Title: Do not call valueBox at lift record Field.setBox

at Field.scala
at method setBox

val same = (oldValue, valueBox) match {
case (Full(ov), Full(nv)) => ov == nv
case (a, b) => a == b
}

should be changed to

val same = (oldValue, data) match {
case (Full(ov), Full(nv)) => ov == nv
case (a, b) => a == b
}
