I've used the Airport demo as a base and all features are connected properly in the output file except that the point feature is missing. I've attached the image below where you can see that the gml_object_name is populated just like in the demo. I've tested all posibilities in the demo and reduced the attributes to gml_id and gml_parent_id just to remove any other possibilities.
Could you tell me why is this happening? What is expected for the ElevatedPoint to be added?
Thanks
