Dear Klaus, Unfortunately looks like that what you need is currently unsupported. I gave a quick tests and the WFS sortBy work only when sorting on property names that are pointing to a root attribute, while specifying a sortBy on a chained feature attribute seems to not produce any sorting. A part from this, looks to me that even assuming to have a sortBy working on nested attributes it will not descend automatically that also the nested features (AirRoutLink if I got your use case) will be sorted.
