The generic port does provide the attributes but you need to expose them, luckily you can use the import function in the attributeexposer and get all the attributes.

The <Generic> output port will give you both the geometry and the attributes, but you'll have to expose the attributes manually. You can verify this by sending the <Generic> port to the Inspector and click on an object and see the attributes on the right.

Yeah, I know that. But in order to expose attributes I need to know what they are. Any other reader automatically exposes all atributes without manually instructing what attributes to expose. This is kind of behaviour I want from FeatureReader.

Or add a new one.

This is the right idea, but no progress since 2015...
