Problems with type redeclaration in complex numbers

[Francesco Casella]

Please consider the following code fragment

package TestComplex
  package Types
    operator record ComplexVoltage = 
      Complex(redeclare Modelica.SIunits.Voltage re, 
              redeclare Modelica.SIunits.Voltage im);
    operator record ComplexCurrent = 
      Complex(redeclare Modelica.SIunits.Current re,
              redeclare Modelica.SIunits.Current im);
    operator record Impedance = 
      Complex(redeclare Modelica.SIunits.Resistance re,
              redeclare Modelica.SIunits.Resistance im);
  end Types;

  package Test
    model A
      import SI = Modelica.SIunits;
      parameter SI.Resistance R = 1;
      parameter SI.Reactance X = 1;
      parameter Types.Impedance Z = Complex(R, X);
      Types.ComplexCurrent I = Complex(1, 0);
      Types.ComplexVoltage V = Z * I;
    end A;
  end Test;
  annotation(uses(Complex(version = "3.2.1"), Modelica(version = "3.2.1")));
end TestComplex;

When compiling this, the current nightly complains that:

[1] 02:36:24 Translation Error
[TestComplex: 21:7-21:45]: Variable I: Duplicate modification of element
(redeclare .Modelica.SIunits.Current re) and  = (typed)1.0 DAE.PROP(Real, C_CONST), value: 1.0 on component re.

[2] 02:36:24 Translation Error
[TestComplex: 21:7-21:45]: Variable I: Duplicate modification of element
 (redeclare .Modelica.SIunits.Current im) and  = (typed)0.0 DAE.PROP(Real, C_CONST), value: 0.0 on component im.

plus other similar errors, but then it happily proceeds and produces correct results.

• What do these error messages mean?
• Why is correct simulation code produced after an error (not a warning)?

I can take a look at this, I think I know what the issue is.

Fixed in 0de2ae0.
