[rules-users] Flow - handling multiple events of the same kind
If the same event-node is triggered twice with different data, the same variable will be recycled for the different data payloads. How does one ensure that data is not lost? My best guess is to follow the event node with a composite node, and copy the top-level variables into the composite's variable scope in the first sub-node of the composite. But I'm not sure whether I can guarantee that the composite will be able to do that before the engine handles the second event.

Can you give us a use case for that situation? to be able to understand the problem. Greetings.
