Hi!
I have a very basic workflow. In my workflow I have a diverging gateway.
In this gateway I use a service to control the flow.
My problem is that my service is a transactional service (I use spring-data in it), and as soon as I use this service to decide, I get an exception like the following.
How can I use a transactional service in the gateway?
Thank you
