    Seems there is a problem with tap not working on first try after you scroll the list up and down. It is happening on http://demos.kendoui.com/ Mobile demos, as well as in my test app. Tested on iPhone 4s and Samsung Galaxy S3 devices. The behavior is the same.

    I apologize if this was already asked or in the queue for fixing.

    Thank you.

    Hi Miljan,

    Can you reproduce this using our online demos as well? I have tried it bit it seems to be working correctly. Please make sure that the animation is finished when you click the ListView item, as the behavior that you describing might be because the animation is not done, when you click the ListView.

    Yes. It does happen in online demos and I can recreate 100% of times.
    It seems that there is animation problem indeed. It doesn't ever complete if list stops scrolling, you still have your finger on, and you remove the finger from screen straight up. In that case scroll bar remains visible and first tap doesn't work, but just hides the scroll bar (I guess on first tap animation completion is triggered).

    I recorded the video using iPhone emulator. As I noted in first post, it happens on iOS and Android actual devices  as well.

    Thank you.

    Hi Miljan,

    Thank you very much for the video.

    I have managed to reproduce the problem and on first look it seems that when you scroll with your finger and leave the application (go to the address bar) the touchend event of the scroller is not fired, which causes the persistent scroller. When you tap again the touchend event is fired correctly. 

    I will forward this to our development team for further investigation, and I will send you an email as soon as I have more information about it.

    Thank you very much for your patience.
