  * Follow the instructions you find [http://dev.eclipse.org/newslists/news.eclipse.modeling.gmf/msg05684.html here].
  * Write a command class similar to this:
{{{
public class OpenDialogCommand extends Command {

		@Override
		public void execute() {

			TwoListsSelectionDialog dialog = new TwoListsSelectionDialog(
					PlatformUI.getWorkbench().getActiveWorkbenchWindow()
							.getShell());
			EObject exhibitionModule = ((ExhibitionModuleEditPart) getParent())
					.resolveSemanticElement();

			dialog.setList(((ExhibitionModule) exhibitionModule).getSlides());
			Object[] results = null;
			dialog.open();
			results = dialog.getResult();

			Sequence seq = (Sequence) resolveSemanticElement();
			if (results == null) {
				seq.eSet(ExhibitionPackage.eINSTANCE.getSequence_SlideOrder(),
						null);
				return;
			}

			String slideOrder = "";

			for (Object obj : results) {
				if (obj instanceof Slide) {
					slideOrder += ((Slide) obj).getSlideId() + ";";
				}
			}
			org.eclipse.emf.common.command.Command cmd = SetCommand.create(
					getEditingDomain(), seq, ExhibitionPackage.eINSTANCE
							.getSequence_SlideOrder(), slideOrder);
			getEditingDomain().getCommandStack().execute(cmd);
			System.out.println(getClass().getName() + " seq "
					+ seq.getSlideOrder());
		}

	}
