    Hello,

    with the Telerik version >= 2016.3.914.1050 we are getting following exception sporadically.

    We have no reproduction case and do not know what the reason is.

    Our code does not ouccur in the stacktrace, so we have no startingpoint we to search or look at.

    [Arg_NullReferenceException]

    Hello,

    I looked at the sourcecode an propably found the problem. there is a null check for this.Ribbon, but the null check seems to short. The check needs to include the more code which is using "this.Ribbon".

     

    private void DetachHandlers()
    {
        this.ClearSession();
        if (this.Ribbon != null)     <---here is a null check for "this.Ribbon"
        {
            this.Ribbon.SizeChanged -= new SizeChangedEventHandler(this.ClearSessionHandler);
            this.Ribbon.Loaded -= new RoutedEventHandler(this.Ribbon_Loaded);
            this.Ribbon.Unloaded -= new RoutedEventHandler(this.Ribbon_Unloaded);
        }
        if (this.openedRootVisuals != null)    <--here is a null check for "this.Ribbon" missing
        {
            RoutedEvent eventFromActivationMode = KeyTipService.GetEventFromActivationMode(KeyTipService.GetActivationMode(this.Ribbon));   <--here is the null exception
            foreach (UIElement openedRootVisual in this.openedRootVisuals)
            {
                this.DetachKeyboardEvents(openedRootVisual, eventFromActivationMode);
                openedRootVisual.RemoveHandler(UIElement.MouseLeftButtonUpEvent, new MouseButtonEventHandler(this.ClearSessionHandler));
            }
        }
        if (KeyTipService.ribbonReferences.FirstOrDefault<RadRibbonView>((RadRibbonView x) => x == this.Ribbon) != null)
        {
            KeyTipService.ribbonReferences.Remove(this.Ribbon);
        }
                                   <--the null check for "this.Ribbon" should end here
     
        this.openedRootVisuals = null;
        this.rootElement = null;
        this.tips = null;
        this.tipsStack = null;
        this.focusedElement = null;
        this.isHandlersAttached = false;
        KeyTipService.keytipServiceReference = null;
        this.UnfocusKeyboardNavigationElement();
        this.currentKeyboardNavigationElement = null;
        this.initialTips.Clear();
        this.keyboardTips.Clear();
        this.nestedPopupsStack.Clear();
        this.isKeyboardNavigationActive = false;
    }

    Hello Dominic, 

    Thank you for reporting this issue and suggesting a possible solution. We would be glad to fix this issue, but I’m afraid that we cannot do this without a project and steps to reproduce it locally. Otherwise it would be a blind fix and we cannot be sure that it solve the issue and also we cannot test it. Could you please elaborate a bit more on this scenario by sending us an isolate project with steps to reproduce. This way we can debug it locally and will be able to provide you with more information on that matter.

    As for the suggested solution - this method could be improved, however  we cannot be sure that the issue is connected only with DetachHandlers and not with more complex section of the code for KeyTips. This is why we prefer to debug it locally.

    Thank you in advance for your cooperation.

    Regards,

    Hello Milena,

    as I already wrote, we cannot reproduce it :-(

    We have the ribbon only in one screen, mostly we use the standard toolbar. So it could happen, that the ribbon is in screen and everything is ok, but sometimes later on, when the ribbon is already closed the errors occurs. But only sometimes.

    My suggestion propably fixes not the source of the probem, but as you also stated, it could and should improved, because it is obviously unsafe and produces erros.

    It crashes on DetachingHandlers(), so this would be a could place to fix, because ,it wants to Detach() itself.

    The problem is, itoccurs the with every keystoke in the application, doesn´t matter where, because the hander did not get detached and listens in the background. We have customers, they got !!several thousend exceptions!!.

    For demonstration, I attached a small logfile.

    Our only way around try to !!ignore these Telerik Exceptions!! in the global application handler, and this could not be the solution.

    Regards,

    Dominic

    Hello Dominic, 

    Thank you for the additional information and the feedback. I was able to reproduce the issue locally in scenario with TextBox and adding and removing the ribbon on keydown. I'm not sure if this is close to your scenario, but it is a start point. I logged a bug in our FeedbackPortal where you can track its progress andI have also updated your Telerik points as a small appreciation for your cooperation.

    Please excuse us for the inconvenience caused.

    Regards,

    Hello Milena,

    nice to hear, that you were able to reproduce the issue. When can we expect a fix?

    Out logfiles get pollutes with several megabytes of exceptions every day. When the errors ocurrs, it happens over and over again and produced NullException with every keystroke thousend and thousends and we don´t know if this a has other side effects.

     

    Here ist a part of out logfile....

    Hello Dominic, 

    The bug was fixed last week and it is included in our latest internal build (LIB) from 12.12.2016. You can download it from your account  and test your product with this version, so that you can verify the issue is indeed now gone. Please let us know if there is anything we have missed.

    Please note that the LIB is not an official version and use it in notion in mind. We do not recommend it for production use. This fix will be included in our upcoming release, which is scheduled for January.

    In addition I would like to add that in the future if you are using our FeedbackPortal you can take advantage of following an item there. This way you will be notified when its status is changed. 

    I'm looking forward to your reply.

    Regards,
    Milena
