-Utilizing exclusive event-based gateway in cases like this is a rather common mistake. What's missed in the diagram below is that the payment may arrive while we are discussing the issue with the client. If this happens, the message won't be catched and the process will hang after returning to the event gateway.+Non-interrupting looks better but it won't let resetting the timer to the new due date:

-  - Although [[en:rule:one_outgoing_control_flow]] more than one flow outgoing from an element other that a gateway, it's acceptable in this technique:+  - As an exception to the [[en:rule:explicit_parallel_split|general rule]], one may initiate work and control flows directly from the start event:
