Co-Sim FMIs "maxOutputDerivativeOrder" set to wrong value

Description

On the workshop today, I got the feedback that we generate co-simulation FMIs in which the value of field maxOutputDerivativeOrder is set to 1, but retrieving the first derivative of the outputs lead to an error (I suppose when calling the function fmi2GetRealOutputDerivatives).

I didn't reproduce the problem since I don't have any code that would use that feature. I got an OM generated FMU that should should this problem. Find this FMU and related Modelica models attached.

I fixed the maxOutputDerivativeOrder attribute a while back. It is now set to 0, because OpenModelica doesn't support output derivatives yet.
