How Do I Use Publishing Features?

The 'Publishing' flag is available on all state definitions within a flow:

When the Is Publishing? flag is enabled on a state definition, it means that an event will be published by the flow when it reaches this state. This feature is particularly useful for flo-to-flo communication, as it allows the calling flow to define specific Event Behaviour on receiving these published events from the called flow.

If you select a state definition in MPS and open the inspector (CTRL+ALT+I), you can see that there are further publishing capabilities available:

One important parameter we can configure here is 'Published Data`, which allows us to specify which data is included in the published event. Again, considering the flo-to-flo example, this can be leveraged to exchange relevant data between the called flow and calling flow (or flows).
