lift

Hi, I have browsed lift's MegaProtoUser and encountered this construction: ??("Last Name"). Can anyone explain, what that means? Also, I didn't find a way how to add a custom field into MegaProtoUser. The maven's lift's basic archetype defines another field, but it never shows anywhere. (Version 1.0)
Thanks for answering

DocBook sources of "Starting with Lift"

By the looks of it, I wouldn't be surprised if "Starting with Lift" has been created from DocBook. I looked in Lift's Git repositories, but I haven't been able to find the source DocBook documents. So, is it really based on DocBook? And if it is, is it available from some public repository? >>> More
using REST webservices as a datasource for Lift ?

Is there a way to use a webservice (REST in this case) as the data source for a Lift application? I can find a number of tutorials/examples of using Lift to provide the REST API, but in my case the data is hosted elsewhere and exported as a REST webservice. Pointers to doc are greatly appreciated… >>> More
