Description
I'm following this tutorial (http://www.qgistutorials.com/en/docs/custom_python_functions.html) on custom expressions and all goes well - my function shows up in the custom section and seems to work for the preview giving 21S for the first feature. When I extend the selection expression to GetUtmZone() = '21S' the output preview still says 1. But when I click on the select button no features are selected.
This works on 2.14.x but fails on 2.18.x.
Matthias Kuhn suggested adding usesgeometry=True to the decorator but that seems not to help.
