@roarmstrong @davidcaron @huard Please have a look it this PR. File storage currently does not work on master ... didn't notice before. I was using the latest release of pywps in emu.

I ran into the same issue a couple hours ago 🙂
I came into the same conclusion as you did, I think this will fix it.

[huard]

Not familiar with this part of the code.

[roarmstrong]

Fix looks good to me, apologies I didn't catch this in the original PR!

[jachym]

if I reed this correctly, travis is complaining about the code style?

otherwise it can be merged IMHO, thank you
