Hi!
This is a known regression. Fix is going to be on production in a few days. For now - just add extension .java to your models manually.

Thank you. another question, why my code does not appear inmeniya business logic

Do you run ./CodeRunner.sh script from /bin folder? If yes - then post here coderunner start logs. If no - then try to run it and check “Business logic -> Debug” tab.
