Validation by comparing 2 fields

General

Is there a way to do validation by comparing 2 fields without using a custom renderer?

Hi @collegewap ,
validation in JsonForms ist done via AJV. You can try using JsonSchema’s $data property like described in the AJV documentation: Combining schemas | Ajv JSON schema validator
Note that I have not used this before myself.
