Wrong illegal subscript

[Rüdiger Franke]

6 models of the PowerSystems library fail for the reason reported here. See:

​https://test.openmodelica.org/libraries/PowerSystems/BuildModelRecursive.html

The model

model Modulator
  parameter Integer m = 3;
  Modelica.Blocks.Interfaces.BooleanOutput[2 * m] gates;
  final parameter Integer[m] pgt = 1:2:2 * m - 1 "positive gates";
  final parameter Integer[m] ngt = 2:2:2 * m "negative gates";
initial algorithm
  for k in 1:3 loop
    gates[{pgt[k], ngt[k]}] := {true, false};
  end for;
equation
  for k in 1:3 loop
    when time > 0.5 then
      gates[{pgt[k], ngt[k]}] = pre(gates[{ngt[k], pgt[k]}]);
    end when;
  end for;
end Modulator;

generates the error:

[1] 08:38:24 Translation Error
Error occurred while flattening model Modulator

[2] 08:38:24 Translation Error
[/home/user/work/Modulator.mo: 8:5-8:45]: Variable gates[{pgt[k], ngt[k]}] not found in scope Modulator.$for loop scope$.

[3] 08:38:24 Translation Error
[/home/user/work/Modulator.mo: 8:5-8:45]: Illegal subscript {pgt[k], ngt[k]} for dimensions 6 in component gates[{pgt[k], ngt[k]}].

Should be fixed in r24568.
