Rich Search on side menu failinf randomly

Add-ons
#1

Hi

Got the following error randomly in production when using rich search. Sadly I’m unable to reproduce it in development environment, neither in a small project.

In the meantime I have extended SearchPresenterImpl.load the following way to increase robustness.

    /**
     * in case of exception, catch it, log error and return empty stream
     */
    @Override
    protected Stream<SearchEntry> load(SearchContext context, SearchStrategy searchStrategy, String query) {
        try {
            return super.load(context, searchStrategy, query);
        } catch (Exception e) {
            log.error("Error executing search strategy : " + searchStrategy.name(), e);
            return Stream.empty();
        }
    }

But I do not understand why sometimes MenuProvider.sideMenu() (below) raises a NPE.

I upgraded from 6.10.13 to 6.10.15, maybe that’s the culprit.

    @Bean("search_SideMenu")
    @Scope(value = "prototype", proxyMode = ScopedProxyMode.INTERFACES)
    public SideMenu sideMenu() {
        return ((SideMenu) AppUI.getCurrent().getTopLevelWindow().getComponentNN("sideMenu"));
    }

Hi @michael.renaud,

Sorry but we couldn’t reproduce the problem. if the problem is still relevant please provide more info about your application, what is your server environment, do you use other add-ons in your project?

Regards,
Evgeny

Hi @evgeny.zaharchenko

Jelastic / app server Tomcat 8.5.23 / PostgreSql 9.6.6

I did check production logs, it is still appearing randomly, there is an interesting burst on 4th March:

No thorough analysis of mine but I have the feeling this is a synchronisation issue, knowing that search is executed by spawning a background thread.

Following code of MenuProvider.sideMenu fails sometimes:

 @Bean("search_SideMenu")
    @Scope(value = "prototype", proxyMode = ScopedProxyMode.INTERFACES)
    public SideMenu sideMenu() {
        return ((SideMenu) AppUI.getCurrent().getTopLevelWindow().getComponentNN("sideMenu"));
    }

Knowing that getComponentNN has a distinctive error message, either AppUI.getCurrent() returns null, or AppUI.getCurrent().getTopLevelWindow() returns null.

If this is the first, maybe that’s because Vaadin does not like when UI code is accessed out of UI thread, here we are in a background thread.

Is this is the second, knowing that topLevelWindow in AppUI can change through navigating (code below) there might be some sync needed.

/**
     * Initialize new TopLevelWindow and replace current
     *
     * @param topLevelWindowId target top level window id
     */
    public void navigateTo(String topLevelWindowId) {
        WebWindowManager wm = AppBeans.getPrototype(WebWindowManager.NAME);
        wm.setUi(AppUI.getCurrent());

        wm.createTopLevelWindow(windowConfig.getWindowInfo(topLevelWindowId));
    }
