3653	Evaluation of lists (stringReal looses type?)	Henning Kiel	Martin Sjölund	"I have the following simple code:
{{{
package Main

public function main
  input list<String> args;
  output list<String> out;
protected
  list<Real> r_arr;
  list<String> s_arr;
algorithm
  r_arr := list(stringReal(s) for s in args);
  s_arr := list(String(r) for r in r_arr);
  out := listAppend(args,s_arr);
end main;

end Main;
}}}

I run it with omc +g=MetaModelica and the following script:
{{{
loadFile(""Main.mo"");
getErrorString();
Main.main({""1"",""2"",""3"",""4"",""5"",""6"",""7"",""8""});
getErrorString();
}}}
and get the following error:
{{{

So, list(stringReal(...)...) seems to loose information of element type (should be modelica_real, but is modelica_metatype)."	defect	closed	critical	1.9.4	Code Generation		fixed		Martin Sjölund
