FieldMap provides wrong JsonSchema in RAML

[leonadler]

FieldMap is a "hash with any value type" model - { [k: string]: any } in TypeScript.
The RAML wrongly returns a type that has a single boolean empty property.

"fields": {
    "type": "object",
    "id": "urn:jsonschema:com:gentics:mesh:core:rest:node:FieldMap",
    "required": true,
    "description": "Dynamic map with fields of the node language specific content.",
    "properties": {
        "empty": {
            "type": "boolean"
        }
    }
}

This produces an incorrect TypeScript model:

export interface FieldMap {
    empty: boolean;
}

GenericResponse is correctly typed in the RAML, FieldMap needs to have a similar JsonSchema:

"fields": {
    "type": "object",
    "id": "urn:jsonschema:com:gentics:mesh:core:rest:node:FieldMap",
    "required": true,
    "description": "Dynamic map with fields of the node language specific content.",
    "additionalProperties": {
        "type": "any"
    }
}

This would produce the correct TypeScript model:

export interface FieldMap {
    [key: string]: any;
}
