public void doAfterCompose(@ContextParam(ContextType.VIEW) Component view,@ContextParam(ContextType.BINDER) Binder binder) {

    Object object = SelectorsExt.subscribeEventQueues(this);

    //SelectorsExt.ExtendedUtilityHandlerImpl extendedUtilityHandler = new SelectorsExt.ExtendedUtilityHandlerImpl();
    //extendedUtilityHandler.postSubscriptionHandling(object, view);

@Subscribe(value = "on.update", scope = "application", eventName = "on.update")
public void test(String value){


Above code is not autounSubscribing, if enabled commented lines only autoUnsubscribing is working.

Auto-Unsubscribed only works when using SelectoComposer by default instead of a ViewModel. Please see Auto-Unsubscribed.

Since you call SelectorsExt.subscribeEventQueues(this); in a ViewModel, your @Subscribe still works and can receive events from an event queue.

If you check ServerPushEventQueue.subscribe(), it add a listener EQCleanup that will remove the subscriber's listener when a desktop is destroyed:

_dtInfos.put(desktop, di = new DesktopInfo(desktop, new EQService(), new EQCleanup()));

So, you don't need to call postSubscriptionHandling().

Thankyou, do you mean "SelectorsExt.subscribeEventQueues(this);" is enough to take care auto Unsubscription when exited from respective viewModel?

yes, it adds a listener EQCleanup that will remove the subscriber's listener when a desktop is destroyed. just like unsubscribe.
