[xwiki-users] Links to pages in 1.0 syntax don't look good

Hi all, Our XWiki instance has been upgraded to a 2.0. We are still using 1.0 syntax and we can see some strange behaviour. If you look at this page http://www.parisjug.org/xwiki/bin/view/Speaker/ all the titles (the name of the speakers) look ok. But if you click to a specific speaker ( http://www.parisjug.org/xwiki/bin/view/Speaker/MagninLaurent), you can see that the title is [Laurent Magnin>Speaker.MagninLaurent] instead of just Laurent Magnin. This doesn't happen to all the pages (ex. http://www.parisjug.org/xwiki/bin/view/Speaker/MartignoleNicolas). All these pages are in XWiki syntaxe 1.0 and all have the same syntax : 1 [Laurent Magnin>Speaker.MagninLaurent] Do you know what that could be ? Thanks, Antonio
