[Laszlo-user] Laszlo Newbie Question: updateDate() to dataset (.xml)

[Benjamin Shine]

The OpenLaszlo server will not write data back to the xml file on  
disk; that's outside the scope of the problem OL is trying to solve.  
OpenLaszlo is primarily a *presentation* layer; you have to go  
elsewhere for the middle-and-inner-ware of your application stack:  
php, rails, a j2ee servlet, etc.

Check out Laszlo on Rails; rails gives you delicious persistent  
server-side databases and operations, and Laszlo gives you the sweet  
application UI framework.
