Mendix uses PascalCase as default for the domain model, which is perfectly fine.
However, when creating a Message Definition for publishing a REST API, I prefer to use camelCasing (as it is a general recommendation) in the message body.
Please make it possible to automatically use camel case when setting up JSON Message Definitions, because manually changing every attribute is quite cumbersome (see example below).
Thanks a lot!
