Cyclic dependant parameter error in replaceable function

[Markus Dahl]

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.

Below is the package

package CTest

model ExampleModel

Component component annotation(Placement(visible = true, transformation(origin = {0, 0}, extent = {{-10, -10}, {10, 10}}, rotation = 0)));
inner Ambient ambient annotation(Placement(visible = true, transformation(origin = {-90, 70}, extent = {{-10, -10}, {10, 10}}, rotation = 0)));
annotation(Diagram(coordinateSystem(extent = {{-148.5, -105}, {148.5, 105}}, preserveAspectRatio = true, initialScale = 0.1, grid = {5, 5})));

end ExampleModel;

model Ambient

extends CTest.AmbientBase(redeclare final function func = CTest.func(x = x));
parameter Real x = 5;
annotation(Diagram(coordinateSystem(extent = {{-148.5, -105}, {148.5, 105}}, preserveAspectRatio = true, initialScale = 0.1, grid = {5, 5})));

end Ambient;

partial model AmbientBase

replaceable partial function func = CTest.func;
parameter Real var_value = 2;
annotation(Diagram(coordinateSystem(extent = {{-148.5, -105}, {148.5, 105}}, preserveAspectRatio = true, initialScale = 0.1, grid = {5, 5})));

end AmbientBase;

model Component

outer Ambient ambient;
parameter Real var = ambient.func(ambient.var_value);
Real z;

equation

z = var;
annotation(Diagram(coordinateSystem(extent = {{-148.5, -105}, {148.5, 105}}, preserveAspectRatio = true, initialScale = 0.1, grid = {5, 5})));

end Component;

function func

input Real x;
output Real y;

algorithm

y := x + 2;
annotation(Diagram(coordinateSystem(extent = {{-148.5, -105}, {148.5, 105}}, preserveAspectRatio = true, initialScale = 0.1, grid = {5, 5})));

end func;
annotation(Diagram(coordinateSystem(extent = {{-148.5, -105}, {148.5, 105}}, preserveAspectRatio = true, initialScale = 0.1, grid = {5, 5})));

end CTest;
