[Laszlo-user] dataset updated, replicated <textlistitem>s are not

[Daniel Salama]

You may want to check:

http://www.laszlosystems.com/lps-3.3/docs/guide/ 
databinding.html#d0e21901

Which is basically Section 9.2 of Chapter 34 in the Software  
Engineer's Guide to Developing OpenLaszlo Applications.

It's not 100% what you are doing what you should be able to infer  
from the example how to solve your problem.
