DimensionMismatch for OpenModelica `Modelica.Blocks.Examples.RealNetwork1` 2.0.4 FMU

[AnHeuermann]

Issue

I'm in the process of adding regression tests for OpenModelica via OMJulia.jl using FMI.jl as FMU importing tool, see https://github.com/OpenModelica/OMJulia.jl/pull/111. But FMI.jl is failing to import some of the FMUs.

The FMU is simulating with FMPy and OMSimulator.

How to reproduce

Export FMU with OpenModelica for Modelica model Modelica.Blocks.Examples.RealNetwork1 from the Modelica standard library.

Export FMU:

using OMJulia

omc = OMJulia.OMCSession()
OMJulia.API.loadModel(omc, "Modelica"; priorityVersion = ["4.0.0"], requireExactVersion = true)
fmuPath = OMJulia.API.buildModelFMU(omc, "Modelica.Blocks.Examples.RealNetwork1")
OMJulia.quit(omc)

or download pre-build FMUs (remove .zip from the filename): Linux Modelica.Blocks.Examples.RealNetwork1.fmu Windows Modelica.Blocks.Examples.RealNetwork1.fmu

Simulate with FMI.jl:

import FMI

recordValues = ["add.u[1]", "linearDependency1.y", "minMax.u[1]", "minMax.u[2]", "minMax.yMax", "minMax.yMin", "multiSwitch.expr[1]", "multiSwitch.expr[2]", "product.u[1]", "showValue3.number", "multiSwitch.u[1]", "multiSwitch.u[2]", "add.u[2]", "add.y", "integerStep.y", "linearDependency1.u1", "linearDependency1.u2", "multiSwitch.y", "product.y", "showValue.showNumber", "showValue1.showNumber", "showValue3.showNumber", "sine.y", "booleanPulse1.y", "booleanPulse2.y"]
fmu = FMI.fmiLoad(fmuPath)
FMI.fmiSimulate(fmu; recordValues = recordValues, showProgress=false)

Error message

I'm getting different error messages on different platforms, here is the Windows error message:

ERROR: DimensionMismatch: all inputs to eachindex must have the same indices, got Base.OneTo(1), Base.OneTo(1), Base.OneTo(1) and Base.OneTo(0)
