Cannot set message reference on message start event

[maratkalibek]

Hello, during designing a new process in flowable modeler I cannot select message reference for the message start event.

In the properties message reference field for message start event is dropdown, but it should be text.

Is there any setup that must be done before using message references?

This is because the process property “message definitions” is not set

Thanks a lot! Works as expected.
