additionalProperties is not respected unless it is an object

[saml]

If my schema specifies:

{
  "properties": {
    "any-object": {
         "type": "object",
         "properties": {},
         "required": true,
         "additionalProperties": true
     }
   }
}

The following data is considered invalid:

{"any-object": {"a":1}}

Probably due to the following line (current master):

swagger-jack/src/validator.coffee

Line 59 in 9080379

additionalProperties: if _.isObject(model.additionalProperties) then model.additionalProperties else false

convertModel = (models, model, _stack) ->
  result = {
    properties: {}
    additionalProperties: if _.isObject(model.additionalProperties) then model.additionalProperties else false
  }

Not sure why model.additionalProperties is checked if it's an object or not.

As a short term solution, I can specify my schema as:

{
  "properties": {
    "any-object": {
         "type": "object",
         "properties": {},
         "required": true,
         "additionalProperties": {"foobar": true}
     }
   }
}
