Comment 2 for bug 256940

The status_upstream problem is different. status_upstream is published as a List of Choice objects. I've never seen that before. lazr.restful knows how to describe a single Choice in WADL, but not a List of Choices. Properly describing that in WADL would require publishing the choice and each of its values as a resource (so that you could have a list of references to its values), which would be a big change.

I recommend checking whether status_upstream really needs to be a List, and if so, filing a separate bug about it.
