For example, to define a custom formatter:
val signedIntFormat = new Formatter[Int] { def bind(key: String, data: Map[String, String]) = { stringFormat.bind(key, data).right.flatMap { value => scala.util.control.Exception.allCatch[Int] .either(java.lang.Integer.parseInt(value)) .left.map(e => Seq(FormError(key, "error.signedNumber", Nil))) } } def unbind(key: String, value: Long) = Map( key -> ((if (value<0) "-" else "+") + value) ) }
