It looks like you are using the Application EPartService to try and close a part. This will not work when a dialog is open as there is no active window which the application part service needs.

Instead you need to use the part service for the top level window. Get this using something like:

@Inject
EModelService modelService;
@Inject
MApplication application;

MWindow window = (MWindow)modelService.find("id of your top level window", application);

EPartService partService = window.getContext().get(EPartService.class);
