3450	Cyclic dependant parameter error in replaceable function	Markus Dahl	somebody	"Running the ExampleModel from the package below will yield the following error:

  15:55:39 Translation Error
  [CTest: 9:47-9:80]: Cykliskt beroende konstanter eller parametrar hittades i definitionsomr�de : {x}.

or translated to english..

   Error: Cyclically dependent constants or parameters found in scope : {x}.

In the ambient model, changing the modifier x=x in the redeclaration of the function to x=5 will resolve the error. However those two statements should be equivalent.

Package:
{{{
package CTest

  model ExampleModel
    Component component;
    inner Ambient ambient;
  end ExampleModel;

  model Ambient
    extends CTest.AmbientBase(redeclare final function func = CTest.func(x = x));
    parameter Real x = 5;
  end Ambient;

  partial model AmbientBase
    replaceable partial function func = CTest.func;
    parameter Real var_value = 2;
  end AmbientBase;

  model Component
    outer Ambient ambient;
    parameter Real var = ambient.func(ambient.var_value);
    Real z;
  equation
    z = var;
  end Component;

  function func
    input Real x;
    output Real y;
  algorithm
    y := x + 2;
  end func;

end CTest;
