buildModel fails when model is extended from

[Oliver Lenord]

A mos script with the code:

buildModel(EMPHYSIS_TestCases.M03_DCMotorSpeedControl.ModelsToExport.PIDController); getErrorString();

works fine.

The same mos script with

buildModel(EMPHYSIS_TestCases.M03_DCMotorSpeedControl.Controller.PID.SpeedController_continuous); getErrorString();

fails with error message:

Error: Cannot instantiate EMPHYSIS_TestCases.M03_DCMotorSpeedControl.ModelsToExport.PIDController due to class specialization PACKAGE.

even though the second model is as simple as:

within EMPHYSIS_TestCases.M03_DCMotorSpeedControl.ModelsToExport;
model PIDController
  extends EMPHYSIS_TestCases.M03_DCMotorSpeedControl.Controller.PID.SpeedController_continuous;
end PIDController;

I had a look in the EMPHYSIS_TestCases.M03_DCMotorSpeedControl but there are no ModelsToExport.
How is ModelsToExport defined?

Can you send me an email with the actual code so I can debug?

[Oliver Lenord]

The svn is outdated. The latest version of the test cases is on gitlab:

I cannot reproduce your bug. Running script:

loadModel(Modelica); getErrorString();
loadFile("../EMPHYSIS_TestCases/package.mo"); getErrorString();
buildModel(EMPHYSIS_TestCases.M03_DCMotorSpeedControl.ModelsToExport.PIDController); getErrorString();
buildModel(EMPHYSIS_TestCases.M03_DCMotorSpeedControl.Controller.PID.SpeedController_continuous); getErrorString();

Gets me this with the old front-end:

$ ~/dev/OpenModelica/build/bin/omc script.mos

And this with the new front-end:

Everything seems to work fine.
