+4I'm trying to setup the children and parents list attribute for export to CityJSON. Therefore I thought to use the listbuilder, but I get a different result than it should be. This example is how it should be:
And this one is my result. It looks like there is an extra layer in it.
How can I solve this?

Hi
Most of the list collector tools in FME are designed to work with multiple sub-attributes on a list, instead of the very simple list you require. However, you can generate the simple list with an Aggregator and an AttributeSplitter:
I am attaching a workspace to illustrate.

Here is just a very simple example, but with the same result.
+62Okay, I think what's happening here is not so much that there's an extra layer to it, but that FME 2024 displays lists in a different way than previous versions. There have been some changes to the Feature Information panel around that time.
When you write this out to CityJSON, do you get the correct result?
+4No, I don't get the correct result.
The cityjson format attribute must be cityjson.children{}, but when I sent it to the writer I get cityjson.children{}.cityjson.children.
If I plot that on the example, it should be _list{}, but I get _list{}._creation_instance.
