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.

Below is the package
