InjectionException when creating new window [message #1727633] Thu, 24 March 2016 14:54 Go to next message

I am trying to launch a perspective in a new window. The main window is an MTrimmedWindow and the new window that will open is an MWindow. Whenever the new window opens, however, I get an InjectionException. I am trying to open the new window like this:

        final IEclipseContext context = originalWindow.getContext();
        final MApplication application = context.get(MApplication.class);
        final MWindow newWindow = MBasicFactory.INSTANCE.createWindow();
        application.getChildren().add(newWindow);
        final EPartService partService = application.getContext().get(EPartService.class);
        final MPlaceholder placeholderPart = partService.createSharedPart(gadgetId);
        final MPerspective perspective = createPerspectiveWithPlaceHolder(PERSPECTIVE_ID, placeholderPart);
        final MPerspectiveStack perspectiveStack = AdvancedFactoryImpl.eINSTANCE.createPerspectiveStack();
        perspectiveStack.getChildren().add(perspective);
        newWindow.getChildren().add(perspectiveStack);


Here is the stack trace I'm seeing:
!MESSAGE Exception while dispatching event org.osgi.service.event.Event [topic=org/eclipse/e4/ui/model/ui/ElementContainer/selectedElement/SET] to handler org.eclipse.e4.ui.services.internal.events.UIEventHandler

Can I not have an MTrimmedWindow and an MWindow? If I change the new window to be an MTrimmedWindow as well, the exception goes away, but it breaks the rest of the application and I don't want the new window to be full screen. Any help with this issue would be greatly appreciated.

Adding the new window as a child of the original window like
originalWindow.getWindows().add(newWindow);

gets rid of the exceptions. Unfortunately this also removes the close button from the window, so I am working on figuring out how to add the close button back now.
