/XWiki/Toolbar/image.gif" /> Any other solution I would have missed?

[xwiki-devs] Roadmap for JCRStore/QueryPlugin
by Artem Melentyev 22 May '08

22 May '08

Hi, devs. Here is tentative roadmap for new JCRStore + QueryPlugin: I'll write a proposals about everything important things to do. Millstone1, jcrstore renew: store system refactoring: make stores as components (but they still be in xwiki-core) introduce new query manager in store (low-level, support of HQL | XPath,JCRSQL depending of store) remove duplications in Hibernate & Jcr stores move jcrstore out of xwiki-core (~ xp-core/xwiki-jcr) support of recent Jackrabbit & eXoJCR write functional test suite for store system. final proposal of new QueryPlugin result: jcrstore runs in functional test suite for store system. deadline = June 20 = XE 1.5M2 (feature freeze for XE1.5) Millstone2, queryplugin renew: implement new QueryPlugin for both Hibernate&Jcr stores. rewrite hql queries in XE with QueryPlugin. implement remained things in JCRStore result: XE fully works on JCR. deadline = ~10 July So XE on JCR will fully works since 1.6M1 at least. WDYT? -- Artem Melentyev

[xwiki-devs] distict blog authors
by Glenn Everitt 22 May '08

22 May '08

Hello XWiki-Dev's I'm trying to figure out how to create a list blog authors but I want the authors to be listed only once so I'm trying to figure out how to create a "where" clause for searchDocument. I thought if I found all of the Documents with XWiki.ArticleClass as a BaseObject and then used distict I could create a list of Blog authors. One problem is that it looks like searchDocuments doesn't allow me to specify distinct. I'm unclear how to refer to doc.author in the query would that be: StringProperty as prop ? First Try #set ($sql = ", BaseObject as obj where doc.fullName = obj.name and obj.className = 'XWiki.ArticleClass'") #set ($start = 0) #set ($nb = 50) #set ($collect = $xwiki.searchDocuments($sql , $nb , $start)) Is there a better way to do this?

[xwiki-devs] Passing values from Velocity templates to HTML on the wiki page
by Kamna Jain 22 May '08

22 May '08

THANK YOU SERGIU. About my question on passing values back from .vm file to the wiki page where I call the .vm file: The reason I am using a template is that there is a select box on that wiki page and some information needs to be fetched based on the value user selects. To be able to use the value selected by the user, I need to do an HTML Post first. so, I submit the form and the values are processed by a template and now I need to display the value calculated in the template, on my xwiki page. I tried some stuff but did not work. So, now I am actually creating an object on that page and set its properties with the value calculated in the template. any other better way of doing this? Is it possible to access the selected value on the wiki page without doing a post? what does $!{value} provide...I do not understand the ! before the variable name. On another note: In the object solution for this problem, I try to set the object property (of type Number) with a velocity variable which also has a numeric value. when I save the document after setting the object values, it gives me an exception on the "save" method. Error number 3201 in 3 Wrapped Exception: java.lang.Integer I checked the type of Number for that property and changed it from long to Integer in the class editor but, it still gives this error. I am also setting a boolean value in the object. I noticed that the boolean fields take values 0 or 1 but display them as No or Yes. So, when we "get" we get Yes/No and when we "set" we have to set 0 or 1. could that be causing the exception? I ma not sure what is causing this exception. but when I hit the back button, I see the values of the object properties set appropriately and displayed. Only when I do the $response.sendRedirect with "save", it throws the exception. Do I need to use Util.parseInteger or Util.toNumber in any of these cases (before setting the Object property value to a number) Please advice. Thanks a lot Kamna

[xwiki-devs] Miscellaneous Questions
by Kamna Jain 22 May '08

22 May '08

Hello Devs, Sachin, thnaks for your response to that mail. I will try that idea. I have questions regarding a few miscellaneous topics: 1) Watch List - Is there anything we need to add/modify in order for the Watch list notifications to work? -> I have the email ids in the user profile -> have 2 pages being watched -> the xwiki.cfg has the watchlistplugin and the mailsender plugin included -> I came across a watch.vm and watchlistrss.vm in the templates folder..but nothing for mail... -> also, in the menuview.vm, just where the Watch menu begins, there is a comment: We're disabling the Watchlist menu for now since the Watchlist doesn't work yet in multiwiki ## mode. Remove when http://jira.xwiki.org/jira/browse/XPWATCHLIST-4 is fixed. What is this for? Please advice on how to get it to work. 2) We have noticed that every time a person logout of Xwiki and logs back in, Xwiki redirects the ser to the page where he hit the logout! This becomes an issue when a different user logs in on the same PC and he would expect to be redirected to the home page, but instead he is taken to some othe rpage. I am looking at the login.vm - the first few llines: #if($context.user!="XWiki.XWikiGuest") #if($request.xredirect) $response.sendRedirect($request.xredirect) #else $response.sendRedirect($xwiki.getURL("Main.WebHome")) #end #elseif($doc.fullName != "XWiki.XWikiLogin") #set($qs = "") #set($qs = $request.queryString) #if(!$request.getParameter("xredirect")) #set($qs = "xredirect=$util.encodeURI($doc.getURL('view'))&${qs}") #end $response.sendRedirect($xwiki.getURL("XWiki.XWikiLogin", "login", $qs)) #else ### ### Login page ### ### -> Do I need to change anything here. What does $request.xredirect return? Please indicate which lines need to be altered/commented, so that users are always directed to home page when they log in. Kindly help. Waiting for your responses. Thanks

[xwiki-devs] Big ThreadLocal patch coming...
by Vincent Massol 22 May '08

22 May '08

Hi devs, I'd like to commit my big threadlocal patch. What it does is the following: * introduce a new VelocityManager component with 2 methods: getVelocityContext() and getVelocityEngine() that have to be used from now one whenever code needs to get the velocity context or evaluate some velocity templates. Note that these methods are called in the XWikiVelocityRenderer for now so nothing to change elsewhere for now. * initialize the new Container objects (request, response, session) in places where threads are created. This is required because request, response and session are saved in ThreadLocal variables so that we don't have to pass them to all methods. * All this is required for me to implement the new VelocityMacro in the new rendering mechanism since that component needs access to the VelocityContext and VelocityEngine but without using the old code... Since this is a complex patch it's very likely it'll break things. I've tested several cases and it seems to be ok but I'm pretty sure there'll be edge cases that may not work. I'd still like to commit since it's getting big and I'd rather we commit it now rather than later since we're still in 1.5M1 stage. I also need to progress on the new rendering mechanism and this is prerequisite code. Let me know if you're ok. Thanks -Vincent

[xwiki-devs] LDAP Bind fails for one user
by Leen Toelen 22 May '08

22 May '08

Hi, I am using these ldap settings in my xwiki.conf (version 1.3.1 Enterprise) to connect to an Active directory. xwiki.authentication.ldap=1 xwiki.authentication.ldap.authclass=com.xpn.xwiki.user.impl.LDAP.LDAPAuthServiceImpl xwiki.authentication.ldap.server=myservername xwiki.authentication.ldap.check_level=1 xwiki.authentication.ldap.port=389 xwiki.authentication.ldap.base_DN=dc=mydomain,dc=com xwiki.authentication.ldap.bind_DN=mydomain\\{0} xwiki.authentication.ldap.bind_pass={1} xwiki.authentication.ldap.UID_attr=sAMAccountName xwiki.authentication.ldap.fields_mapping=name=sAMAccountName,last_name=sn,first_name=givenName,fullname=displayName,mail=mail,ldap_dn=dn xwiki.authentication.ldap.validate_password=0 xwiki.authentication.ldap.update_user=1 xwiki.authentication.ldap.trylocal=1 (all other ldap setting are commented out) Now most users can login without a problem, but one user gets the following error in the log and cannot login: 2008-05-22 09:49:12,681 [http://wiki/xwiki/bin/loginsubmit/XWiki/XWikiLogin] [P1-15] ERROR LDAP.LDAPAuthServiceImpl - LDAP Bind failed with Exception Invalid Credentials Yet I am sure I use the correct password (since it is the same as his windows password), and tried changing my windows domain password to verify that xwiki correctly checks it (which it does, I needed to enter my new password in xwiki). When I change the user password of the user whch can not login, the problem stays the same. The ldap bind message does not appear for all other users, so I do not think that xwiki falls back to a local user database. Does anyone have an idea what might be causing this? Regards, Leen Toelen
