How is it possible to clone the first window of a pure e4 rcp application?

it is possible to open a new Window easily and define it in the model. But we would like to have a similar action like in Eclipse IDE open new Window. Where you have again all perspectives and Menues available.

MWindow newwindow = (MWindow) modelService.find(ContextConstants.NEW_WINDOW_ID, application);
        newwindow.setVisible(true);       
        newwindow.setOnTop(true);
        newwindow.setToBeRendered(true);
        modelService.bringToTop(newwindow);

We tried as well with the clone method but we get a NPE there.

 MWindow cloneswindow = (MWindow) modelService.cloneElement(window, application);
        modelService.bringToTop(cloneswindow);

Caused by: java.lang.NullPointerException
	at org.eclipse.e4.ui.internal.workbench.ModelServiceImpl.bringToTop(ModelServiceImpl.java:383)

Try putting

application.getChildren().add(cloneswindow);

before

modelService.bringToTop(cloneswindow);
