Automatically fill fields from values in other fields

[jdp]

It would be great to be able to automatically update fields with the values of other fields as they change. The json-editor project supports this with the watch and template extensions to JSON schema.

You can achieve what I assume a similar behavior using dynamic schemas (see example http://brutusin.org/json-forms and its schema resolver). The idea is to have schema parts (subchemas) whose definiton is dynamic and changes depending on the values of other parts.
