5308	The NF wrongly computes cardinality when translating MultiBody model	Francesco Casella	Per Östlund	"The code to simulate [https://libraries.openmodelica.org/branches/newInst/Modelica_trunk/files/Modelica_trunk_Modelica.Mechanics.MultiBody.Examples.Elementary.RollingWheel.err 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 [https://github.com/modelica/ModelicaStandardLibrary/blob/2da48301b8c3071158aa5ada8693767e6717ca47/Modelica/Mechanics/MultiBody/Visualizers.mo#L826 the source code].

showing that the {{{translate}}} API is used instead. 

It seems that something goes wrong there with this cardinality-based assert."	defect	new	high	2.0.0	New Instantiation	v1.14.0-dev-nightly			Adeel Asghar
