Validation failure

[tumkurrunner]

Description:
Problem using Inheritance model
I have a base type Activity and Subtypes SubActivity1 SubActivity2 & SubActivity3 with discriminator propertyName set correct but still I get an error request should match exactly one schema in oneOf. Just to make if the spec is valid I tried https://bitbucket.org/atlassian/swagger-request-validator/src and validation is successful.

I have added the test yaml for reference.

@tumkurrunner can you provide the example request
also, i see that the DecisionRequest requires actor, but actor is not defined as a property anywhere.

it would be good to solve these issues first i.e. that one noted above. also, it will be great if you can provide a canonical version of this spec with the minimum to reveal the error. it will certainly help to make the investigation simpler.

Don't worry I found a work around, I got the answer from here OAI/OpenAPI-Specification#2141 (comment).

[cdimascio]

@tumkurrunner i'm working on an initial version of discriminator support. it will start by supporting top level types. will expand it to this use case. #461

[Hono76]

I am trying to use the discriminator feature .What's the actual state regarding this matter? Can anyone shed some light on it?
Is it supported on validator ?

[cdimascio]

Closing as it is a Duplicate of the following #104

Additionally, top level (not full discriminator) discriminator support exist exists #461
