Description

I have 2 classes, the first one (One1) has some fields and the second one (Two2) has also some fields and inherits the fields from class One1.

On my Java generator this works just fine.
On my Typescript-axios generator this doesnt work, and generate me the class One1, but the class Two2 doesnt have any inherits nor fields, it will do this:

export type Two2 = One1;

Ive also tried this on the Typescript-angular & Typescript-fetch generator, they also work just fine.
Only Typescript-Axios seems to have this issue.

openapi-generator version

Tested this issue with these version of the openapi-generator-maven plugin:

• When i have time, i will edit this post or comment here.

Start by generating the supplied OpenAPI 3.0.4 spec with the openapi-generator-maven-plugin using the typescript-axios generator and REF_AS_PARENT_IN_ALLOF=true. Compare the generated Two2 model with One1 and with the typescript-angular or typescript-fetch output; done means Two2 includes the inherited and local fields rather than only being an alias of One1.
