Is is just one specific field that fails? Perhaps there's something
odd about the field's name (the way naming a Form field "submit" can
cause grief ... something Tapestry won't even try to do now).
This code has changed in 5.3 recently, to defer the lookup until an
error actually needs to be displayed.
