When implementing logic to work with business processes with Java, (e.g. for delegates), it is important that the expressions used in the model are matching the actual available code. For example, during development, the amount and identifiers of activities and process variables are frequently changing. This bears the risk that code breaks or is incomplete. The benefits of static typing and strong references get lost when working just with string references.
In this session I will show how the BpmnParser can be used to instantiate models and how based on this to write a code generator that produces glue code, e.g. for Java or Typescript. With this I will show how this helps to write more robust code where breaking changes are detected at build time already.
