Some *new*  features:

• FCKEditor 2.6.4 SVN, build 21065 added
• Added possibility to switch fill-in-the-blanks answers
• New mp3 player
• New audio recorder in learning path
• Tests : In students results page, set the question comment in red when the student’s answer is wrong. Set in green when the answer id good
• Tests: Added attempts limit
• Allow ZIP export of assignments for teacher and tutor
• Implemented options dropdown to show attachment file and repeated event in calendar

There were some difficulties with these upgrade since Dokeos use it in several tools: Learning Path, Documents, Survey, Exercises, and a long etc.

The BIG problem was to add, update or rewrite the javascript code (fckeditorcode_gecko.js and fckeditorcode_ie.js) that FCKeditor use. You can take a look, is a little bit messy but works. These javascript code was made like that in order to compress the file.

Here some updates:

1. FCKeditor plugins added: FLVMediaPlayer, EmbedMovies, FlashPLayer and the MP3 player create specially for Dokeos.
2. Finally, FCKeditor works with Opera.
3. Creating and editing Flash documents works fine.
4. No more popups! These version of FCKeditor works with DIVs.
5. Is much faster than the old version.

I will update to the last version of FCKeditor 2.6.3 if that fix some problems.

There are also a discussion about the possible changes that the Document tool will have soon.

Yesterday the dev.dokeos.com was updated with these changes,

Here the SVN you can check it out.
