Fragment Feature not function in tabbed application #40

Closed powellbird closed 7 years ago

powellbird commented 8 years ago

The feature FormFragment only works if you set it on the same page of the activity, when I use tabLayout and FragmentPagerAdapter tabbed this does not work because when changing TAB, and want to use the controls, causes a null value and the application stops function.

Example I have three fragments with different controls when changing tab and want to capture information in a text or change value in a picker marks the next error.
