L3 - Default What are the steps to reproduce your problem?
- Create the model with message end event, which is configured to be executed by external task (see attach). Important: messageEventDefinition node must NOT have id field.
- Deploy the model
- Start the process instance
- Change a model slightly and deploy the second version
- Try to generate Migration plan
What is the problem?
