Is panel wizard broken in b5 ?
by Antonio Goncalves 08 Mar '07

08 Mar '07

Hi, I've downloaded xWiki 1.0beta 5 and tried to use the panel wizard to have both columns. After clicking on "save the new layout" a popup tells me that it's ok ("the layout has been saved properly"). But after, when I go to any other page, the right columns disapears (like if the layout wasn't taken into account). I know that this worked on b4. Was there any changes or is that a bug ? Thanks, Antonio

email user validation, captcha
by Thomas Arthur Oehser 08 Mar '07

08 Mar '07

I must be looking in the wrong places, I'm having trouble setting up either email validation as I would expect it to work, or captcha, and I'm not sure where the documentation is for it... In the 'preferences' tabs (I'm running the svn tips 1674 + b1.5 xar), I have email host and admin email address- which I have sending the email- but, after it sends the confirmation email, the user seems to be actually registered, it isn't waiting for a response, for that matter, there doesn't seem to exist the configurations I would expect of a mechanism for it _to_ listen for a response. Does this mean that I'm supposed to manually set the rights to require a group membership, then manually look for responses? Or create a script that listens for email responses and adds users to the "verified" group? I'm missing major chunks of how to get it to work. Also, I have not found the option or tab or preference (or documentation) for the 'captcha' functionality. Probably I just need to be pointed in the right direction? Desired functionality: - Registration first requires passing a captcha test. - The user enters their email address. - Their verification email is sent, with some kind of GUID. - Their ID is created in some 'locked- waiting for confirm' limbo. - XWiki receives their email and confirms that it has the GUID. - Their status is changed from 'locked' to 'normal registered user'. o What parts of this are currently implemented? o What parts of this are wishful thinking? o Where can I find documentation and help? -Thanks, -Tom -- May 4, 1970: Alison Krause, Jeffrey Miller, Sandra Scheuer, William Schroeder.

Help in choosing a code name for the 1.0 skin
by Vincent Massol 07 Mar '07

07 Mar '07

Hi everyone, In preparation for the 1.0 release we need to rename the current skin which is wrongly named xwiki10b1... I think the best is to not have any version in the name and choose a code name. So here's a challenge to find the best name for the current 1.0 skin (the one used by http://xwiki.org) Shoot! Thanks -Vincent

Instantiating arbitrary Java classes in XWiki pages
by THOMAS, BRIAN M (ATTSI) 06 Mar '07

06 Mar '07

In several instances to date I have found that I can instantiate an arbitrary Java class from a page (with programming rights) if it has a default (i.e. no-parameters) constructor, since java.lang.Class.newInstance() does the trick (where the Class object is obtained by a reference to $xwiki.class). However, to use a non-default constructor, one must use java.lang.reflect.Constructor.newInstance(Object...). Every attempt to do this has failed silently. Indeed, even calling Class.getDeclaredConstructor(Class...) fails; the only way I've managed to get a Constructor object is by looping through the results of Class.getDeclaredConstructors() and picking the one that suits my needs. No errors in logfiles, and so far I haven't even caught it in the act while debugging it under Eclipse. Two possibilities present themselves, though so far my investigation has not yielded any result in either direction: One is that I'm not passing the arguments correctly - in both cases, the argument list is specified in the javadocs as "<typename>..." but in the source, while the formal parameter is an array, other code actually invokes it as a list, as in the case of a C varargs list. Regardless, I can't invoke it successfully either with an array or with a list. The other is Java permissions. Since the Constructor class is in the java.lang.reflection package, and reflection is (I believe) a potentially restricted operation, it may require changing the java.security.Permission configuration. It looks like, for Tomcat, that's accomplished by editing the catalina.policy file. Anyone else have experience in this area? I know I can always create a plugin to handle the necessary object creation, and I may eventually do so anyway because granting the necessary permission to XWiki's libraries may open it too widely, but for the moment, I'd rather not have to... brain[sic]

Problems importing Panels.PanelWizard on fresh beta 4 install
by Dan Murphy 06 Mar '07

Hi, Just installed a fresh xwiki beta 4 on WAS CE 1.1 (and MySQL 5.0.22-Debian_0ubuntu6.06.2). And have a couple of probs :( Appologies in advance for the lenght of the email - that's stack traces for you ;) When I started the server I got a number of warning and errors I've not seen before - are these "normal" ? 16:39:56,995 ERROR [SimpleLog4JLogSystem] RHS of #set statement is null. Context will not be modified. [line 9, column 1] 16:39:56,995 ERROR [SimpleLog4JLogSystem] Left side ($objuser.getProperty("usertype").value) of '==' operation has null value.

Main.WebHome [line 48, column 42] Although they claim to be coming from Main.WebHome, they don't exist at the line referenced in the document (or in the included Main.Dashboard(AFAICS)). Seems like it might be a problem in the skin. Also, When I import the beta 4 XAR, the Panels.PanelWizard failed to import.... I then selected just this page again (from the import wizard) and it imported ok. Is this expected (I was wondering if the dependency on XWIKI.TagClassmean that the XWIKI space needs to imported first... but then I've not seen this behaviour before). Unfortunatly I suspect that the error message showing the reason for the failure was swallowed by the following exception I found in the logs : 16:12:31,021 WARN [RegexTokenFilter] <span class="error">Exception</span>: com.xpn.xwiki.render.filter.MacroFilter@1000100 java.lang.NullPointerException at org.radeox.macro.parameter.BaseMacroParameter.insertValue( BaseMacroParameter.java:142) at org.radeox.macro.parameter.BaseMacroParameter.split( BaseMacroParameter.java:120) at org.radeox.macro.parameter.BaseMacroParameter.setParams( BaseMacroParameter.java:58) at org.radeox.filter.MacroFilter.handleMatch(MacroFilter.java:100) at org.radeox.filter.regex.RegexTokenFilter$1.handleMatch( RegexTokenFilter.java:91) at org.radeox.regex.JdkMatcher.substitute(JdkMatcher.java:48) at org.radeox.filter.regex.RegexTokenFilter.filter(RegexTokenFilter.java :89) at org.radeox.filter.FilterPipe.filter(FilterPipe.java:169) at org.radeox.engine.BaseRenderEngine.render(BaseRenderEngine.java:108) at com.xpn.xwiki.render.XWikiRadeoxRenderer.render( XWikiRadeoxRenderer.java:70) at com.xpn.xwiki.store.XWikiHibernateStore.saveLinks( XWikiHibernateStore.java:1459) at com.xpn.xwiki.store.XWikiHibernateStore.saveXWikiDoc( XWikiHibernateStore.java:305) at com.xpn.xwiki.store.XWikiCacheStore.saveXWikiDoc(XWikiCacheStore.java :100) at com.xpn.xwiki.store.XWikiCacheStore.saveXWikiDoc(XWikiCacheStore.java :94) at com.xpn.xwiki.XWiki.saveDocument(XWiki.java:890) at com.xpn.xwiki.plugin.packaging.Package.installDocument(Package.java :547) at com.xpn.xwiki.plugin.packaging.Package.install(Package.java:488) at com.xpn.xwiki.plugin.packaging.PackageAPI.install(PackageAPI.java :191) at com.xpn.xwiki.web.ImportAction.render(ImportAction.java:90) at com.xpn.xwiki.web.XWikiAction.execute(XWikiAction.java:150) ... 16:12:31,023 WARN [RegexTokenFilter] <span class="error">Exception</span>: com.xpn.xwiki.render.filter.MacroFilter@14001400 java.lang.NullPointerException at org.radeox.macro.parameter.BaseMacroParameter.insertValue( BaseMacroParameter.java:142) at org.radeox.macro.parameter.BaseMacroParameter.split( BaseMacroParameter.java:120) at org.radeox.macro.parameter.BaseMacroParameter.setParams( BaseMacroParameter.java:58) at org.radeox.filter.MacroFilter.handleMatch(MacroFilter.java:100) at org.radeox.filter.regex.RegexTokenFilter$1.handleMatch( RegexTokenFilter.java:91) at org.radeox.regex.JdkMatcher.substitute(JdkMatcher.java:48) at org.radeox.filter.regex.RegexTokenFilter.filter(RegexTokenFilter.java :89) at org.radeox.filter.FilterPipe.filter(FilterPipe.java:169) at org.radeox.engine.BaseRenderEngine.render(BaseRenderEngine.java:108) at com.xpn.xwiki.render.XWikiRadeoxRenderer.render( XWikiRadeoxRenderer.java:70) at com.xpn.xwiki.store.XWikiHibernateStore.saveLinks( XWikiHibernateStore.java:1459) at com.xpn.xwiki.store.XWikiHibernateStore.saveXWikiDoc( XWikiHibernateStore.java:305) at com.xpn.xwiki.store.XWikiCacheStore.saveXWikiDoc(XWikiCacheStore.java :100) at com.xpn.xwiki.store.XWikiCacheStore.saveXWikiDoc(XWikiCacheStore.java :94) at com.xpn.xwiki.XWiki.saveDocument(XWiki.java:890) at com.xpn.xwiki.plugin.packaging.Package.installDocument(Package.java :547) at com.xpn.xwiki.plugin.packaging.Package.install(Package.java:488) at com.xpn.xwiki.plugin.packaging.PackageAPI.install(PackageAPI.java :191) at com.xpn.xwiki.web.ImportAction.render(ImportAction.java:90) ... more removed for the sake of sanity :) Any advice ?

Running XWiki on JOnAS : tempdir not set
by Xavier MOGHRABI 06 Mar '07

06 Mar '07

Hi All, I've installed XWiki on JOnAS 4.8.4 and I have some problems. I start JOnAS using as a unix service with standard user priviledge. I have a problem with the tempdir as when I try to upload a file in XWIki I have the following error displayed : "tempdirnotset" So I've added the following line in xwiki.cfg but it doesn't solve my problem : xwiki.upload.tempdir=${java.io.tmpdir}/xwiki In fact, the variable "java.io.tmpdir" is set by JOnAS and is set to "/tmp". So I wonder how can I reuse a java variable to do that ? Regards -- Xavier MOGHRABI - OW2 Consortium Jabber: moghrabi(a)objectweb.org Tel: +33 4 76 61 52 35

I noticed that you are using the eXo Platform. I checked out the web site at http://www.exoplatform.org to get better acquainted with this technology. I was wondering if you could explain the decision to use this technology to build XWiki and what benefits you have realized from this decision? Samer Kanjo
