Hi,
As I currently discovered the aggregate is “created“ at the beginning of the action. So, the "result" is available even before it is executed or even if it is never executed. It will just be empty if you try to use, as it was not executed.
It can lead to undesired behavior if accidentally assign aggregate result in the wrong scope... It would be helpful to have a warning for such situation that the result of the aggregate will not yet be available.
