Recursive rendering needs work

Hello,

• swagger-ui version 3.0.17
• a swagger file reproducing the issue : https://gist.githubusercontent.com/julienkosinski/287a3b77e25a6ca3e6f7a0293bea4e3d/raw/fd94d4f1457ccbaa538f27996dba5d077d9c6f36/gistfile1.txt

I have the following model definitions spec:

    "definitions": {
        "models.Equipment": {
            "title": "Equipment",
            "type": "object",
            "properties": {
                "Features": {
                    "type": "array",
                    "items": {
                        "$ref": "#/definitions/models.Feature"
                    }
                },
                "Id": {
                    "type": "integer",
                    "format": "int64"
                },
                "IdType": {
                    "type": "string"
                },
                "Name": {
                    "type": "string"
                },
                "Price": {
                    "type": "integer",
                    "format": "int32"
                }
            }
        },
        "models.Feature": {
            "title": "Feature",
            "type": "object",
            "properties": {
                "Equipments": {
                    "type": "array",
                    "items": {
                        "$ref": "#/definitions/models.Equipment"
                    }
                },
                "Id": {
                    "type": "integer",
                    "format": "int64"
                },
                "IdFeature": {
                    "$ref": "#/definitions/models.Feature"
                },
                "Name": {
                    "type": "string"
                }
            }
        }
    }

In the Feature model, the Equipments property is defined as an array of Equipment models, but Swagger UI 3.x renders it as an empty array []. Everywhere Feature model is used, like as examples for POST method in Feature I have this kind of display.

We think it may be a bug caused by circular references. Thanks to Helen.

Thank you very much!

Start by loading the linked Swagger file in Swagger UI 3.0.17 and reproducing the Feature model display. Trace how the recursive Equipment and Feature references are rendered, then verify that the Equipments array and POST examples no longer appear empty while circular references remain safe.
