Use of a component parameter as a value is currently not supported.

The folowing CIF model generates this error:

group def A():
  alg int var1 = 1;
  alg int var2 = 2;
end

group def B(A a):
  alg int x = a.var1;
  alg int y = x + a.var2;
end

group def C(A a):
  b: B(a);
end

a: A();
c: C(a);

While you could rewrite the model as follows, it becomes less clean (and less adaptable once the model of A grows).

group def A():
  alg int var1 = 1;
  alg int var2 = 2;
end

group def B(alg int var1, var2):
  alg int x = var1;
  alg int y = x + var2;
end

group def C(A a):
  b: B(a.var1, a.var2);
end

a: A();
c: C(a);
