Zero values parameter error

[ekorian]

Setting a parameter value to zero whether it's a real, a natural or a boolean parameter always ends up with an error on the supervisor output independently of the constraint ("0 ... 255","*", "0, 1").
e.g:
Got exception in _run(), returning <Exception: e95ba946509eb2fc3318581b3db4c212 'missing parameter scamper.ping.tos'>

Would it be possible to add the full stack trace to this issue?

[ekorian]

Sure

This seems like a check against true where there should be a check against None.

Cannot reproduce with loopback test with empty string (which would also fail such a check): @ekorian, let's take a look at this in Milan next week.
