I think that you'll need to provide your own _toForm method on the field.
Fortunately, it's a pretty trivial method (from MappedField.scala):
1. /**
2.* Create an input field for the item
3.*/
4. override def _toForm: Box[NodeSeq] =
5. S.fmapFunc({s: List[String] =
Ah, MappedFields know how to make themselves to form fields. Very nice!
Next question: Now I can enter some characters into the MappedInt field and
will get a 0 (zero) on form submission. But that is not what I want. I would
like to show a validation message (FieldError). Any chances to hook into
