I would need to see a full exampl, but this will give a parser error as record extends needs a definition (i.e. ConstantRecord /* defs */ end ConstantRecord).

Using Dymola with this code i don't receive any error or warning. When I try to use it with OM, loading it in the editor it crashes. Trying that in the shell i don't receive any error or warning as well.

In the previous post, i don't know why but the the entire code wasn't posted. As you can see in this code here, the code is a part of the Modelica.Media.Interface.PartialMedium and Modelica.Media.Interface.PartialSimpleMedium

-------
package test

     import SI = Modelica.SIunits;
     extends Modelica.Icons.Library;

partial package test2
  constant Modelica.SIunits.HeatCapacity cp;

     replaceable record aaa
      "Minimal variable set that is available as input argument to every medium function"
      extends Modelica.Icons.Record;
      SI.Density rho "Density";
     end aaa;

end test2;

partial package test3
extends test2;
redeclare record extends aaa "Thermodynamic state of ideal gas"
      SI.Pressure p "Absolute pressure of medium";
      SI.Temperature T "Temperature of medium";
end aaa;

end test3;

end test;

Still I can't see the full code, but if your OMEdit crashes on the Media models, you just need a newer version as I think it fixed some of these issues.

i don't know the company pushes us to use f.... IE and i don't know why but it has some problems with the posting. Now is the entire code.

you can see now the simple code.

Thank you

And I'm using as i mentioned before the latest OM version 1.8 BETA2

Ok, the latest version of OMEdit doesn't crash. It can load the file correctly, but not edit it (it will randomly move classes around or crash when modifying the class). I will forward this to Adeel

Thank you. I thought it's up to me and my "modeling"

Cheers,

Is this with the new nightly build solved or is it a bigger issue?

cheers,
