translation.field_type: A message field is a type a wording can't hold

A message field is a type a wording can't hold.

Area 10, Configuration; not declinable; the next step is usually the agent's.

A message's fields are the placeholders of its wording: text, numbers, amounts of money, a plural count, or an enum that picks the wording. A moment is formatted in code and passed in as PresentationText.

example

/// When a parcel left, on the tracking page.type LeftAt = Message {    when: Instant}

jadpo checkcheck failed: 1 error, 2 files

error LeftAt.when is typed Instant, which a wording can't write

--> domains/shipping/translations/left_at.jadpo:3:5

  |3 |     when: Instant  |     ^^^^ not text, a number, money, a percentage or a choice

reason: A message's fields are the placeholders of its wording, and a placeholder is text (Text, PresentationText), a number (Int, Decimal), an amount of money (Money, written {field, number, currency}), a percentage (Percentage, written {field, number, percent}) or a plural count (PluralCount), or a type built on one of them; one enum field picks which wording is written. Dates and times are formatted in code, with text.format, and passed in as PresentationText.
next: Make when a PresentationText and format the value where the message is called (agent)

A failure's client: fields are placeholders too, filled by the client app, which formats a date, a time, a number or a duration for its own language. A choice has no such format.

example

use shipping/types { HoldReason }type ParcelHeld = Failure {    kind: FailureKind.rejected    client: {        reason: HoldReason    }}

jadpo checkcheck failed: 1 error, 4 files

error ParcelHeld.reason is typed HoldReason, which a client can't write into a wording

--> domains/shipping/failures/parcel_held.jadpo:6:9

  |6 |         reason: HoldReason  |         ^^^^^^ not text, a number, a date, a time or a duration

reason: A failure's client: fields are the placeholders of its wording, and the client app fills each one: text as it is, and a number, a date, a time or a duration formatted for its own language. A choice, an object, a list or an optional value has no such format.
next: Make reason text, or send the text in a PresentationText field (agent)
