Error during schema validation #376

I have the following schema:
{ "$schema": "http://json-schema.org/draft-04/schema#", "type": "object", "oneOf": [ { "properties": { "localeId": { "type": "integer" }, "answer": { "type": "string" }, "inputs": { "type": "array", "items": { "type": "object", "$ref": "#/definitions/inputs" } } }, "required": [ "localeId", "answer" ] }, { "properties": { "answerId": { "type": "integer" }, "inputs": { "type": "array", "items": { "type": "object", "$ref": "#/definitions/inputs" } } }, "required": ["answerId"] } ], "definitions": { "inputs": { "properties": { "id": { "type": "integer" }, "value": { "type": "string" } }, "required": [ "id", "value" ] } } }

If I want to validate data, the JsonSchema\SchemaStorage::resolveRef were called with parameter "#/definitions/inputs". The problem is that JsonPointer returned an empty filename in JsonSchema\SchemaStorage::addSchema and the uriRetriever try to get contents from a empty file which runs into an error.

I'm happy to deal with this one - already trapping the error in 39569bf. Will go hunting for the root cause and squash it this weekend.

For anyone else following along, here's the schema from the original comment, with nicer formatting:

{
    "$schema": "http://json-schema.org/draft-04/schema#",
    "type": "object",
    "oneOf": [

                "answer": {
                    "type": "string"
                },

In order to resolve internal $ref references within a user-provided
schema, SchemaStorage needs to know about the schema. As user-supplied
schemas do not have an associated URI, use a dummy / internal one instead.

Throws an exception when the ref can't be resolved to a useful file URI,
rather than waiting for something further down the line to fail after
the fact.

* Refactor defaults code to use LooseTypeCheck where appropriate

* Test for not treating non-containers like arrays

* Update comments

if they are marked as required.

* Fix infinite recursion via $ref when applying defaults

* Add missing second test for array case

* Add test for setting a default value for null

* Also fix infinite recursion via $ref for array defaults
