How to close a part when error occurs during initialization in eclipse e4 rcp?
Closing the part in the @PostConstruct method is probably confusing Eclipse. Try using UISynchronize.asyncExec to run the code after the @PostConstruct has finished running. Something like: @Inject private UISynchronize uiSynch; ... @PostConstruct public void postConstruct() { .... other code uiSynch.asyncExec(() -> { ... hide the part }); } ...
How to get the view by viewId in RCP?
The IWorkbenchPage has the methods to control views: IWorkbenchPage page = PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActivePage(); IViewPart viewPart = page.showView("view id"); The part createPartControl will be called when the view is created, on subsequent calls to showView it is not called. The viewPart will be an instance of your view class so you can...
RCP: How to sync state of MMenuItem and MToolItem

When you add the 'Handler Tool Item' to the Toolbar in the Application.e4xmi you can specify the 'Type' as 'Check' to get the pressed / not pressed behavior. In your Handler for the item you can inject the 'MToolItem' so that you can test the checked state: @Execute public void...
RCP - Application does not have an active window
Use the active leaf context: IEclipseContext activeContext = application.getContext().getActiveLeaf(); EPartService partService = activeContext.get(EPartService.class); I don't think the model and part service actually change so just using application.getContext() should also be OK. The application object does not change....
Restart Eclipse 4 RCP application before it gets visible
Probably the earliest you can get the workbench is by subscribing to the application startup complete event UIEvents.UILifeCycle.APP_STARTUP_COMPLETE with the event broker. However this does not fire until just after the UI is displayed. Update: The event handler would be something like: private static final class AppStartupCompleteEventHandler implements EventHandler {...
Eclipse RCP: NullPointer on getSite().setSelectionProvider(…)
Eclipse 4 (e4) applications are completely different from traditional Eclipse 3.x style applications. In an e4 application you cannot use a lot of things that are used in a Eclipse 3.x application - so you need to check which style the example you are using is based on. The e4...

installing swtChart RCP/SWT- java.lang.ClassNotFoundException: org.swtchart.Chart

Eclipse RCP - Perspective Layout
The order in which you declare the views is important in getting the view to stretch across the whole window.

How to build two different versions of an e4 RCP application with Maven/Tycho?
