Thanks for the answer, and sorry for the duplicated mails (our mail
server has problems),
This solution works well, but I really can't see why the behaviour is
different : the actionlink is the same in the 2 situations explained

Or does it simply mean that we should not use persisting attributes in
components when there is a loop ?
Kind regards,
Ahingsaka
