Tab issue on public show business fragment.

When the screen orientation changes, or the activity is torn down and rebuilt, the tab reverts to its original state.

It is not possible even to force the tab to switch back after the view is created.

Most likely this will involve trial and error experimentation by overriding different handlers on the fragment, or possibly the containing activity (although I want to avoid that at all costs, since it violates good OOP design principles).
