Navigating to new fragment, then back to BottomNavigationBar fragment

[c-lamont]

I have three tabs in my BottomNavigationBar.

Clicking on a tab replaces a FrameLayout with a Fragment.

If I navigate from the Fragment holding the BottomNavigationBar, to a new fragment, then back to the BottomNavigationBar Fragment, the BottomNavigationBar is gone and the Fragment loaded into its Framelayout is also gone.

I have tried attaching the BottomNavigationBar to the Activity and to a view inside the Fragment Layout. In the Fragment, all views disappear and in the Activity, the Bottom Bar remains but the loaded fragment is gone.

Is this a bug/not possible?

Thanks Chris

This is a problem with fragments and not related to the navigation bar.
