In case of the non-physical collider object, trigger->getNumContacts() is valid  but only can't fire callback function?

You're right, callback functions are only fired when a physical object (with body and shape assigned) gets inside or outside the physical trigger.

The trigger has its own physical shape, so both Shape-Shape and Shape-Surface collisions are detected for it in accordance with conditions described in this article.

Thus, in case of a non-physical collider object, no callbacks will be fired, but a contact with this collider object will be detected and the counter value returned by the  trigger->getNumContacts() will contain this contact.

I hope I understood your question right.

Thanks!
