Description (last modified by lochel)
Why is in the following model the variable b structural parameter?
Or why is the user not allowed to change this parameter after translation?
loadString(" model A parameter Boolean b = true; Real x1,x2; Real y; equation x1 = sin(time); x2 = cos(time); if b then y = x1^2+1; else y = x2^2-1; end if; end A; "); getErrorString(); instantiateModel(A); getErrorString();
Result:
true "" "class A parameter Boolean b = true; Real x1; Real x2; Real y; equation x1 = sin(time); x2 = cos(time); y = 1.0 + x1 ^ 2.0; end A; "

The new frontend still evaluates the if-equation since that seems to be expected by both users and the backend, but unlike the old frontend it does make b final. So I guess we can consider this fixed for now.
At least b should marked somehow that it is replace, so that the Backend has a chance to detected that? For example set VariableAttributes.finalPrefix to true.
