Resimulate doesn't read the updated value from resource file

[Adeel Asghar]

• Load the attached package in OMEdit
• Simulate model ParametersTest.M
• Update the value of parameter a from 5 to 3 in the Resources/parameters.txt file.
• Resimulate the model.

This is working fine in 1.14 so its a regression.

test with two different parameter values

Works perfectly fine for me (see attached file test.mos to reproduce). It gives me follwing output:

Is this not what you would expect?

Tested on Ubuntu 18.04 with latest omc OMCompiler v1.16.0-dev.438+g65a42873ff.

Ah i see now. You resimulate from the variable Browser in OMEdit right?

[Adeel Asghar]

Your script calls simulate which is not really a resimulate as it calls the translation of model again.

actual failing mos

[Karim Adbdelhak]

I added test_2.mos script which showcases the problem. This is due to NF evaluating the function which reads the file.

Model after new Frontend:

class ParametersTest.M
  constant String config.paramFile = "/home/kab/Repo/FH/promotion/modelicaLibs/ticketTests/6030_resimulate/ParametersTest/Resources/Parameters.txt";
  parameter Real config.a = 3.0;
end ParametersTest.M;

Fixed in 0c5b95d.

Thanks @Per!

Thank you folks! If we keep on fixing tickets at this pace, in a couple years the backlog will be gone :)

Nah don't be scared, i am already brewing up the next bugs. ;)
