Command line used for generation
java -jar .\openapi-generator-cli-4.0.0-beta3.jar generate -i default.yaml -g cpp-pistache-server -o pistache
Steps to reproduce
Run the above command with the included yaml. Notice that DefaultRequest::fromJson() doesn't deserialize anything. Then remove required items from DefaultRequest in the yaml and generate the server again. DefaultRequest::fromJson() will correctly check if the items exist and deserialize them.
