validation error for oneOf objects with 'additionalProperties':false

[tdamsma]

Sorry for the title, best see the examples for what I mean. The form on this playground link not validate, while I think it should.

Removing the 'additionalProperties':false on line 27 returns a
schema that validates as expected, however now the validation is too lax.

I'm trying to create forms to generate valid jsonschema's and it's proving quite challenging

after more digging around I found that the combining oneOf and additionalProperties is not a good idea. See also python-jsonschema/jsonschema#193 and especially the chapter "Additional properties inside compound keywords anyOf, oneOf, etc." in the Ajv faq

See this playground for a working example for a combination of mutually exclusive oneOf fields without using 'additionalProperties':false
