Imagine that we want, in OMEdit, create a new model, named MyModel, coat consistes on a sine and an integrator integrating the sine output.

Do the following:
1) drag sine in MyModel
2) drag Integrator into the model
3) connect the sine output with the Integrator input.

The following code is produced:

model MyModel
  BugDrag.sine sine1 annotation(Placement(visible = true, transformation(origin = {-54, 0}, extent = {{-10, -10}, {10, 10}}, rotation = 0)));
  BugDrag.Integrator integrator1 annotation(Placement(visible = true, transformation(origin = {-6, 0}, extent = {{-10, -10}, {10, 10}}, rotation = 0)));
equation
  connect(integrator1.u, sine1.y) annotation(Line(points = {{-18, 0}, {-44, 0}, {-44, 0}, {-44, 0}, {-44, 0}}, color = {0, 0, 127}));
  annotation(Icon(coordinateSystem(extent = {{-100, -80}, {100, 80}}, preserveAspectRatio = true, initialScale = 0.1, grid = {2, 2})), Diagram(coordinateSystem(extent = {{-100, -100}, {100, 100}}, preserveAspectRatio = true, initialScale = 0.1, grid = {2, 2})));
end MyModel;

that does not check, because the substring "BugDrag."
If the package is not encapsulated the issue is not there.

I think we have here two issues:
1) the prefix containing the package name (here "BugDrag") should not be automatically added, at least for encapsulated packages
2) OMEdit shows these dragged models as being correct, even though they are not accessible. SInche their pathnames make them non-accessible, they should be displayed as red boxes.
