Hello,
This isn’t a huge thing, and maybe it’s known already, but I didn’t see anything in the forum yet. In Jmix 2.x, when including an embeddable entity in another entity and creating a view of the second entity (I only tested using a detail view), there are some warnings in the view’s descriptor file that gets generated automatically.

Perhaps I did something wrong. If so, please let me know.
