Error to use a vector of PP external routines

[Rodolfo Rodrigues]

I would like to calculate a specific physical property (enthalpy) in a range of temperature. For this, I used a loop structure to attribute the calculated values.

for i in [1:N+1]
   h(i) = PP.VapourEnthalpy(T(i),P,x);
end

See all sample in the file attached below.

The model is consistent (12 variables, 7 equations, and 5 specifications) but EMSO returns that error message to each position:

error in external routine 'VapourEnthalpy' input argument 1 expects for length 1

On the other hand, the sample of a pipe (file 'pipe.mso' below) uses the same resource and it runs perfectly.

This problem happens only if the property calculation is carried out in the FlowSheet? level. When it is done inside a model works fine.
