Our current deployment patterns require me to manually write my swagger json output that will be consumed by the Swagger-based UI in use at my company. I'd like the json I'm writing to provide 'default' values to populate the Swagger UI for all input fields, including the body input parameter. My body parameter is a referenced object as seen below. How do I define the returned swagger JSON to auto populate the body portion of the request when the "Try this operation" is clicked?
An example Swagger spec that has no default/example data populated in the Swagger UI is below.

I have been testing this json at http://editor.swagger.io/#/ by clicking File->Paste JSON.... I then click "Try this operation", scroll down and observe that the values of my body parameter are not populated - that's what I'd like to change.
Thanks in advance for any suggestions.
To have example values, you just have to add an "example" property where needed:
exampleDefinition:
type: object
description: Request details for Example Definition
properties:
action:
type: string
description: Specifies the action to be taken
example: An action value
applyToBase:
type: string
description: >-
A boolean value that defines the behaviour of the request against the base
example: An apply to base value
addOnIDs:
type: string
description: The identifiers for the add-ons
example: an ID
Unfortunately the online editor don't propose them but SwaggerUI does:
To populate default values to be used when clicking on the "Try this operation" you just need to add the 'default' parameter for the properties in the definition. This works in the online editor:
