[Etienne13]

Summary

If a BA subclause contains a subprogram call action that refers to something else than a subprogram classifier (e.g. subprogram access or subprogram subcomponent) the plugin throws an error.

Steps to Reproduce

1. create a package with the following example
2. the BA plugin throws an error on subrogram access call

package BA_example1
public

data number
end number;

subprogram mul
features
  x : in parameter number;
  y : in parameter number;
  z : out parameter number;
end mul;

subprogram cube
features
  x : in parameter number;
  y : out parameter number;
  mul : requires subprogram access mul;
end cube;
subprogram implementation cube.ba
annex behavior_specification {**
  variables tmp : number;
  states s : initial final state;
  transitions t : s -[]-> s { mul!(x,x,tmp); mul!(tmp,x,y) };
**};
end cube.ba;

end BA_example1;
