4448	ExternData library is not working in OpenModelica	musa_me4@…	Adrian Pop	"The ExternData library works in Dymola and SimulationX, unfortunately, it is currently not working in OpenModelica. The library developed mentioned this in the documentation and suggest a quick fix (https://github.com/tbeu/ExternData). However, the fix does not work in OpenModelica. (please check this discussion board https://github.com/tbeu/ExternData/issues/9#issuecomment-308656184). By using a stand-alone function as suggested by the library developer-

package Test
  extends Modelica.Icons.Package;
  function __OpenModelica_getReal ""Get scalar Real value from XML file""
    extends Modelica.Icons.Function;
    input String fileName="""" ""File where external data is stored"";
    input String varName ""Key"";
    output Real y ""Real value"";
    protected
      ExternData.Types.ExternXMLFile xml = ExternData.Types.ExternXMLFile(fileName) ""External XML file object"";
    algorithm
      y := ExternData.Functions.XML.getReal(xml=xml, varName=varName);
    annotation(Inline=false);
  end __OpenModelica_getReal;
  
  model XMLTest ""XML file read test""
    extends Modelica.Icons.Example;
    parameter String fileName = Modelica.Utilities.Files.loadResource(""modelica://ExternData/Resources/Examples/test.xml"");
    Real test = __OpenModelica_getReal(fileName, ""set1.gain.k"");
    annotation(experiment(StopTime=1));
  end XMLTest;
  annotation(uses(ExternData(version=""2.2.0""), Modelica(version=""3.2.2"")));
end Test;

XML test compiles without any error but when I try to run it gives following errors.

Any kind of help on this issue will be very helpful. Thanks."	defect	accepted	high	Future	Code Generation	v1.12.0		ExternData	Adam Dershowitz
