Thanks very much for the help on maven build. *About making a object from Blog.BlogPostClass and toXML()* A blog object is having properties of type other xobject classes. So to make the things general can we do a stripped down replication or make something similer to the java classes in com.xpn.xwiki.objects and its 2 sub packages .classes, .meta . We can make a document object representing a page and put a Blog.BlogPostClass object to its list of objects.We can convert them to simple xml model directly.If we want to post blog object we can post the Blog object.If the page does not exist we can put the page by getting the xml from the Document object. Then the things will be general not only for blog client app. Also we can have Type checking when we don't directly manipulate simplexml objects. i.e. XStringClass will define the attributes for it and likewise. I don't have a good idea on the above packages and classes. Specially why there are three classes for each XType ex: StringProperty, StringClass, StringMeta. It will be helpful if you can give an explanation. My draft solution is to do some simple thing as, XObject |____ XBoolean XObject |____XString XString has methods, toEmbedXML gives a <property><attribute/>...</property> string/ simpleXML objects toXML gives <object><id><ClassName>.......</object> for the same thing. Also XObject |_____ XBlogPost for(BlogPostClass and other 2 Meta,Property classes) I don't yet have a clear idea on this. May be I am wrong on this. Can you give me your idea here as well. How to approach the problem and what should the design be like? Thanks. Best Regards Sasinda.

[xwiki-devs] Groovy Console Extension compatible with XWiki 3.5?
by Niels Mayer 16 Jun '12

Is there a version of the Groovy Console ( http://extensions.xwiki.org/xwiki/bin/view/Extension/Groovy+Console+Applica… ) that is compatible with XWiki 3.5? When I try to run it, I see missing icons ( referencing old skins, which I fixed), but now get the following JavaScript errors after attempting to execute my Groovy code: Uncaught ReferenceError: CodeMirror is not defined var editor = CodeMirror.fromTextArea('script', { And "Uncaught TypeError: Cannot call method 'getCode' of undefined" var ajx = new Ajax.Request("$scriptDoc.getURL('save')" , { parameters: {"XWiki.ConsoleScriptClass_${scriptObj.number}_code":editor.getCode(), "ajax":"1"}, onComplete:function(transport){ $('saveLoading').addClassName("hidden"); $('saveStatus').removeClassName("hidden"); $('saveStatus').innerHTML = "Saved !"; var foo = new Effect.Highlight('saveStatus'); setTimeout(function(){ $('saveStatus').innerHTML = ""; $('saveStatus').addClassName("hidden"); }, 5000); } I guess I could keep plugging away and trying to fix this, but was wondering whether there's a newer version of the Groovy Console compatible w/ XWiki 3.5 and beyond, or is there some simple fix to the problems outlined above? Seems like this has been noted as a problem previously: http://lists.xwiki.org/pipermail/users/2011-October/020745.html I attempted installing 'SyntaxHighlighting' (says its "CodeMirror based syntax highlighting ...") and noticed it now adds new error at startup in the GroovyConsole: Uncaught TypeError: Object function a(f,g){if(g.dumbTabs){g.tabMode="spaces"}else{if(g.normalTab) Suggesting problems w/ this extension as well. I do note that my existing scripts now have pretty syntax highlighting... so it is working. Unfortunately, it also forces the wiki-code editor to appear below the wysiwyg and makes the wysiwyg area too small. So I uninstalled it and my Wysiwyg now works as before.... Any way of getting Groovy Console functionality working? Seems like a great way to work with cloud-based XWiki installs, such as mine... Thanks, -- Niels http://www.nielsmayer.com

[xwiki-devs] [Ideas] Some thoughts about Extension Manager's future
by Ecaterina Moraru (Valica) 15 Jun '12

15 Jun '12

Hi, I want to list some ideas about Extension Manager that come to my mind. I'm sure others thought about them already or will find the time to make some other suggestions: 1) Filtering core extensions Would be nice to be able to view preinstalled applications with EM. Right now everything that comes preinstalled is found inside 'Core extensions'. There are a lot of technical extensions, but there are also some extensions that could be of general knowledge. For example it would be nice to see what functionality a default wiki has in terms of applications and macros (even nicer if we think about future flavored packages). This would allow the administrator to quickly scan and customize the tools at his disposal. Maybe it would be interesting to have some filtering functionality. This way I could filter for applications and see that I have preinstalled 'Activity Stream', 'Annotations', 'Search', 'WYSIWYG', 'Message Stream', etc. and if I filter for macros I could get 'Chart macro', 'Box macro', 'Display macro', 'Message macro', etc. 2) Enable/Disable applications from inside EM Another idea is for the EM to sustain enable/disable actions for installed/core applications/macros. Right now applications like 'Annotations', 'Search Suggest', 'Message Stream', even 'OpenOffice Server' have special settings that permit to enable ('activate') them. This functionality could be covered by the EM and not display anymore special administration sections for each applications. 3) Integrate application configuration inside EM If EM will manage installed applications and would also allow the enabling/disabling part, than is normal that the application configuration should be made also from inside the EM and not as a separate Administration component. Although all things in XWiki are extensions and components, we would need to get along what the lightest version of xwiki would contain (in terms of functionality and not components). For this default functionalities (Users, Rights, Localization, Presentation, Import/Export, etc.) the Administration sections would be still used, since they could be considered core elements and not something that can be disabled or uninstalled. Maybe all the thoughts I am writing here could also be solved if we rewrite some functionality like 'Activity Stream', 'Annotations', some macros, etc. and not display them anymore as 'Core Extensions' but rather as 'Installed Extensions'. Thanks, Caty

[xwiki-devs] xredirect parameter after an upload action
by Paul Libbrecht 14 Jun '12

14 Jun '12

Hello developers, I seem to see a regression whereby a POST to an /xwiki/bin/upload/ request no more uses the xredirect parameter and simply redirects to the page. Is this a known change? Is it supposed to have been working being undocumented and can try to find a fix? Or should I simply try to adjust the client (tremble tremble). thanks in advance Paul

[xwiki-devs] Extension management - Questions
by Gianluca Sabena 14 Jun '12

14 Jun '12

Dear all, some notes about my recent upgrade from 3.5 wiki farm to a 4.0 -- Sysem -- * Xwiki 4.0 farm (the old way, independent farm) * Jetty package that you provided xwiki-manaer-mysql-4.0 * 4 wikis (2 active, one template and the manager) * File attachments on filesystem -- Question -- 1) After I have upgraded from xem 3.5 to xem 4.0 all previously installed extensions have been removed from XEM control panel (but extension pages are still present) - minor bug, I have solved it reinstalling all extensions. 2) Since XEM 3.5 xwiki-manager can setup two different kind of multiple wikis: a) workspaces b) the old way wikifarm. - What is exactly the difference between that two? - XEM home page suggests to create workspaces and the old wikifarm is placed in a sub page, this create some confusion. I would prefer to have both options on the home page with some notes that explain differences. Personally I use the wiki farm (independent wikis). 3) In wikifarm (independent wikis) management of extensions is not clear. - If I install an extension from XEM it is installed in all sub-wikis, but if I remove it, it is removed only from XEM and not from sub-wikis (pages are still present but extension disappear form sub-wikis control panel, so it is impossible to completely remove them) - If I install an extension in sub-wiki, it is listed in XEM, but if I select it I see many errors. -- Bugs -- - One of the two wiki is constantly loosing web preferences settings (skins and localization template), no error in file log, really annoying and hard to debug. - Since webpreferences settings are lost, it is impossible to know what extensions were installed -- Workaround -- - Is it possible to have multiple wiki (completely independent) without using Xem? -- My proposal -- - If an extension is installed in XEM it can be removed only from XEM and this remove the extension form all sub-wikis (we could delete pages and send them in the recycler bin for better security) - If an extension is installed in sub-wikis it is only listed in the relative control panel of that wiki Thank you, Gianluca

I wouldn't call it a bug, because if we do so, then we can argue that it's a bug that has been there for at least one major cycle, and that macros.vm is still not stable according to http://jira.xwiki.org/browse/XWIKI-6062 so we might still have "bugs" about it (and that is for about 2.5 major cycles, which is a bit too much from my point of view). What I would say about this is that apparently we don't know / have a convention about how should the macros in macros.vm be used: with syntax interpreted or not, in an html macro or not. This is where the confusion comes from: while the old panelheader macro _needed_ html macro (potentially with syntax activated), the current one needs _only wiki syntax_ (potentially in an html macro). There is a context which satisfies both (html macro with wiki syntax activated) but it was not documented anywhere, I'm not even sure it is _the rule_ for macros in macros.vm, so people used "what it worked", in this case a plain simple html macro whose wiki parameter defaults to false. The wysiwyg macros in macros.vm, for example, I would say they need to be called in a html macro with syntax switched off, but it's just a guess, looking at the code. I think we need to: 1/ make a decision about what is API from macros.vm 2/ make a decision about what _was_ API from macros.vm and keep it working as it used to 3/ document how an API macro should be used, either by having a rule or by at least writing in its own documentation in macros.vm what context it expects (note that even if we document it, if we cannot enforce it, chances are that people will use "what it works"...) To me, all these above are unclear and until they are, from how it feels to me, it's very hard to call something a bug or a backwards compatibility break.
