range in connect equation fails

[Jens Frenkel]

For the simple Model

model IndexConnect
  connector A
    Real a;
  end A; 
  
  constant Integer n=5;
  A a[n];
equation
  a[1].a = 1;
  connect(a[1:n-1],a[2:n]);
end IndexConnect;

instantiateModel result with

class IndexConnect
  constant Integer n = 5;
  Real a[1].a;
  Real a[2].a;
  Real a[3].a;
  Real a[4].a;
  Real a[5].a;
equation
  a[1].a = 1.0;
end IndexConnect;

As you can see the connect equation is not expand to

a[1].a = a[2].a;
a[2].a = a[3].a;
a[3].a = a[4].a;
a[4].a = a[5].a;

Even try to rewrite the connect as a loop:

for i in 2:n loop
  connect(a[i-1],a[i]);
end for;

results in:

a[1].a = a[2].a;
a[1].a = a[3].a;
a[1].a = a[4].a;
a[1].a = a[5].a;
