Issue with additionalProperties

[bellostom]

Hi

First of all nice job on the validator
However, I have stumbled upon an issue with the additioalProperties
Consider the below schema and data, which I tried to validate online at
https://json-schema-validator.herokuapp.com/
and it does not pass validation (as it should not)

Schema
{
"type": "object",
"properties": {
"class": {
"type": "string"
},
"meta_keywords": {
"type": "string"
},
"meta_description": {
"type": "string"
},
"header": {
"type": "string"
},
"footer": {
"type": "string"
},
"page_title": {
"type": "string"
},
"containers": {
"type": "array",
"items": {
"type": "object",
"properties": {
"id": {
"type": "integer"
},
"template": {
"type": "string"
},
"columns": {
"type": "object",
"additionalProperties": {
"type": "array",
"items": {
"type": "integer"
},
"uniqueItems": true
}
}
}
}
}
},
"required": [
"header",
"footer",
"page_title",
"containers"
]
}

data
{"page_title":"wefewfw","meta_keywords":"","meta_description":"","containers":[{"id":1412867034986,"template":"6-6","columns":{"column1":["13"],"column2":["14"]}}],"header":"10","footer":"9"}

However, when I use your class it passes.

Regards
