Hi Gerhard,

Yes, that is more or less what I ended up with, but for efficiency I only
update the lists in the backing bean when one of the triggers which the list
content depends on changes.  I use a4j:support to fire the trigger to update
the list and the a4j:support rendered attribute to cause the associated
lists to be re-fetched if they are on the same page.

However, having an attribute similar to "rendered" on SelectItem would have
simplified things and been quite elegant.

Regards

Martin
