Hi,
since no values are displayed at all, possibly valuechange-method is
not called. I have put the binding - thanks. How can I check if the
method is called? Sorry, this is my very first JSF application.
Thanks once again.
With regards,
Damar

Hi,
you mean the new list is not re-displayed?
Is the valuechange-method called? You have given a wrong binding (left
out the #{ } ), in this case maybe thats the problem.
regards,
Gerald
