Description

Since ResourceAllOfNested (refer to spec below) inherits all fields from ResourceBaseWithProp, ResourceAllOfNested MUST contain prop_field. However, prop_field is missing from the final output of ResourceAllOfNested.

SwaggerUI correctly depicts the expected fields in ResourceAllOfNested:

Not regression. Using latest docker image built on 22 Aug 2021 (today).

Steps to reproduce

Generate code using cli with any of the generators.

The following are two samples from go-server and typescript.

go-server generator

type ResourceAllOfNested struct {

	Name string `json:"name,omitempty"`

	Other string `json:"other,omitempty"`
}

typescript generator

export class ResourceAllOfNested {
    'name'?: string;

    'other'?: string;

    static readonly discriminator: string | undefined = undefined;

Expected: both to contain prop_field.

@lwj5 can you please try to enable REFACTOR_ALLOF_WITH_PROPERTIES_ONLY in the openapi-normalizer? that should "fix" the issue for your use case
