When a form is submitted and for example a date field contains letters, the conversion in the respective field fails silently.
Currently there is no built-in way to inform the user of that event.
The normal validation occurs after the (un)successful conversion.
A "work-around" trait was suggested [[url:http://groups.google.com/group/liftweb/browse_thread/thread/1b8b50be264b5848#|here]] as well as the desire for an feature enhancement ticket.
Not going to get this into 2.2
