oneOf with $ref seems not be working

[philippecarle]

Hi,

I've played with GeoJson schema validation and can't figure out why I keep getting Failed to match exactly one schema error.

I guess it may be due to a wrong handling of "oneOf" in combination of "$ref" ?

Here is my schema :

{
  "$schema": "http://json-schema.org/draft-04/schema#",
  "title": "Geo JSON object",
  "description": "Schema for a Geo JSON object",
  "type": "object",
  "required": [ "type" ],
  "oneOf": [
    { "$ref": "#/definitions/feature" },
    { "$ref": "#/definitions/featureCollection" }
  ],
  "definitions": {
    "feature": {
      "title": "Feature",
      "description": "A Geo JSON feature object",
      "required": [ "geometry", "properties" ],
      "properties": {
        "type": { "enum": [ "Feature" ] },
        "geometry": {
          "type": [ "array","null" ]
        },
        "properties": {
          "type": [ "object", "null" ]
        }
      }
    },
    "featureCollection": {
      "title": "FeatureCollection",
      "description": "A Geo JSON feature collection",
      "required": [ "features" ],
      "properties": {
        "type": { "enum": [ "FeatureCollection" ] },
        "features": {
          "type": "array",
          "items": { "$ref": "#/definitions/feature" }
        }
      }
    }
  }
}

It's working when I try to do this against a GeoJson feature :

{
  "$schema": "http://json-schema.org/draft-04/schema#",
  "title": "Geo JSON object",
  "description": "Schema for a Geo JSON object",
  "type": "object",
  "required": [ "type" ],
  "oneOf": [
    {
      "title": "Feature",
      "description": "A Geo JSON feature object",
      "required": [ "geometry", "properties" ],
      "properties": {
        "type": { "enum": [ "Feature" ] },
        "geometry": {
          "type": [ "array","null" ]
        },
        "properties": {
          "type": [ "object", "null" ]
        }
      }
    }
  ]
}

Hi,

Have you try to valide your json with the validate-json command line tool? Json context is just a bridge to https://github.com/justinrainbow/json-schema.

Ok I've been working once again on this and it validates with the justinrainbow's package.

Here are the files used for my tests :

I really can't figure out what I'm doing wrong :(

Ok i got it working by pointing on the dev-master of this repo… now i'm getting a "The maximum stack depth has been exceeded" error from justinrainbow/json-schema which has been fixed since more than one year. I should really consider coding these tests with a very verbose set of PHPunit tests, as this package, regarding to its very outdated dependencies and to the lack of patched versions, can't meet production requirements… :(
(i'm not whining here, just saying the purpose of this can't fit to "real-life" testing)

Ok, it’s related to #181
