Re: [xwiki-devs] Hashmap vs. Objects (Miscellaneous Questions)
by Kamna Jain 05 May '08

On the same note, I also have the following questions: The answers will help implement whichever option we choose: 1) Is there a limit on the number of members that can belong to a group? 2) How can I create a "global" hashmap (xwiki.getHashMap()) that can be referenced anywhere (any page/space) to retrieve values based on keys? 3) Can I use the $context to add some more values(needed for our project) to the hashtable? 4) I came across the following code snippet int he Wiki editor of the PanelWizard: #set($categoryMap = $xwiki.getHashMap()) #foreach($category in $categoryList) $!categoryMap.put($category, $xwiki.getArrayList()) #end I do not understand the use of "!" in the put() method. what do we achieve with this! Thanks for all help!

[xwiki-devs] edit menu options question
by Jeff Gerbracht 02 May '08

02 May '08

When I'm logged in as a user with all global privilages, and I'm on a wiki page, the "edit" menu doesn't have any sub-menu items. However, when I log in as superadmin, I see sub-menu items such as "wiki", "WYSIWYG", "Inline form" etc. Is there a way to set up a user other than superadmin with this?? Thanks, Jeff

[xwiki-devs] About the new SkinExtensions plugin
by Jean-Vincent Drean 01 May '08

01 May '08

Hi XWikiers There are open question about the new skinx plugin, I'd like to discuss about the first one : http://dev.xwiki.org/xwiki/bin/view/Design/SkinExtensions#HUsage "Should $xwiki.jsx.useFile("filename.js") work for files located on the disk? This allows the same pull process to be used with files located in the skin, without requiring SX documents and objects. I'd say yes. Then, what should the URL look like? /xwiki/bin/jsx/skins/albatross/somestyle.css is OK?" We definitely need this to be able to load some libraries condditionaly, for example usersandgroups.js or lightbox.js. I don't see the need for some special URLs, would it be a problem that useFile() adds the result of a xwiki.getSkinFile() to the header ? Thanks, -- Jean-Vincent Drean

[xwiki-devs] XWiki.TagClass in Xwiki 1.3
by Kamna Jain 01 May '08

01 May '08

Devs, How is the TagClass used? Does a page contain one object of this class for every Tag that is added to the page/document. or Do, all the tags belong to the same "tags" field of one object. I tried adding 2 tags (separated by a | ) and then used rthe following code, it does not seem to work. Please guide: #set($assetDoc = $xwiki.getDocument($asset)) #set($tagObject=$assetDoc.getObject("XWiki.TagClass")) #set($tags = $tagObject.get("tags")) #set($tagList = $tags.split("|")) or #set($tagList = $tags.toString().split("|")) (even getName() does not work) #foreach ($tag in $tagList) #if($tag == "XYZ") ( #if($tag.equals("XYZ")) also does not work but when I had only one tag in the tags field, I just used : #if( $tagObject.get("tags") == "XYZ") and this worked.... Please help - one tag per object or multiple tags per object? Thanks

I don't know why this happened (it can a lot of reasons) but the way to solve it for now is just to restart the JVM (i.e. the servlet container). Thanks -Vincent

[xwiki-devs] Reviewing XE 1.4 roadmap vs what we did
by Vincent Massol 01 May '08

01 May '08

Hi, I'd like that we review our objectives for 1.4 vs what we've done: * Bug fixes o Go from 240 in JIRA for Core down to 180 on XE 1.4 release date Right now the bug count is at 227. Even though it's lower than 240 it's still a far cry from the 180 target... * Better performance o Run XE with a profiler and find bottlenecks Not done o Reduce number of database calls Not done o Improved page loading (JV) Not done o Make Stats usable on xwiki.org (ThomasM) Done! * More automated tests o More selenium tests We can consider this done although we always need more. We need to continue adding and even spending some time just adding tests even if we don't have code at all. o Add tests on Tomcat 6.x as part of the CI build Not done o Add tests on Windows and with IE6 and IE7 as part of the CI build Not done Conclusions: ========== * We're not too good. I think this is principally due to me, since I focused on the new rendering component and have delegated XE day to day management/coaching to JV. Thus JV has not been able to work on the performance improvements as planned. We really need to get that going in 1.5 now. * We have 1 more week to fix as many bugs as possible. WDYT? Thanks -Vincent

[xwiki-devs] Roadmap for XE 1.5
by Vincent Massol 01 May '08

01 May '08

Hi, I've started the page at http://enterprise.xwiki.org/xwiki/bin/view/Main/Roadmap but let's discuss it here first. So what are the tasks we want to solve for 1.5. Here's my take: * More bug fixes * Better performance o Run XE with a profiler and find bottlenecks o Reduce number of database calls o Improved page loading * More automated tests o More selenium tests o Add tests on Tomcat 6.x as part of the CI build o Add tests on Windows and with IE6 and IE7 as part of the CI build * Overhaul of the Administration So basically more stability and more usability. In term of dates, I think 2 milestones followed by a RC works pretty well. In total that's about 3 weeks for each milestone and then 1 week for each RC. If we imagine we need 2, then that's 8 weeks, i.e. 2 months, which sounds good to me. WDYT? I'll let JV propose precise dates. Thanks -Vincent
