Hi Thnx,
I think the validation is important as mostly a web app that I would
build is forms, validation, database.
I generally use PHP Zend Framework due to the ability to outsource
some work to reduce my workload as PHP programmers are cheap.
You could take some ideas from its validation and form decorators.
However I can tell that Liftweb will increase my productivity much
more so maybe it won't be necessary to get outsourced work for this
part of website development.
Thanks, Philip
