Description
In Modelica.Blocks.Examples.BooleanNetwork1:
[Modelica 3.2.1/Blocks/MathBoolean.mo:253:5-254:37:writable] Error: Model is structurally singular, error found sorting equations 10: not showValue4.showActive = not Modelica.Math.BooleanVectors.anyTrue({or2.u[1], xor1.u[2]});
for variables
Why doesn't this believe there are any variables to sort? And why isn't the equation simplified to:
showValue4.showActive = Modelica.Math.BooleanVectors.anyTrue({or2.u[1], xor1.u[2]});
