The NF wrongly computes cardinality when translating MultiBody model

[Francesco Casella]

The code to simulate ​Modelica.Mechanics.MultiBody.Examples.Elementary.RollingWheel is generated successfully when the model is tested by Hudson, which I assume calls the simulate API function.

However, if I try to simulate it in OMEdit with -d=newInst, the following error is obtained:

[1] 14:15:49 Symbolic Error
[Modelica.Mechanics.MultiBody.Interfaces: 732:5-733:65]: Assertion triggered during translation: "Connector frame_a of visualizer object is not connected".

which is wrong, since the port is definitely connected to a fixed component, see ​the source code.
This is the transcript of the OMEdit log:

whi
showing that the translate API is used instead.

It seems that something goes wrong there with this cardinality-based assert.
