Important bug fixes

  • Add support for Velocity and HTML as well as many bug fixes and improvements in the XWiki syntax converter to convert from 1.0 syntax to 2.0 syntax.

Known issues

If you're on Mac and want to run XWiki Enterprise on the JDK 1.5 but have JDK 1.6 installed then the Groovy macro in the new rendering won't work fine and you'll get some exceptions. This is because of a Mac problem: When Java 1.6.0 is installed in OSX 10.5 it overwrites /System/Library/Java/Extensions/AppleScriptEngine.jar with a 1.6 specific one. When the ScriptEngineManager gets initialized if finds it and tries to use it. However it only works on JDK 1.6. Moving both AppleScriptEngine.jar and libAppleScriptEngine.jnilib somewhere else fixes the problem.

Migration Notes

Data migration

If you're running in a multiwiki setup you'll also need to define the property to your xwiki.cfg file or explicitly name all databases to be migrated as in,db2,....

You may also want to import the default wiki XAR in order to benefit from improvements listed above.

Always make sure you compare your xwiki.cfg file with the newest version since some configuration parameters were added. Of note, you should add so that XWiki will attempt to automatically migrate your current database to the new schema. Make sure you backup your Database before doing anything.

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

If you have applications that relies on one or several of these libraries, you will 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
