Issue with Real*Complex product in NF

Description

Please check Modelica.Magnetic.FundamentalWave.Examples.BasicMachines.AIMC_Conveyor. The following error is reported:

Error: Cannot resolve type of expression aimc.stator.electroMagneticConverter.singlePhaseElectroMagneticConverter.effectiveTurns * 
Modelica.ComplexMath.exp(Complex.'constructor'.fromReal(0.0, aimc.stator.electroMagneticConverter.singlePhaseElectroMagneticConverter.orientation)). 
The operands have types Real, Complex in component <NO_COMPONENT>.

This issue affects all Modelica.Magnetics models. If I am not mistaken, it also prevents the PowerGrids library to compile, as I have a similar issue involving sqrt(3)*Complex(v_re,v_im).

@perost, unfortunately this issue is still unsolved, as it is for the PowerGrid library, where I still get

Cannot resolve type of expression sqrt(3.0) * generators.port.v. 
The operands have types Real, Complex in component <NO_COMPONENT>

What is strange is that models such as

model Test
  Complex z,w;
  Real x;
equation
  z = Complex(1,time);
  w = sqrt(3)*z;
end Test;

work fine.

Resolution: fixed
Status: newclosed

Fixed in 0095bb1. The model now fails due to what superficially looks like a constant evaluation issue, but the actual issue is because array bindings coming from an outside scope isn't handled correctly.
