Why is the message "Unable to resolve method" applicable with this caption: "Missing arguments"?
I have a fairly extensive form defined as:
case class EditDetail(token: String,
placeId: Long,
// accessibility
privateParking: Option[Boolean],
privateParkingType: Option[Int], // 0: internal, 1: external, 3: street
bikeParking: Option[Boolean],
valetService: Option[Boolean],
wheelChairAccess: Option[Boolean],
// facilities
cashOnly: Option[Boolean],
paymentMeans: Option[List[String]], // comma separated Option[List[String]]s

reservationMethods: Option[List[String]], // <-- the problem area
reservationUrl: Option[String],
groupSizeMin: Option[Int],
groupSizeMax: Option[Int],
// delivery & takeaway
delivery: Option[Boolean],
minDeliveryAmt: Option[BigDecimal],
takeAway: Option[Boolean],
// atomosphere

viewPoint: Option[Boolean],

sportsFeatured: Option[List[String]]*/) {
var place: Place = _
var user: User = _
}
var editDetailForm = Form(
mapping(
"token" -> nonEmptyText,
"place_id" -> longNumber,
/*ACCESSIBILITY*/
"private_parking" -> optional(boolean),
"private_parking_type" -> optional(number(0, 3)),
"bike_parking" -> optional(boolean),
"valet_service" -> optional(boolean),
"wheelchair_access" -> optional(boolean),
/*FACILITIES*/
"cash_only" -> optional(boolean),
"payment_means" -> optional(list(text)),
"wifi" -> optional(number(0, 2)),
"smoking" -> optional(boolean),
"aircon" -> optional(boolean),
// /*DINING OPTIONS*/
"dietary_restrictions" -> optional(list(text)),
"meals_served" -> optional(list(text)),
"alcohol_choice" -> optional(list(text)),
"outdoor_seating" -> optional(boolean),
"catering" -> optional(boolean),
/*RESERVATIONS*/
"accepts_reservations" -> optional(number)
// "reservation_methods" -> optional(list(text)) // <-- problem area
// "reservation_url" -> optional(text),
// "group_size_min" -> optional(number(0)),
// "group_size_max" -> optional(number(0)),
// /*DELIVERY & TAKEAWAY*/
// "delivery" -> optional(boolean),
// "min_delivery_amount" -> optional(bigDecimal),
// "takeaway" -> optional(boolean),
// /*ATMOSPHERE*/
// "music_type" -> optional(list(text)),
// "ambiance" -> optional(list(text)),
// "attire" -> optional(list(text)),
// "surrounding" -> optional(list(text)),
// "view_point" -> optional(boolean),
// "good_for_kids" -> optional(boolean),
// "tv" -> optional(boolean),
// "sports_featured" -> optional(list(text))
)(EditDetail.apply)(EditDetail.unapply))
If you see the code above and see the line marked <-- problem area
, if I uncomment this line in EditDetail
and in editDetailForm
, I get this:
Cannot resolve method with such signature: Missing arguments
Why?

This is because you have exceeded the maximum number of fields for one tuple (18), this is what the Play doc says :
Note. The maximum number of fields for one tuple or display is 18 posts per form processing. If you have more than 18 fields in your form, you should break up your forms using lists or nested values.
