PHP - Get correct objects in array

I have troubles getting the correct objects in array with the PHP codegen.

The yaml looks like this (the complete yaml can be seen here:

/location/idContract/{idContract}:
    get:
      tags:
        - location
      operationId: getLocation
      parameters:
        - name: idContract
          in: path
          required: true
          schema:
            $ref: '#/components/schemas/IdContract'
      responses:
        '200':
          content:
            application/json:
              schema:
                $ref: '#/components/schemas/LocationList'
...
...
Components:
    LocationList:
      type: array
      items:
        $ref: '#/components/schemas/LocationItem'

    LocationItem:
      type: object
      additionalProperties: false
      properties:
        locationNumber:
          $ref: '#/components/schemas/LocationNumber'
        location:
          $ref: '#/components/schemas/Location'

I'd expect to get properly typed array of LocationItems in the LocationList object and some setters / getters to get the values, but in the generated PHP model there's not anything like that. The LocationList object that is returned contains only an empty container property.

Any idea how to fix this?

Bellow is the generated model.

Start with the PHP codegen handling for the LocationList array schema and compare the generated LocationList model with the LocationItem reference in the supplied YAML. Confirm how array responses are deserialized; done means the generated model represents and returns the LocationItem objects instead of only an empty container.
