I'm working with complex features on the GeoServer and the app schema extension.
My understanding of the app-schema extension is that you are able to map complex features through a WFS at the end. In other words, the app-schema is the connecting element between your complex data and a GIS software which do the WFS request.
Or is the extensions only responsible to create a valid WFS response of the complex features and the visualization of them is another part of the story?
When I load the WFS Layer in QGIS the mapping is wrong. Only one layer will be added with all information about the complex features. In addition, QGIS can not interpret the geometry (no data is displayed).
The only way to display the data is to use the GML Application Schema toolbox QGIS plugin.
When I am using the plugin, my complex features are stored in three separate layers and will be displayed successfully.
