Two examples of the new Modelica.Electrical.Batteries package do not work with the new frontend

[Christian Kral <dr.christian.kral@…>]

I tested the new ​Batteries package which is going to be included in the MSL by
​modelica/ModelicaStandardLibrary#3054. When investigating the three examples of the Batteries library I was running into problems with two of the examples:

Modelica.Electrical.Batteries.Examples.BatteryDischargeCharge

Error message with new frontend:

[4] 12:38:18 Translation Error

So [5] may be the relevant hint, since the calculation of the sum seems to fail.

The example simulates OK with the old frontend

Modelica.Electrical.Batteries.Examples.CCCVcharging

Pretty much the same error message with the new frontend. The old frontend compiles and simulates fine.

@perost, is this yet another case of record issues with the old FE?

I re-tested the three examples of Modelica.Electrical.Batteries.Examples taken from ​https://github.com/modelica/ModelicaStandardLibrary/pull/3243/commits/e9ab51312f55cec9c29dc1c594754b5325f2976b with OpenModelica and found the following:

1. Modelica.Electrical.Batteries.Examples.BatteryDischargeCharge does not simulate with the old frontend any more; the new frontend does not work either; even the "Check model" doesn't work

2. Modelica.Electrical.Batteries.Examples.SuperCapDischargeCharge checks and translates but fails at the begin of the simulation with the following message:

Due to #5744 my previous report was not correct. The following updates apply (for the new frontend):

The simulation works OK and no error is triggered.

3. Modelica.Electrical.Batteries.Examples.CCCVcharging does neither check nor translate (with the new or old frontend)

Causes the same error message as in example 1.

Connected to OMSimulator unknown-linux

Examples 1 and 3 do not work with the old frontend either.

All of the Batteries models now pass the frontend, but CCCV_Stack and CCCV_StackRC seem to have some issues with expandable connectors that probably originate in the frontend.
