I noticed a quirk when testing some code that prevents navigation in before show, as indicated here ... http://docs.kendoui.com/api/mobile/view#events-beforeShow
If I use this technique the tabstrip changes the active tab to the view that was prevented from being displayed, I have a jsfiddle here
that demonstrates the issue. Notice that if you are on view 1, or the view 1 child and you select view 2 (the one that is supposed to be prevented), the navigation is prevented but the tab strip is active on view 2. I would expect the tabstrip to keep the same tab active as a result of the e.preventDefault call, but perhaps this is deliberate behavior.
I have a work around for the issue (I just alter the content on view 2 instead of stopping them from navigating to it which is fine for my purposes), so I don't need a fix in a rush I just thought I would bring it to your attention in case you weren't aware.
