JSON Schema Template and JSON Editor - json

Question

I have been struggling for a few days, trying to use the JSON Editor Javascript plugin. I am using the SWIG JS engine, but I am open to propositions that will solve my issue.
I created a JSON Template that works fine so far, but that does not achieve entirely what I need to do, and I tried understanding and using the syntax provided by the JSON Editor github page, but no luck so far.
How can I make the template behave as follow :
If the value of features.type == "Point", then I want features.display to have a property of the type "#/definitions/marker". Otherwise (features.type == "Polygon") I want features.display to have a property of the type "#/definitions/area". The same goes for filter.display.
So far, I use the "oneOf" property, because it's the closest to what I want, but definitely not quite it.
Thanks for your help !
Kind regards.
Here is my JSON Schema so far :

The only way to enforce this (until appareance of jsonschema draft 5) is to use the enum as a discriminator. You can find an example in How to use dependencies in JSON schema (draft-04)
