4245	Problems with inheritance of the MultiBody.World model	Francesco Casella	Per Östlund	"Consider this simple test case
{{{
package TestWorldExtends
  model World
    extends Modelica.Mechanics.MultiBody.World(n = {0, 0, -1});
  end World;

  model Example
    inner World world;
  end Example;
end TestWorldExtends;
}}}
If I compile the {{{Example}}} model in OMC I get
{{{
Translation Error
[Modelica.Mechanics.MultiBody: 1431:3-1439:110]:
Variable Types.GravityTypes.PointGravity not found in scope TestWorldExtends.World
}}}
The model works in Dymola. I'm not sure if this is an OMC problem or a Modelica 3.3r1 specification problem, that actually does not allow this, while Dymola supports it anyway. Can you please have a look?"	defect	closed	critical	2.0.0	New Instantiation		fixed		Andrea Bartolini
