Placing bordered nodes at the same location when copying a model element [message #1842739]

I am implementing some Java services for allowing changing the type of certain elements:
index.php/fa/40710/0/

In the java service, I create a new model element, copy the old attributes and delete the original model element.

I finally managed to make Sirius place it in the same location and with the same size as the previous element, but I can't place the pins on the Container edge at the same position on the new container.
index.php/fa/40712/0/

How should I do it?

Calling the service in an Operation "changeContext" like:

aql:self.oclAsType(myPackage::Component).transformToComponent(views)

And here is the Service code so far:

public void transformToComponent(Component c, ArrayList<EObject> containingViews) {
		final Component newComponent = myFactory.eINSTANCE.createComponent();
                // ... copy attributes ...

		// Give to the new component the same size/position as the old one.
		if (containingViews != null && containingViews.size() > 0) {
			DNodeContainer existingNode = (DNodeContainer) containingViews.get(0);
			IGraphicalEditPart editPart = getEditPart(existingNode);
			if (editPart instanceof ShapeEditPart) {
				ShapeEditPart part = (ShapeEditPart) editPart;
				SiriusLayoutDataManager.INSTANCE
						.addData(new RootLayoutData(existingNode.eContainer(), part.getLocation(), part.getSize()));
			}
			
			//TODO: Place bordered nodes at the same position:
			existingNode.getOwnedBorderedNodes().stream().forEach(bn -> {
				IGraphicalEditPart editPart2 = getEditPart(bn);
				System.out.println(editPart2.toString());
				if (editPart2 instanceof ShapeEditPart) {
					ShapeEditPart part = (ShapeEditPart) editPart2;
					SiriusLayoutDataManager.INSTANCE
							.addData(new RootLayoutData(bn.eContainer(), part.getLocation(), part.getSize()));
				}
			});
		}

		// Delete the old component
		EcoreUtil.remove(c);
	}

Thanks in advance for any hint :)
