Nanoflow XAS requests

I have a nanoflow with no database retrievals but still makes XAS requests in the network tab, why is this?

This is going away as of 9.24:

“The Mendix Client now now retrieves non-persistable objects over a direct association without sending a request as long as they have no virtual attributes”


Edit: I should say that it’s partially going away. It is my understanding that retrieving a persistable entity via the association will still trigger a network request.
