Per the TopologyBuilder documentation Generate List From Input Faces Gives the option to create a list on the Node and Edge output ports that relate to information from the input faces. 

 

However when attempting to do so in FME 2021.2, the attributes are show on the canvas, but are not present when the Node output is inspected.

TopologyBuilderSettingsTopoBuilder-resultsWhy isn't the _faces{} list propagated onto the node like is to the edge?

Hi @jdh​ I'm not sure if this has ever worked! I've filed FMEENGINE-72934 about this. Thanks for pointing it out to us.

I'll admit I don't think I've ever tried this before.

In this particular use case, I need to identify nodes from what are essentially sets of thiessan polygons that are not on the perimeter of the adjoining polygons.

I had hoped it would be a simple case of looking for the universe face_id 0 on the node.
