Release Notes for XWiki Enterprise 1.8.4

The focus on 1.8 branch was on making the new rendering architecture and the new GWT based WYSIWYG able to fully replace the "old" rendering and TinyMCE based WYSIWYG. This version introduce conditional loading of JavaScript and StyleSheet in order for pages to load faster, sending to the browser only the files it needs to display the requested pages. This might break existing applications developed on top of XWiki that relied on such JavaScript and CSS files being present all the time. See Applications migration section for more details

Common Migration notes

  • In order to benefit from improvements listed above, import the default wiki XAR 
  • Add xwiki.store.migration=1 so that XWiki will attempt to automatically migrate your current database to the new schema.

Applications migration

XE 1.8M2 has introduced conditional loading of JavaScript and StyleSheet files in order for pages to load faster, sending to the browser only the files it needs to display the requested pages. This might break existing applications developed on top of XWiki that relied on such JavaScript and CSS files being present all the time. Concerned files and libraries are the following:

  • scriptaculous files
  • accordions files
  • chart wizard files
  • usersandgroups.js and usersandgroups.css
  • livetable.js and livetable.css
  • lightbox.js
  • tablefilterNsort.js and table.css
  • fullscreenEdit.js and fullscreenEdit.css

Applications that relies on one or several of these libraries, need to explicitly make them request the desired files using the Skin Extension plugin. For example, if your application needs the live-table feature (the dynamic AJAX grid), add the following lines to the code page that requires it:

$xwiki.jsfx.use('js/xwiki/table/livetable.js') ## Inject livetable.js <script> tag in the header
$xwiki.ssfx.use('js/xwiki/table/livetable.css') ## Inject livetable.css <link> tag in the header
