connects for array components do not work anymore

[Christian Schubert]

Hi,

we have a simple N pendulum model, which reads

model NPendulum
  constant Integer N=10;
  World world;
  Body bodies[N];
  RevoluteJoint joints[N];
equation
  connect(world.frame_b, joints[1].frame_a);
  connect(joints.frame_b, bodies.frame_a) "Connects all instances at once";
  connect(bodies[1:N-1].frame_b, joints[2:N].frame_a) "Connects to next chain";
end NPendulum;

As of r18987 this model doesn't translate anymore, because an assertion is raised
{{{
[Joints.mo:310:5-311:62:writable] Error: Assertion during Translation failed: "Connector frame_b of revolute joint is not connected".
}}}

It would be great if someone could take a look at this.

I will attach the model and a mos file, so that you can test it yourselves.
