Subject: Dynamic Column Datatable - Example
Hi,
I think what I need to do is fairly common. I have a number of
checkboxes that users can select to determine which columns they want
displayed in a datatable.
I've been searching for an example of a dynamic datatable and haven't
been able to find one. I've seen references to a solution in 2008 mail
archives that suggest it might be implemented in 1.4
(http://www.mail-archive.com/users@wicket.apache.org/msg10528.html).
Can anyone confirm that it has been or not? In either case, is there an
example that someone can point me to?
Thanks in advance!
Shelli
