[xwiki-users] Renaming items in applications within a minute
by Moritz Hesse (EA GmbH) 17 Apr '12

17 Apr '12

How can I rename items in my applications? I can only modify all the values of my specified fields but not the name or title of the items. Thx + kind regards, Moritz By the way: What is the difference between the page title and the page name? They appear to be the same in my applications.

See http://www.xwiki.org/xwiki/bin/view/FAQ/HowToSolveAJavaHeapMemoryError If you have a big .xar to import, you may have to: * export your source wiki space-by-space (see http://extensions.xwiki.org/xwiki/bin/view/Extension/Large+Export+By+Space+…) * split your .xar manually (unzip/edit packages.xml/zip part of dirs - risky if you have weird page names) * use some BIG machine (I've used EC2 High-Memory instance) Cheers, R.

Hi, after upgrading to 3.5 the Admin lost its ability to change the WebPreferences like "showcomment". In the "Administration: Page Elements" - Section only a Save Button is shown, but the elements are not editable. Any suggestions? Thanks, Stefan.

[xwiki-users] Registration Form Validation
by Nicklin, Andrew 16 Apr '12

16 Apr '12

Hi - I'm trying to add a checkbox to the account registration form (XWiki Enterprise 3.5). I can add the field so it renders on the form: ## ## The terms of service agreement, checking. #set($field = {'name' : 'tos_agree', 'label' : '<hr />I have read and agree to the above terms of use.', 'params': { 'type' : 'checkbox' } }) #set($discard = $fields.add($field)) However, I would like to validate that the checkbox has been checked before allowing the registration to take place. I do not need to store the checkbox value in the user objects. I've tried several validation variations based upon the examples in the registration code and other places, but nothing has worked, so I thought I would turn to the community for some help. Thanks in advance! -Andrew City of New York

[xwiki-users] Why does XE3.5's annotation feature kill embedded player in YouTubeCaptioner macro?
by Niels Mayer 16 Apr '12

16 Apr '12

I'm playing around with dynamically extracting YouTube's captions into a XWiki document via my macro http://m.nielsmayer.com/bin/view/Macros/YouTubeCaptioner Examples: http://m.nielsmayer.com/bin/view/Sandbox/Google+Talk%3A+Mindfulness+with+Jo… http://m.nielsmayer.com/bin/view/Sandbox/XWiki+-+the+french+open+source+cou… http://m.nielsmayer.com/bin/view/Macros/YouTubeCaptioner_Test (Steve Jobs Stanford Commencement Address) An interesting possibility entailed by the above approach is that XWiki's annotation system can be used to annotate the extracted deep-links to the video. Unfortunately, in the first two examples, when annotations are turned on, the video display disappears. Any suggestions on having both annotations and YouTube's video player on the same document at the same time? Seems as if the page gets redisplayed when annotations get turned on, but the YouTube-suggested "hook" to create the player out of JavaScript doesn't get called. I changed YouTube's code to load the YouTube javascript out of XWiki as suggested by http://platform.xwiki.org/xwiki/bin/view/DevGuide/JavaScriptAPI#HDOMEvents2…, but it didn't help. Here's my code for the macro YouTubeCaptioner: --------------------------------- {{velocity}} {{html}} <div id="ytplayer"></div> <script type="text/javascript"> // Load the IFrame Player API code asynchronously. If you load the iframe // the normal way ( // http://developers.google.com/youtube/player_parameters#Manual_IFrame_Embeds) // you get cross-domain-error attempting to retrieve the YouTube player object // in JavaScript from parent frame that is in different domain. Some browsers // seem stricter than others in enforcing this potential security exploit, but // Chrome will definitely prevent it. Instead, must create the player in // JavaScript ( // http://developers.google.com/youtube/player_parameters#IFrame_Player_API ) // so that the caption links in the Groovy section below can reference the // YouTube embedded player as 'player' // // NPM: augmented original YouTube suggested init with suggestion from // http://platform.xwiki.org/xwiki/bin/view/DevGuide/JavaScriptAPI#HDOMEvents2… // in the hopes that annotations will display at same time as video player. function youtube_init() { var tag = document.createElement('script'); tag.src = "https://www.youtube.com/player_api"; var firstScriptTag = document.getElementsByTagName('script')[0]; firstScriptTag.parentNode.insertBefore(tag, firstScriptTag); } (XWiki && XWiki.domIsLoaded && init()) || document.observe("xwiki:dom:loaded", youtube_init); // Replace the 'ytplayer' element with an <iframe> and // YouTube player after the API code downloads. var player; function onYouTubePlayerAPIReady() { player = new YT.Player('ytplayer', { height: '390', width: '90%', videoId: '${xcontext.macro.params.videoId}', //pass in videoID parameter of macro cc: '1' //force closed captions display }); } </script> {{/html}} ## ## Make Groovy-generated HTML Table filterable and sortable in browser via JavaScript ## http://platform.xwiki.org/xwiki/bin/view/Main/XWikiSyntax#HTables ## $xwiki.ssfx.use("js/xwiki/table/table.css") $xwiki.jsfx.use("js/xwiki/table/tablefilterNsort.js", true) {{/velocity}} {{groovy}} import org.apache.commons.lang.StringEscapeUtils; def url = ("http://www.youtube.com/api/timedtext?v=" + xcontext.macro.params.videoId //pass in videoID parameter of macro + (xcontext.macro.params.ttOptions ? xcontext.macro.params.ttOptions : "") + "&format=1&lang=en" ).toURL().text; def root = new XmlSlurper().parseText(url); println "(% class='grid filterable doOddEven' id='tableid' %)"; println "|=Caption|=Start Time|=Duration"; root.children().each() { def dec = it.text().replace("\n", " ").replace(">>", "\n####"); //remove linebreaks embedded in captions dec = StringEscapeUtils.unescapeXml(dec); println "|[[{{{${dec}}}}>>path:javascript:player.seekTo(${it.attributes().start}, true);]]|${it.attributes().start}|${it.attributes().dur}"; } {{/groovy}} --------------------------------- Also, I've noticed that when selecting items in a table for annotation, you have to select the entire table-row, in order for the selection to be displayed successfully. Is this a general feature of XWiki's annotations or a specific problem caused by my examples, which annotate dynamically generated content. -- Niels http://m.nielsmayer.com <-- my new http://Jelastic.com cloud-hosted XWiki

[xwiki-users] Force page breaks for Printouts and repeat table captions
by Sebastian Fix 16 Apr '12

16 Apr '12

Hi All, 2 questions regarding the printing of pages: 1. is it possible to "force" a page break for printouts of Wiki-pages to make sure, that a certain amount of information is on 1 page? 2. is it possible to repeat part of a wiki-table (caption)automatically on each page? I need to use those as a middle step before moving to xwiki completely regarding Quality-related documents.. Thanks, Sebastian -- NEU: FreePhone 3-fach-Flat mit kostenlosem Smartphone!

[xwiki-users] no empty values on 'selectedColumn' livetable
by Joris Dirks 16 Apr '12

16 Apr '12

I'm wondering if I ran into a bug or I just don't understand the methods very well for Livetable macro. When I order with 'selectedColumn', all pages without a value for that property disappear from the results. See the example below, but I've tried various types of properties. {{velocity}} #set($columns = ["doc.name", "_Deadline"]) #set($options = { "className":"App.DemoClass", "selectedColumn": "_Deadline" }) #livetable("bydeadline" $columns $columnsProperties $options) {{/velocity}} Thanks for your ideas!

[xwiki-users] 4.0 RC1 Feedback: Hidden Documents
by Richard Hierlmeier 13 Apr '12

13 Apr '12

I tested the new hidden documents feature in xwiki 4.0RC1. I do not see any impact of the "Hidden document" flag. I can see hidden documents as unregistered user and also as user with user preferences "Display hidden documents" set to "No". Changes on the hidden document are visible in the activity stream for such users. Is it working?
