Almost a year ago I asked the question if anyone knew why it wasn't possible to configure whether or not to perform the Delete activity with or without events.
This is possible for committing, and it is also an available action in the Java API, see deleteWithoutEvents.
Please implement this option. Especially when deleting lists, it can add a lot of overhead if events are executed.
For consistency and completeness, do the same for the Create and Rollback activities? Then that would cover all possible event handler types in Mendix.
