If the properties of a model are supplied via the YAML map syntax, and have no sub properties (such as "type" or "i18n"), then the Detail subapp of a created app will not show a field for the property.

And, if none of the properties has a subfield - then the entire Detail subapp will not be created in the app.

Since this can be unexpected, we should log an error when such a definition is detected, and ideally report in the problems view of the definition to.

Use the following YAML to reproduce:

contentTypes/bike.yaml

datasource:
  workspace: bikes
  autoCreate: true
model:
  properties:
    title:
    color:

(title and color are supplied via YAML map syntax.)

apps/bikes.yaml

!with-type:bike
label: Bikes
