The same event(DOWN)is used in multiple lower-level(child)charts within a parent chart. When the DOWN event is triggered in any of these child, it propagates to parent chart.

In MATLAB Stateflow, I’m using the same event (DOWN) in multiple lower-level (child) charts within a parent chart. When the DOWN event is triggered in any of these child charts, it also propagates to the parent chart, unintentionally triggering logic there.

How can I prevent the DOWN event triggered in a child chart from being received or acted upon by the parent chart? I want to reuse the same event name (DOWN) across multiple child charts without causing conflict or event propagation to the parent.

I don't believe you can use the same name this way without using atomic subcharts and parameter mapping (Map Variables for Atomic Subcharts and Boxes - MATLAB & Simulink), and I believe atomic subcharts would not be available for MATLAB Stateflow, since it requires using Simulink libraries. Unfortunately I think this will require using a different name for the parameters in the subchart if this variable is not supposed to be shared/affecting the parent.
