Dear DH,
Thanks for you quick response. I added the param but now get a new
Exception (see below). The exception still only happens when elements
are removed from the Loop through AJAX, adding all works fine. This
whole volatile concept is a bit fuzzy to me and scanning the source of
the Loop component does not clear things up to me. Do you have any
further pointers?
Cheers,
Joost
