Wrong schema generated for generics

[rp-work]

Hi,
I try to use the tool to generate schema for a generic interface which contains a map.
Here is my strip down interface ts code

interface Base\<dummy\> {
	map: { [key: string]: dummy };
}

interface Test extends Base\<string\> {
}

The tool generates the following schema for type Test

{
    "$ref": "#/definitions/Test",
    "$schema": "http://json-schema.org/draft-04/schema#",
    "definitions": {
        "Test": {
            "properties": {
                "map": {
                    "additionalProperties": {
                        "$ref": "#/definitions/dummy"
                    },
                    "type": "object"
                }
            },
            "type": "object"
        },
        "dummy": {
            "type": "object"
        }
    }
}

I would expect the type of dummy be string instead of object.
Is this a bug ?

Yes, this looks like a bug.

My other project, https://github.com/vega/ts-json-schema-generator, generates the correct schema so you could use that instead.

{
  "$ref": "#/definitions/MyObject",
  "$schema": "http://json-schema.org/draft-04/schema#",
  "definitions": {
    "MyObject": {
      "additionalProperties": false,
      "properties": {
        "map": {
          "additionalProperties": {
            "type": "string"
          },
          "type": "object"
        }
      },
      "required": [
        "map"
      ],
      "type": "object"
    }
  }
}

Thanks for reply.
I will give the new tool a try.

Unfortunately the ts-json-schema-generator tool has other issues which prevents me from using it at the moment. Any chance to get this issue fixed in the typescript-json-schema tool? Or is this project deprecated and the other tool is the way to go anyway? I'm confused :)

I tried to track down the problem myself but only found out that the magic most likely must be added here: https://github.com/YousefED/typescript-json-schema/blob/master/typescript-json-schema.ts#L773
But I'm a complete noob when it comes to TypeScript internals so I have no idea how to fix this...
