[C#] Missing Models for Map types and incomplete types for Api Endpoints

[etherealjoy]

Description

With the following valid spec

• The map models are not generated and the Api is having a wrong type for the response associated with map.

• When a map is part of an object the model is generated correctly with the map inside the object.
  When a model type is a map, there is incorrect generation of code either as an inline model or as a map when referred from another model.

• General issues with inline models always being reported as objects

Is the Map support broken in C#

[etherealjoy]

seems broken on golang as well.
Strange it is not working on Qt5 as well.
For Qt5 I have added nested arrays and nested map support before and now it is not working.

[jmini]

It was reported to be broken in java as well, if I understood #191 correctly.

[etherealjoy]

For golang for example
java -jar /home/dev/openapi-generator/modules/openapi-generator-cli/target/openapi-generator-cli.jar generate -i ./api.yaml -o ./gengo-server -g go-server --additional-properties packageName=cta --additional-properties hideGenerationTimestamp=true

This spec creates a valid model with a map

  Options:
    type: "object"
    properties:
      Config:
        description: "List of configuration options"
        type: "object"
        additionalProperties:
          type: "string"

This one when referenced inside another model creates an error

  ResourceOperations:
    description: "An object describing the operations"
    type: "object"
    additionalProperties:
      type: "string"

[etherealjoy]

I have not even tried nested containers as yet. Does not look good for now.

[topce]

this is broken also in typescript-angular code generator

[wing328]

UPDATE: I'm able to identify the issue and working on a fix (which requires changing how Map schema is handled in many places). I'm aiming for a fix ready for test by tomorrow.

(codegen also has the same issue so it's not a bug we introduced to openapi generator)

[wing328]

UPDATE: I'm hoping to release the fix tomorrow (Wed). Sorry for the delay.

[wing328]

Filed #360 to fix it. Please give it a try when you've time.
