hello,
 I am back..
 - is the tutorial approved ? is it useful to the community ? 
I think you should move it to the draft area for now while we can
correct it. Can you do that?
I'll add a comment on the tutorial page mentioning some draft work and
pointing it there so that people can still find it easily.
  - could it relate to possible improvements to the
core/modules ?
 then please give me directions and I will work on that. 
I'm pretty sure it could. Actually seen the length of your tutorial
I'm 100% percent sure the code needs to be improved to better support
your use case.

 well the DWR tutorial was never completed, and its the next project.
 In fact what I am doing with this tutorial (and hopefully with
 another one talking about DWR and tree view) is the result of my end-
 of-studies internship. The prototype I have done at my internship
 company was rejected by my company's management. But everybody was
 impressed by the work i had done, which was basically porting one
 system to a wiki platform, so using xwiki as a basis and extend it a
 bit. Since my prototype will not be used for further dev by the
 company, I am trying to give something back from my internship - 4
 months of work *have* to produce something useful, and I hope it
 will be my xwiki tutorials.
 I will correct everything in the tut' when i am back from a family
 trip (after the 4th of March, thus). In the meantime, please put my
 tutorial into the draft section and let the dev community decide
 what to do with it (or do whatever you want with it). Just tell me
 what has happened... We can add the functionnality to the core
 (though I will need help from  on how to design the modifications
 that have to be made). It will be a pleasure to work on this for me,
 and to give something back to XWiki. It will not be done overnight,
 though. If I get a job from the 1st of April, then I may not have
 much time in April. Of course during March i will definitely have
 time to devote to XWiki :-). i am up to it, if you want...

 BTW Jean-Vivien you also have another tutorial you had started on
http://dev.xwiki.org/xwiki/bin/view/Drafts/PluginDWR
 which could also be moved at the same location we decide to move
 this new tutorial.

 Jean-Vivien.
 Seems he's really researched the xwiki development capabilities!
 Jean-Vivien, since you seem to have a really good grasp of XWiki I
 hope you'll consider contributing improvements to it and maybe even
 join us as a  committer one day :)
 Thanks
