Description Sanjeev Rao Lade 2017-05-12 10:31:46 UTC
I am developing an application that uses the XFNavigation.
I have multiple pages, where some pages has to validate for data on back button pressed.
If I tap/click back button at normal speed, OnBackButtonPressed is getting triggered properly.However If I tap/click back button at faster rate (Click back continuously), OnBackButtonPressed is not is triggering on parent Pages.

Let say I have Pages of  P1 -> P2 -> P3 -> p4 and have to validate data on P2 every time.
Normal click - From : P4 -> P3 -> P2: Triggering OnBackButtonPressed.

Continuous Click: From P4 -> P3 -> P2 -> P1 OnBackButtonPressed is not triggered
