The reactor extension introduced publishing of DelegateTask/Execution on an eventBus and thus allowed loose coupling of camunda listeners and the process.

This feature was adopted to the spring boot starter. However, the reactor extension also supports CMMN files, and this was not migrated. 

We still use case management in our project and ran into errors after switching from the reactor extension to the spring native eventing.

Solution: basically copy the  cmmn transform listener to the spring boot starter event section and allow auto configuration based on the existing properties.

 

I will provide a PR for this.
